10 Fun Facts About Industrial Cranes

10 Fun Facts About Industrial Cranes

Whether you’re working within the rigging industry or not, cranes have become a very large part of people’s lives. Cranes have become a part of our cities skylines, even if you haven’t noticed it! They are such an integral part of construction and development that they can sometimes blend right into the background. They are massive tools that make the existence of much of our infrastructure possible.

A crane bird

Since cranes are such a large but underappreciated part of not only our industry but community, we thought it would be fun to share 10 fun facts you may not have known about cranes. Read on to learn more!

1. Cranes are Named After the Bird

If you google the word crane, you’ll get a mixture of lifting cranes and this fun looking bird, also called a crane! Have you ever wondered why these two share a name? It’s because lifting cranes were actually named after the bird. Crane birds are tall and slender, bendy, and quick with their beaks, so lifting cranes got their name because early crane manufacturers thought they looked like these birds – do you agree?

2. Cranes were Invented in Ancient Greece

The first crane was built by the Ancient Greeks in 500 BC. The first crane was a primitive, wooden form powered by humans and animals, used to pull heavy objects and construct many of the beautiful structures that existed in Ancient Greece. One of the Greek’s most famous buildings, the Parthenon, shows evidence of cranes used in its construction.

3. Jibs Changed the Game

In the Middle Ages, what we know now as a Jib was added to the Greek crane which allowed the crane’s arm to move horizontally and not just vertically! Following this advancement, cranes began to first be used in harbors to unload cargo from ships – something that modern cranes are still doing now. By the sixteenth century, cranes were built with two treadmills, one on each side of a rotating housing containing the boom.

4. From Wood to Steel

As mentioned above, the earliest cranes in ancient Greece were made of wood which did the trick back in the day but wouldn’t have the strength to stand up against some of the jobs modern cranes take on today. Now, cranes are usually manufactured using steel.

5. The First Powered Cranes Were Powered by Steam

Until the middle of the nineteenth century, cranes still relied on human or animal power. What changed that? The invention of the steam engine! This technology was introduced to cranes and allowed them to be powered by a motor. By the end of the nineteenth century, internal combustion engines and electric motors were used to power cranes.

6. Cranes Build Themselves!

That’s right, cranes oftentimes build themselves. The only thing large enough and strong enough to build cranes, is other cranes. With the help of workers, operators use the crane to attach vital pieces of equipment. Sometimes cranes will literally build themselves placing pieces onto itself once the control panel is up and running – how cool is that!

7. There are Many Different Types of Cranes

Different types of cranes can be found on almost any construction project, each one specializing in its own specific task. Here are just a few of the most popular ones:

  • Mobile Cranes – A mobile crane is a cable-controlled crane mounted on crawlers or rubber-tired carriers or a hydraulic-powered crane with a telescoping boom mounted on truck-type carriers or as self-propelled models.
  • Carry Deck Crane – A carry deck crane is a small 4 wheel crane with a 360 degree rotating boom housed in the center of the machine.
  • Crane Vessel – A crane vessel, crane ship or floating crane is a ship with a crane specialized in lifting heavy loads. The largest crane vessels are used for offshore construction.
  • Rough Terrain Crane – As the name implies, these cranes are used for pick and carry operations off-road and on rough terrains.

8. The Current Largest Crane in the World

The SGC – 250, the Sarens Giant Crane also known as ‘Big Carl’, is a 250,000t/m heavy crane designed to sgc-250 craneaccommodate the heavy lifting requirements for refinery, oil and gas, mining, offshore platform, and third-generation components for nuclear power plants.

Built in 2015, this crane has a maximum lift capacity of 5,000-tons and features a 118m – 160.5m main boom configuration with a 40.5m – 99.5 m heavy-duty jib configuration. It operates on a 48.5m outer ring and requires a 5,200-ton counterweight. The jib can be extended up to 100 meters, giving it a maximum height of 250 meters (820 feet) and radius 275 meters (902 feet).

The SGC – 250 can operate on two different blocks at the same time—One on the main boom and one on the jib. The crane’s main hook block weighs 105 tonnes and has a safe working load (SWL) of 3,200 tonnes while the jib hook weighs 58 tonnes and has an SWL of 1,600 tonnes.

9. The Strongest Mobile Crane

Designed by Liebherr, located in Switzerland, the mobile crane, LTM 11200-9.1, is the strongest telescopic LTM 11200-9.1 cranemobile crane in the market and offers the world’s longest telescopic boom. It has a maximum lift capacity of 1,200-tons, a maximum hoisting height of 188 meters (616 feet) and a maximum radius of 136 meters (446 feet) – This is over the length of a football field! 

Some of the features found on the LTM 11200-9.1 are:

  • 100m long telescopic boom and 22m telescopic boom extension.
  • Lifting capacity of 65-tons at the 100m long, suspended telescopic boom.
  • 126m long luffing fly jib.
  • 60.5m long fixed jib, optionally hydraulically adjustable.
  • Fast and easy crane assembly with little required space.
  • Active, speed dependent rear-axle steering (all axles can be steered).
  • Economical transportation.

The LTM 11200-9.1 has been used to assemble larger portal cranes, radio towers, absorber columns, and wind power generators. When fully-loaded the base of the vehicle drives with slewing platforms, luffing cylinder and all four folding beams—With all of these elements, it will weigh in at over 100-tons. However, dismantling these elements is easy to do, making it so you only have to travel with what will be used on the job. Doing this can lessen the total weight to 34-tons, making it much more economical to transport.

10. Cranes can be Dangerous

As much as we admire the beauty and versatility of cranes – At the end of the day, they are a very large and potentially dangerous piece of machinery. Failure to follow safe lifting practices can lead to serious personal injury and cause damage to equipment and facilities. However, with proper training, inspections & maintenance, and workplace protocol you can greatly reduce the likelihood of many safety hazards. Hercules SLR can help with that!

We’re your one-stop-shop. Would you make three different stops in the morning to get your sugar, milk, and grounds for your morning coffee? Of course not—Why should your crane service be any different?

What’s a Banksman? An Important Rigging Role

What’s a Banksman? An Important Rigging Role

Have you ever needed to back your vehicle out of a difficult position and had a friend grab a better vantage point to guide you? In these situations, you may be able to hear your guide – but oftentimes rely on them signaling you to move, turn, or stop using hand signals.

Now, imagine that on the scale of operating a crane! A crane operator can’t hear you. So when your team removes an old rooftop unit and positions a new one, the people on the ground and on the rooftop must use established hand signals to communicate safely with the crane operator – that’s the role of the banksman! Of course, that’s boiling it down a bit, but largely the banksman is in charge of crane movements from the point of loading to unloading. A banksman may also control the movements of other equipment such as an excavator, by carefully monitoring the bucket for any obstructions or underground services. They often do this using a system of hand signals along with possibly a radio system.

Why the Worksite Needs a Banksman 

The role of the banksman is one of the most important roles on the worksite. Ask any crane operator and they will tell you that one of the main factors for a successful project is coordination. Working in-sync with your team on the ground is not only crucial for safety but can help your project run smoothly, on schedule and keep the boss happy. With absolute precision and accuracy needed for a job, being able to clearly communicate direction is critical – but this is not always an easy task.

It’s easy to imagine needing to use hand signals when communicating to the crane operator, but they are also needed on the ground. Construction sites can be exceptionally loud and busy, meaning verbal communication is at risk of being drowned out by roaring machinery.

As the eyes and the ears of a dedicated area or crane, a banksman carries many responsibilities.  Before a person can direct the operation of a crane they must first undergo formal training and complete a qualification in crane signaling. In training, a person will not only develop an understanding of standard hand signals, but they will also be required to become familiar with many different types of cranes, how each crane functions and any hand signals specific to particular equipment. The trainee banksman is required to grasp an understanding of the large library of signals without any memory prompts and show competence in recalling these during an examination by a third-party provider.

The Occupational Safety and Health Administration (OSHA) standard method of signaling must be used when operating a crane unless non-standard hand signals are discussed during the pre-job meeting. OSHA enforces standards and training requirements for safe working environments across multiple industries, including construction in the United States.

Keeping the Worksite Safe

The banksman is also responsible for preventing injury and accidents to the best of their ability, this is done by following strict procedure during crane operation, for instance standing in clear view of the crane operator, ensuring the operating area is clear of people or hazardous objects and performing one signal at a time to avoid confusion.

Safety is the number one concern for crane operators, a person performing the hand signals stand at a vantage point which allows them to view the load area from a perspective that is not visible to the crane operator. From this point, the signal person is able to confirm whether a maneuver is safe to perform and halt all activity if they observe a potential risk.

Cranes have incredible capabilities however if operated incorrectly, they can pose a significant danger to construction workers on the site and in some cases the public.  Hand signals have been established as a reliable, low tech and universal way to improve safety during operation and avoid accidents.

The Hand Signals

This age-old technique is used by crane operators across the world, aiding them to accurately receive unmistakable directions without the need for fancy equipment or even words!

Industry Highlight | Film and Television Rigging

film and tv entertainment rigging

Industry Highlight: Film & Television 

Lights, Camera—Rig?!

It’s easy to think of only industrial applications when we talk rigging, but rigging’s found everywhere—Especially behind the TV screen in the entertainment industry.

When making a feature film or TV show, it takes many people behind the scenes running the lights, camera, sets, costumes, makeup…and the rigging! In the film industry, rigging technicians are referred to as grips. Although it’s one of the lesser-known film-industry teams, they are an integral part of many different aspects within film-making.

Next time you’re enjoying a movie full of fun camera angles or high-speed Hollywood chase scenes—Know that a grip made that possible!

What Does the Grip Department Do?

The grip department is in charge of all rigging needs behind the scenes—Lifting, carrying, transporting, rigging, operating, building, and placing production equipment where it needs to be. This means they’re in charge of all equipment that helps to lift or hoist other equipment, often with a main focus on:

  • Camera rigs – Used to stabilize camera movements or to achieve difficult angles
  • Lighting rigs – Used to achieve specific lighting techniques or effects.

But it doesn’t stop there. Grips often play more roles then the actors on set, including the role of carpenter, electrician, mechanic, and of course, rigger. They’re the people who make showbiz function.

The grip team is often led by what is referred to as the “Key Grip”, the team lead, and the “Best Boy”, the second-in-command.

Rigging Equipment Used in Film

Grips have to be ready to be thrown into many different types of rigging jobs on set working with equipment like:

  • Tripods
  • Dollies
  • Tracks
  • Jibs
  • Cranes – Want to see a camera crane in action? Check out this video.
  • Static Rigs
  • Camera Mounts
  • Light Mounts

Rigging Grips often work with specialized companies to tailor-make pieces of equipment to facilitate what’s needed for the specific production. Things like difficult camera maneuvers sometimes require specialized equipment, especially if the filming is taking place in a location with extreme terrain and/or severe weather conditions.

Check out this video by the RocketJump Film School that goes through some of the equipment used by Rigging Grips and how to use it!  Pigeon plate? Gobo head? Quarter apple? Yes, these are real terms and not random gibberish! Of course, it makes sense a fun job like this would mean lots of fun nicknames for the rigging equipment used.

One of the key types of equipment you’ll see featured in this video are different types of lifting clamps. Lifting clamps are used to latch onto plates, sheets, grinders, pipes and other materials for positioning, hoisting and transferring. This eliminates the need for creating a hitch or drilling into the material—A key element when working on sets that can’t be modified for rigging purposes.

Hercules SLR sells Crosby lifting clamps with a variety of working load capacities and jaw opening sizes. Crosby lifting clamps are produced using advanced manufacturing techniques and are able to withstand abusive field conditions. Each clamp is individually proof tested to two times the working load limit and you’ll always find the Crosby logo, working load limit (WLL), jaw opening, unique serial number, and proof load test date permanently stamped on the clamp bodies.

How Grips Facilitate Safety on Set

Like we always say here at Hercules SLR, rigging is all about safety. The end goal of any rigging task should always boil down to getting the job done while keeping the people, product, and environment unharmed. Since Grips are responsible for all of the rigging on set, they also become responsible for some of the most important safety precautions.

As the video above goes through each of the pieces of hardware and how to use them – They are sure to mention what measures are necessary to keep the equipment safe and secure. Nobody wants expensive lights or other film equipment falling mid-shoot and smashing into a million pieces, and more importantly, nobody wants that to happen over an actor or crew member’s head!

Some of the mentioned safety measures include:

Cotter Pins: Cotter pins act as a locking mechanism and prevents parts from slipping off other parts.

Safety Cables: Safety Chains are an important part of many different applications of rigging and simply stops the fixture from falling if the hardware fails. The safety is attached to the hardware and looped around the beam or bar it is attached to. This way if the clamp fails, the fixture will only drop a short distance and be caught by the chain.

Safety Tip – Always check the weight rating set on safety chains to ensure it can take the weight of the clamp and anything it’s holding – Otherwise, it too will break in case of the hardware failing! 

Sandbags: Sandbags are a popular choice for counterweights in the film and theatre industry. In the video, you see them used to weight down a floor plate, but they are also used to secure scenery and props, balance hemp rigging, and a variety of other purposes. They come in a variety of sizes and weights!

Cribbing: Cribbing is used only when clamping on a wooden surface as there is little way to tighten a clamp onto a wooden surface enough for it to be secure, without damaging the wood. Cribbing refers to two pieces of wood that you place on either side of the wooden surface so you may tighten the clamp as much as needed without worrying about damaging the structure itself. This may be seen as more of a cosmetic precaution in other industries, but within the film industry, it’s the only way they can tighten their clamps to a safe point while on the set of a historical home, school or hospital.

Rope Access

As you would imagine, filming doesn’t always take place in locations that are set up for rigging. Often times Grips are faced with figuring out how to rig in tricky locations that may seem impossible to reach. So how do they do it? Rope access!

Rope Access is an innovative access solution that enables a technician to use two ropes and a harness system to position themselves in nearly any work environment. This eliminates the need for scaffolding or other heavy access equipment in locations that simply can’t support it. Using the unique gear system, the grip can maneuver themselves with complete 360-degree mobility in difficult locations while completing the task at hand.

Confined space training may be necessary based on the environment they are working in, and is a great way to ensure the safety of your team while rigging in tight locations. Confined Space Entrant/Attendant
Training (CSEA) is just one of the many courses available at the Hercules Training Academy

Revolutionary Rigging | The Spydercrane

Revolutionary Rigging | The Spydercrane

What’s a spydercrane? Although this spyder is a little bit too big to squish with your shoe… No need to worry arachnophobes, the only thing the Spydercrane and the actual creepy-crawly have in common are it’s 4 long legs which give it a spider-like appearance.

This new crane is much like a boom lift, but its small base and spyder legs or ‘outriggers’ makes it much more versatile than the typical boom lift.

The spydercrane was originally manufactured by Furukawa UNIC Corporation in Japan, and is called the Mini Crawler Crane. Roger Bassetti and Warren Wagoner from Phoenix-based Smiley Lift Solutions saw the crane while on a business trip to Japan and immediately knew that they needed to bring the mini crane technology to the North American Market. So, the Spydercranes we see around the US and Canada come from Smiley Lift Solutions!

What Makes the Sydercrane Special?

Here you see the Sypercrane easily wheeling through a doorway in travel mode

The key feature of the Spydercrane is that they offer a compact design that allows for operation in confined areas. The smaller models are able to travel through a standard width door frame when compact into their ‘travel position’ and the largest of the models are able to travel through a standard double-door.

Travel-mode in the larger Spydercrane models also includes a quick disassemble system that allows the outriggers, boom, and frame to be removed reducing the overall weight of the crane for transporting or hoisting.

You may be starting to get that “it’s too good to be true” ring in the back of your mind thinking it must be an absolute pain to get a crane from all tucked up in travel mode to a useable piece of equipment. However, you can easily set up a typical Spydercrane from travel mode to fully deployed and ready for action in less than 5 minutes! Don’t believe it? Check out this video from GLG Canada showing in real-time just how easy the Sydercrane set-up is!

Many of the models of Sypdercrane come with some other cutting-edge features that make the Sydercrane even more unique. Some of these include:

It’s patented Overturn Protection System: This is comprised of an on-board computer system that continually measures the ground pressure of each of the outriggers through an incorporated “load cell”. During a lift, if the system detects an outrigger is losing ground pressure, an alarm will sound and the crane will start to slow done all functions. If two outriggers start to lose ground pressure, the crane will automatically stop all functions that would put the crane closer to an unsafe position. With the alarm sounding and the crane at a safe stopped position, the operator is able to maneuver the crane back into a safe lifting position.

Variable Geometry Outriggers: The outriggers are designed to allow for lifts in tight spaces. It allows for the outriggers to be locked in numerous positions on the swing, knee, and inner box joints. This means the mini crane can be set up around obstacles, on a catwalk, or in a machinery room with very limited space.

Remote Control and Pressure Sensitive Controls: Unlike most cranes, the Spydercrane offers pressure-sensitive controls that will speed or slow the crane’s functions based on the amount of pressure input by the operator. Most models of the Spydercrane are also equipped with a wireless remote control so the operator themselves can be in the best vantage point for the lift, rather than needing to be on board running controls.

Superior Materials and Construction: The Spydercrane is designed with a hexagonal keeled boom instead of the standard square boom, which adds strength and reduces sway. This is made up of steel that is rated at 140,000 – 160,000 yield (psi), which is the highest tinsel-yield steel making it thinner and lighter but still stronger than most conventional crane materials.

Spydercrane Models

090 Series

This series is made for job sites requiring a small crane with a boom length of 18 – 28.4 ft and a maximum lifting capacity of 1,990 lbs. There are three models in this series, the URW094, URW095, and URW095S, which are all generally used in confined spaces where the typical crane would never fit.

090 series cranes can be configured around obstacles, can be set-up on uneven ground, or operated in confined spaces like hallways and up against walls.

200 Series

This series of the Spydercrane is deemed the most versatile and is therefore popular among many industries, On of the most popular uses of this crane is as a glazing tool to set glass and other materials. Three models are available within this series that range in boom length from 24.9 ft – 28.4 ft and maximum lifting capacity of 5,800 lbs and 6,450 lbs. The geometric footprint of this model of the Spydercrane makes it suitable for use in hallways, balconies, or around obstacles.

All of the models within this series are equipped with the wireless radio remote control mentioned above, which frees the operator from being tethered to the crane.

300 Series

The 300 series Spyderceane is the perfect lifting solution for modern construction sites, as it’s a bit bigger than other models with an increased boom length of 47’10” and a maximum lifting capacity of 5,800 lbs and 6,680 lbs depending on the model.

Though it’s a larger ‘spyder’ when in use, it is only 52 inches wide when in travel mode, which will allow you to move it into any space through a standard double-door – And it’s zero-emission power options allow for use in indoor construction projects with low ventilation.

500 Series

The 500 series Spydercrane is perfect for steel erection as it offers a lifting capacity of up to 8,920 lbs and a boom length of 8.0 ft. The 500 series Spydercrane is revolutionizing how buildings are built with its heavy-lifting capacity and ability to perform in confined spaces.

This crane is also able to move through a standard double-door when in travel mode and can be used in job sites with low ventilation thanks to its zero-emission power options. And to top it all off, it comes mounted on a dual rubber track with a quick disassemble system that allows the outriggers, boom, and frame to be removed reducing the overall weight of the crane for transporting or hoisting.

700 Series

You may have sensed a theme and can guess that the 700 series Spydercrane is the largest Spydercrane currently available in the North American market. While it is described as a “beast” it still keeps the key feature of the Spydercrane in being compactable down to 5.48′ wide. The 700 Series Spydercrane can really do it all with a lifting capacity of over 6 tons.

Coming jam-packed with all of the features mentioned before throughout smaller series of the crane, the URW706 model has the ability to rotate 360 degrees in places, making it a dream to maneuver through confined spaces. You can find this tarantula level super Spyder crane being used in almost any industrial industry!

Crane Pre-Use Inspection Checklist | What to Look For

Crane Pre-Use Inspection Checklist: What to Look For

Crane Pre-Operation Inspection

When it comes to crane inspections, keeping up with them on the required inspection schedule should ALWAYS be the #1 priority.

According to the Canadian Standards Association, crane inspections should follow standards outlined by ISO (the International Organization for Standardization)—Specifically ISO 4309 and ISO 9927-1.

However, in-between those required inspections, it’s always a good idea to be proactive about your workplace safety and perform pre-operation inspections.

If your company provides it, always use and follow maintenance checklists that include critical safety components as specified by the manufacturer, professional engineer and/or your company’s requirements. The following list is based on information provided by the Canadian Centre of Occupational Health and Safety (CCOHS) and can serve as a good starting point in the creation of a company-specific checklist that suits your crane and any specialized hardware being used more effectively.

Crane Pre-Use Inspection Checklist: What to Check for During Pre-Operation Inspection

  • All capacity markings are present
  • All rope has no sign of kinks, cuts, breaks, corrosion, reduced diameter, broken strands of wires or other signs of wear or damage.
  • Rope drum cable is positioned correctly in the groove tracking and the means of anchoring is correct with no wear or damage.
  • Sheave ropes and guides are aligned correctly, and there’s no wear on the sheave groove.
  • All hooks are free of cracks, deformation, bent safety latches, broken springs or other signs of wear or damage.
  • You’re using the appropriate type of sling with legible and appropriate capacity ratings, with no holes, cuts, crushed wedding or other signs of damage.
  • All lights are working properly with none burnt out or broken.
  • Mechanical parts and guards aren’t loose, bent broken or missing.
  • Rails aren’t broken chipped or cracked.
  • No signs of wear on wheels (shown by bumpy riding).
  • Bearings aren’t loose or worn.
  • No signs of shoe wear on brakes.
  • Bridge bumpers and trolley end stops aren’t loose, missing or improperly placed.
  • Controller and collector shoes or bars aren’t worn, pitted, loose broken or in faulty operation.
  • All control buttons are labeled to indicate their function, are properly functioning and release immediately without sticking.
  • All boards, railings, and ladders in the foot walk zone are in appropriate condition.
  • All gears are properly lubricated with no presence of foreign materials in the gear teeth (indicated by grinding or squealing).
  • A fire extinguisher is present in the crane cab.
  • Before closing the main or emergency switch, ensure no one is on or around the crane – even when starting on regular duty.
  • Before closing the main switch, make sure that all controllers are in the “off” position.
  • Inspect oil after opening and locking out the main switch.
  • Make sure no overhead power lines are obstructing the crane operation.

 

Document these findings clearly in your maintenance logbook which should include all tests, repairs, modification, and maintenance. Keep this logbook with the crane and call upon certified professional inspection technicians and engineers as required. Never operate the crane if based on these findings it does not seem to be in safe working condition.

Crane Pre-Use Inspection Checklist: What to Inspect While the Crane is Moving

Before lifting any load with a crane, you should always inspect it while it is moving. During this inspection you should be looking out for:

  • Smooth play out of wire rope to and from a drum.
  • Sheaves are turning without binding or jerking as a rope passes over them.
  • Ropes are properly aligned where it enters the sheaves.
  • Ropes aren’t rubbing on the rope sheave guards.
  • No rubbing, scraping, or clattering noises during operation.
  • No jerky movements.
  • Controls and brakes are operating properly.

 

You should also test that the limit switch is working properly by slowly raising the hook block with no load attached to the hook.


When it doubt, always call upon the experts.

These pre-operation inspections should only be used as a way to stay on top of typical wear and tear that may lead to required maintenance.

Without inspections and maintenance, equipment failures can have a major effect on business costs, cause unscheduled outages and most importantly, could cause major and possibly deadly safety hazards. Hercules SLR offers crane certifications & LEEA-certified inspections, repairs, predictive & preventive maintenance (so you can pass those inspections!) and crane parts & accessories like wire rope slings, hoists & whatever else you need to lift.

Hercules SLR has qualified technicians to inspect and service all crane classes, specifically:

  • Overhead/Bridge Cranes

  • Economical transportation.

The LTM 11200-9.1 has been used to assemble larger portal cranes, radio towers, absorber columns, and wind power generators. When fully-loaded the base of the vehicle drives with slewing platforms, luffing cylinder and all four folding beams—With all of these elements, it will weigh in at over 100-tons. However, dismantling these elements is easy to do, making it so you only have to travel with what will be used on the job. Doing this can lessen the total weight to 34-tons, making it much more economical to transport.

2. PTC 200 DS PTC 200 DS crane

The PTC 200 DS is owned and operated by a company called Mammoet, located in the Netherlands. This crane is nearly 205 meters (675 feet) tall, has an attachment that can lift 3,500 tons at it’s max capacity and is so large that in order to weigh it down, 35 shipping containers (each 40 feet long) filled with sand are used as counterweights.

This heavy-lift crane has a maximum lift height of 140 meters (459 feet) and a radius of over 136 meters (446 feet). The PTC200 DS can handle a 2,000-ton load at a radius of up to 78 meters with 3,500 tonnes of ballast and 117 meters (383 feet) of boom—Or 58 (190 feet) meters radius on a 140-meter boom. It recently went through an upgrade that allows the crane to lift a 2,000-ton structure in one piece as opposed to lifting it in multiple sections.

The PTC 200 DS heavy-lift crane is used around the world mostly on large refinery and petrochemical projects. The crane was even used to construct the Dubai Observation Wheel, which is the world’s tallest Ferris wheel towering at nearly 213 meters (700 feet) tall. Other than this project, the crane has spent the majority of its life in the United States, South America and here in Canada!

3. The Asian Hercules IIIasian hercules lll 3 crane

The Asian Hercules is one of the world’s largest floating cranes, weighing in at a whopping 16,805-tons. The complete vessel features accommodations for 45 people! With a lifting capacity of 5,000-tons and a maximum lifting height of 120 meters (393 feet), this floating giant is designed for heavy lifting operations offshore.

The Asian Hercules III was constructed in 2015, registered in Singapore and has an ‘ABS A1, + AMS – Heavy Lift Vessel’ classification crane. Among its features, this crane operates with the following winches:

  • 2 cargo winches capable of pulling 20 tons at 10m/min.
  • 2 class anchor winches for handling the 6,975kg HHP bow anchor with a 76 mm grade 3 anchor chain.
  • 2 luffing winches providing a maximum luffing speed of 1.00m/min at full load.
  • 4 main hoisting winches for the A-frame, and 2 for the Jib, each capable of hoisting speeds of 2m/min at full load and 5m/min a light or no load.
  • 2 Jib adjustments winches, mounted on the A-frame, for adjustment of the job without load from 00 to 400 with respect to the A-frame.
  • 2 aux hoisting winches for the A-frame and 1 unit for the Jib, each capable of hoisting speeds of 10m/min at full load of 20 tons.

What’s the Jib? A jib or jib arm is the horizontal or near-horizontal beam used in many types of crane to support the load clear of the main support.

The construction of this mega-crane, designed by Gunnebo, is the culmination of more than 250-years of technical know-how. Designing the vessel required a 5000-ton modular block system with a spreader beam, luffing blocks, and sheaves. After two years of design and construction, the Asian Hercules III is a flexible lifting solution with interchangeable parts that can be customized for different lifting configurations.

4. SGC – 250 sgc-250 crane

The SGC – 250, the Sarens Giant Crane also known as ‘Big Carl’, is a 250,000t/m heavy crane designed to accommodate the heavy lifting requirements for refinery, oil and gas, mining, offshore platform, and third-generation components for nuclear power plants.

Built in 2015, this crane has a maximum lift capacity of 5,000-tons and features a 118m – 160.5m main boom configuration with a 40.5m – 99.5 m heavy-duty jib configuration. It operates on a 48.5m outer ring and requires a 5,200-ton counterweight. The jib can be extended up to 100 meters, giving it a maximum height of 250 meters (820 feet) and radius 275 meters (902 feet).

The SGC – 250 can operate on two different blocks at the same time—One on the main boom and one on the jib. The crane’s main hook block weighs 105 tonnes and has a safe working load (SWL) of 3,200 tonnes while the jib hook weighs 58 tonnes and has an SWL of 1,600 tonnes.

After it’s unveiling the SGC – 250 was transported to the UK where it was used on the Hinkley Point C nuclear power station construction project. Over the course of that project, the SGC lifted more than 600 pieces of pre-fabricated components.

5. SK10,000

SK10,000

Finishing up our list we have a crane that hasn’t yet hit the scene, but when it does, it will take the spot of the world’s largest land-based crane. The SK10,000, created by ALE, is set to be completed by Q4 of 2020.

As floating production storage and offloading (FPSO) units and floating liquefied natural gas (FLNG) units grow in popularity, larger cranes like the SK10,000 become necessary. Often times, modules of these ships are constructed elsewhere and then transferred to the shipyard for assembly. The SK10,000 will allow modules to be installed directly onto the ship’s hulls, advancing current capabilities in terms of both maximum weight lifted and impact on these project’s efficiency.

The SK10,000 will deliver unparalleled lifting capacity as well as a number of other features such as:

  • Jib outreach of up to 200m (655ft).
  • Ground bearing pressure below 25te/m2.
  • A winch hoisting system with various hook blocks to maximize lift capacity and hoisting speed.
  • A small plot area—The design will eliminate the need to install a full ring or crane track unless specifically required for the project, which will reduce the space needed to operate by 45%. This will be ideal for busy shipyards or areas with restricted access like oil refineries or petrochemical plants.
  • Reduced on-site disruption—The large lifting radius will allow the crane to be fully rigged and operated off-plot with less groud preparation needed.
  • Simplified logistics and assembly—ALE‘s specialists will be able to assemble the crane in a matter of weeks using standard plant and a crawler crane.

What’s a crawler crane? A crawler crane has its boom mounted on an undercarriage fitted with a set of crawler tracks that provide both stability and mobility. Crawler cranes range in lifting capacity from 40 to 3,500 short tons.

WHAT TYPES OF CRANES DOES HERCULES SLR SERVICE?
If you need overhead lifting device service or rentals, you’re in the right place. What kinds of cranes do we service? We service all crane classes, specifically: 

  • Overhead/Bridge Cranes
    • Top Running Overhead Crane
    • Under Running Overhead Crane
    • Modular Crane
  • Gantry Cranes
  • Tower Cranes
  • Rail Road Cranes
  • Floating Cranes
  • Aerial Cranes
  • Jib Crane

Have a type of crane you need serviced, but we didn’t cover it here? Give us a call—We service anything. 

HOW MUCH DOES CRANE INSPECTION COST?

We know, your top concern is probably price. “How much will this inspection, repair, preventive maintenance, etc. cost?” Unfortunately, this cost will likely vary depending on factors like what kind of service or part you need.

Specific costs will vary—Like we’ve covered in previous blogs, there are many different parts of a crane or types of service you might need, ranging from below-the-hook, repairs to the structural steel or inspections to the jib or other crane component.

  • Downtime: It can put a damper on productivity when a crane’s out of service, and the downtime associated an out-of-service crane with halting or pausing a project can be costly—Quickly, too.
  • Productivity: When inspections or tests are conducted by a competent/qualified person, they can identify issues and repairs can be scheduled during slower periods, so you don’t disrupt work and you know your crane is running reliably & smoothly during your business’ busy periods.
  • Peace-of-Mind: Know your equipment is running smoothly & ready-to-go, know if a repair or equipment replacement is cheaper and that your team is safe.

WHAT'S IN IT FOR ME?

We know, ‘preventive maintenance‘ might seem like a big waste of money for your organization. However, like mentioned above, preventive maintenance can actually reduce costs that eventually, can become even bigger repair costs.

  1. Reduce physical labour for employees.
  2. Meet project deadlines & stay on schedule.
  3. Cut-down on repair costs, prevent future damage and eliminate unforeseen equipment failure.
  4. Protect your investment.
  5. And finally, (the one you probably know), because you have to—It’s the law.

CRANE INSPECTION: WHERE, WHEN & HOW OFTEN?

CRANE INSPECTION: WHERE, WHEN & HOW OFTEN?

There are many different types of cranes, and your workplace will (should) have a robust inspection program plan in place for each type. Inspection frequency depends on a number of things, like:

  • How often the crane is used & when it’s being used,
  • Which Service Class the crane belongs to,
  • What it’s used for and what type of inspection is being done.

According to the Canadian Standards Association, crane inspections should follow standards outlined by ISO (the International Organization for Standardization)—Specifically ISO 4309 and ISO 9927-1.

Find it difficult to track this for your business? We know, and we listened. Receive crane service from Hercules SLR and gain access to our free asset management service, CertTracker.

What’s so good about CertTracker? 

  • Secure online database: Keep your entire operational asset history in one, secure place.
  • Alerts: CertTracker will notify management of failed inspections, repairs and work order details—It also tells you when you’re overdue for inspections and repairs.
  • Easy access: CertTracker uses RFID chips while handheld computers capture inspections & maintenance operations, which eliminates the need to manually enter data. It captures equipment when in & out of service, location transfers and all data is sent to the online database so you know exactly where it is, whenever you input it. If that’s not enough, it also converts units of measure instantly for easy use onsite.
  • Customization: Track what you need to track. Have your team or service provider record daily inspections, scheduled maintenance, annual inspections or other important dates. Each inspection is time-stamped by the user so your audit record is always accurate & reliable. Find specific assets by I.D. number, location, owner, etc.—Whatever you prefer.
  • Available 24/7: CertTracker is online and always open.
WHAT COULD GO WRONG? 

Inspections check for a number of issues. It’s important to have your crane serviced regularly—It becomes time-consuming, costly & ineffective to both operate and service the crane the longer you avoid proper inspections.

IN NEW BRUNSWICK, WE ALSO OFFER:

Hercules SLR in New Brunswick also manufactures gin wheels, or pulleys wheels. Gin wheels are a convenient, low-cost & economical way to raise and lower a load.

Hercules SLR in Moncton & Saint John, New Brunswick fabricates custom gin wheels, load-rated for use in refineries.

CM Guest Blog | The Twenty Year Rule

cm cranes and hoisting equipment

CM ON THE TWENTY YEAR RULE

CM knows it can be easy to fall into the ‘twenty year rule’ trap—but what is it? Read on for tips from Columbus McKinnon (CM) on why some rules actually are made to be broken. 

Their rigging experts discuss safety, inspections & why it’s important to keep your training up to date—No matter how long you’ve been doing it. 

While conducting our overhead lifting safety training it never fails that we get a comment to the effect of,

“We’ve been doing it this way for over twenty years. We never had an accident. And now, you’re telling me it’s wrong?” 

Just because you have been lifting a certain way for the past twenty years and never had an accident only means that you have been lucky. When performing safety training we emphasize all the safety standards and regulations that are applicable. They all serve a purpose.

When performing safety training we emphasize all the safety standards and regulations that are applicable. They all serve a purpose.

ANSI/ASME B30 Safety Standards for overhead lifting began in 1916 as an eight page safety code – now 94 years old. Although ASME is the American Society of Mechanical Engineers, many Canadian organizations and equipment used here observe their standards, so it’s worth noting. 

In Canada, the CSA standard B167.08 began in 1964—It’s 46 years old.

Finally, let us not forget OSHA, which began in 1970, making it 40 years old, who enforces two federal regulations for overhead lifting:  CFR 1910.179 for cranes and 1910.184 for slings. Between all these organizations and safety standards there is a total of 355 years of experience. 355 years trumps your 20 years, every time.

These organizations were not put together to make your life miserable! You can’t take short cuts the way you have been doing the past twenty years. These organizations include people that are involved in all facets of overhead lifting, including riggers and production and construction personnel that perform overhead lifting as part of their job. They want you to be safe in your work habits and environment so that you can go home at the end of your shift or work day to your family.

This blog post was written by Larry Lynn, former Product Trainer for Columbus McKinnon Corporation. 

CM | HOW MUCH IS ENOUGH WHEN IT COMES TO ANNUAL INSPECTION?

So, we know that standards for training, testing & inspections exist for a reason, and it’s important to keep your training and inspection knowledge up-to-date—CM explains more. 

CM was asked, “How do we complete the annual PM (preventative maintenance) per the manual unless we open up the gear box and inspect the internals?” This question is centered around the annual inspection task to inspect ‘Load Bearing Parts.'” 

Tom, a Technical Instructor who specializes in Hoists & Overhead Cranes for the Columbus McKinnon Corporation says: 

We encounter this question frequently in inspection and maintenance training classes. 

ASME Standard B30.16 defines load bearing / load suspension parts as follows; “the load suspension parts of the hoist are the means of suspension (hook or lug), the structure or housing that supports the drum or load sprocket, the drum or load sprocket, the rope or load chain, the sheaves or sprockets, and the load block or hook.”

Brakes, load and holding, gearing, motors, etc. are mechanical parts. They are part of the drive train.

ASME B30.16-2.1.3(b) states, “Covers and other items normally supplied to allow inspection of components should be opened or removed.”

ASME states that required inspection items be prefaced with “Evidence Of.” 

There are several indirect ways of checking for and detecting (finding “evidence of”) excessive wear or abnormal operation of internal parts. If gearbox oil is not degraded, there are no metallic particles attached to the drain plug, the hoist raises and lowers properly (with and without a load), and there are no strange or abnormal sounds from the gearbox, it is unlikely that serious problems exist. If this inspection causes suspicion, refer to ASME B30.16-2.1.3(c) “A designated person shall determine whether conditions found during inspection constitute a hazard and whether disassembly is required.”

Our Testing’s in the (Water) Bag | #TrainingTuesday

water bag testing with crane

WATER BAG TESTING AT HERCULES SLR

We’ve covered the importance of pre-use checks & inspections on the Hercules SLR blog before, like visual inspections, proof-testing and non-destructive testing – One thing we haven’t covered, however, is what water bag proof load testing is and why we do it here at Hercules SLR. 

So, to start—What’s a water bag, anyway?

Well, it’s a little less exciting than a water-ballon (only a little bit, promise) and is a method used to proof load test cranes that uses water instead of traditional, solid weights.  

There are quite a few benefits when you load test with a water bag versus traditional, solid weights. But what are they? In this article, we’ll cover:

  • What water bags are used to test for
  • The benefits of using water bags
  • Useful hardware for securing & rigging a water bag 
  • Safety tips 

WATER BAG TESTING | BENEFITS 

Water bags testing is for:

  • Cranes
  • Lifeboats
  • Elevators & conveyors 
  • Load-bearing structures & lifting equipment
  • Counterweights 
  • Bridges 

WATER BAG TESTING | BENEFITS 

What are the benefits of using water bags to test crane strength? Well, there is: 

  • If you’re close to a water supply. water bags: 
    • significantly reduce transportation costs, storage and handling issues 
    • rigging time
    • overall expense 
    • test load applied gradually and precisely 
    • problems identified and dealt with long before max. load is reached, and allows for safe controlled environment during testing conditions. 

Water bags are best used with spreader beams for offshore application. If you’re operating a crane or any piece of hoisting or lifting equipment, you must test it before using it for anything

A proof test is a test used to check the condition of any load-bearing structure. Often, during a proof test weight is applied beyond the working load limit to test how much strength a structure, like a crane, can truly take—This is important in case the crane is someday loaded beyond capacity. 

WATER BAG TESTING | HARDWARE 

So, what kind of equipment should you use with a water bag? Here’s some rigging equipment that might help you to secure the load: 

  • MasterLink  
  • Round Sling(s)
  • Shackles (Various or specific types of shackles may be required to secure the water bag—Check with manufacturing/provincial regulations to make sure your rigging complies). 
  • Lifting straps 

WATER BAG TESTING | SAFETY TIPS

  • Don’t load bags beyond the working load limit (WLL)
  • Use a calibrated monitoring device to measure the load of the water bag 
  • Remember, the water bag is considered the load, not lifting equipment & the lifting set for the water bag is separate—Keep this in mind when using water bags to test load-bearing structures. 
  • Optimal water bag design has a load carried by the web lifting set, not through the bag’s material. 
  • Be sure to perform a risk assessment before you test a crane or other load-bearing structure with water bags—There are instances that a water bag will fail, and riggers and nearby personnel must have a plan in place if failure occurs. 
  • Inspect water bags before each use 
  • Do not hang more than three water bags from a single attachment point

How we Make a HUGE Wire Rope Sling in Hamilton, Ontario

spools to make wire rope sling

HOW HERCULES SLR IN HAMILTON, ONTARIO MAKES A GIGANTIC WIRE ROPE SLING

What are we up to at Hercules SLR in Hamilton, Ontario? We’re making big things – a big wire rope sling, specifically.  

Check out these shots of Bryan Jarret, Production Supervisor and Adam making a sling for crane-use. It takes both of these guys just to hold it! 

So, how do Hercules SLR rigger’s make a sling this big? We’ll show you. 

WIRE ROPE SLING MAKING—WATCH HOW IT’S DONE

This is Bryan Jarret, our Production Supervisor at Hercules SLR in Hamilton, Ontario. Here, he’s pressing these huge lengths of wire rope to form a 6-foot eye on each end. 

This large sling will eventually be used on a crane for one of our clients’ here in Ontario. 

HOLDING A SLING IS A TWO-MAN JOB

rigging techs hold wire rope sling

 

 

 

 

 

 

 

 

 

A sling this size takes about 1-hour to splice. Each foot weighs about 15-20 pounds on its own. One technician holds the sling, while the other technician splices the opposite end. 

FORMING THE WIRE ROPE SLING EYE

A wire rope this size has a WLL of 76,000lbs. If these two rigging technicians were standing on top of one another, the sling would still be taller than both of them! 

BIG WIRE ROPE SLINGS NEED BIG MUSCLE

Here, they complete the pressing/swaging process on the other side. As the wire rope strands become tighter, the technicians must manually bend through the eye, which takes a lot of arm-strength!  

There you have it, folks—Here’s how our riggers make a sling that lifts BIG things.
