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

Crane Equipment: Chains, Cranes & Automobiles?!

Cranes have been used since the first century – in that time, they were powered by humans or animals to lift heavy loads. Cranes have adapted and come a long way since – they now use an assortment of crane equipment and hardware to lift, lower and even sometimes move horizontally.

Read on to learn more about the modern variety of crane equipment available and Hercules SLR’s tips for using it.

CRANE EQUIPMENT: an overview

For rigging with cranes, different types of lifting equipment (also known as tackle) are used. These include:

  • Wire Rope Slings
  • Synthetic Slings
  • Shackles
  • Snatch Blocks
  • Hooks
  • Chain Hoists
  • Chain Pullers
  • Eye Bolts
  • Tirfors
  • Jacks
  • Lifting Beam
  • Spreader Beams
  • Beam Clamps
  • Plate Clamps

CRANE EQUIPMENT: wire rope slings

Pay special attention to wire rope slings as they are susceptible to servere wear, abrasion, impact loading, crushing, kinking and overloading – small changes in the slings’ angle affect the safe working load of the sling. Care should be taken around rough edges and wire rope slings – even an edge you might not consider ‘sharp’ can make considerable damage to your wire rope sling, making it unsafe and ineffective. Use sleeves, wear pads or corner protectors to protect your wire rope sling from damage.

Be sure to not drop a load or run a load over the sling – this will crush the sling. Also, don’t stop and start suddenly while you lift and lower with a wire rope sling, as this increases the slings’ stresses and increases possible failures.















There are three ways to identify wire rope slings: the SWL, I.D. number and certificate number.

  1. Hard-stamped on ferrule
  2. A tag which has a wire running through the tag and eye of the sling
  3. Large metal washer where the wire of the sling is passed through when you make the eye of a sling


There are three main wire rope sling configurations:

  1. Double-Choker Hitch
  2. Pair of Double Wrap Chokers
  3. Single Choker Hitch

Round slings’ are versatile – they’re strong, yet delicate to the load to lift. They’re light, flexible in many directions and malleable which is especially helpful when lifting an awkward or delicate load.

Synthetic Round Sling Label

CRANE EQUIPMENT: synthetic round slings 

Round slings’ are not easily damaged by sunlight, humidity, grease, dirt or seawater. Round slings’ are identified by the colour of the label, and also have the SWL on it.

CRANE EQUIPMENT: web slings 

Web slings are suited for particularly those that can be easily damaged. They’re easy to damage if you use them improperly – your web sling shouldn’t touch a sharp edge, heat or chemicals that will cause damage.



For crane lifting, two different shackles are typically used – bow and d-shackles. When using synthetic slings with a crane, two types of shackles are available, wide sling shackle and a round sling shackle. Web sling shackles are wider and bow out in the middle, and round sling shackles are narrow and sometimes have small valleys in the shackle bow, which supports the synthetic strands better.

These prevent the sling from bunching and pinching, which can be an issue with bow or d-shackles – it also reduces the SWL capacity of the sling.

To use shackles for crane lifting safely, follow these tips:

  • Don’t replace the shackle pin with a bolt – only the proper fitted pin should be used. Bolts aren’t meant to take the bend that a pin can handle.
  • Pins must be straight and all-screw pins must be completely seated
  • Cotter pins should be used with all round pin shackles
  • Shackles worn at the crown or pin by over 10% of original diameter should be removed from service and destroyed.
  • Don’t pull your shackle at an angle with a sling or hoist rope – this reduces the shackle’s capacity by 50%. Spacers can be used to centralize the load on the pins with spacers.
  • Don’t use screw pin shackles if the load can roll under load and unscrew


A sheave block is a single, or multi-sheave block which opens on one side – this opening allows a rope to be pulled over the sheave and eliminates the need to be threaded through the block. When crane lifting with wire rope, sheave blocks can be purchased with configurations for hook, shackle, eye and swivel fittings.

  • Sheave blocks are normally used when it’s necessary to change the direction of pull on the line. When this happens, the stress on the sheave block is significantly greater than the angle between the lead and load lines. 
    crane equipment, rigging services, hercules slr, Crane Equipment: cranes, chains & automobiles
    Pulley with a sheave on a mobile lifting crane, with 25-ton lifting capability
  • When the lines are parallel, 1000lbs on the lead line results in double the weight on the block—2000lbs on block, hook and whatever the connection points are attached to. As the angle between lines increases, the stress on the block and hook is reduced.


Many different hooks are available for lifting and rigging operations – check with manufacturer instructions and warnings before using in a crane application.

When using hooks to lift with a crane, follow these tips:

  • Ensure hoisting hooks are fitted with safety latches (except grab and sorting hooks)
  • Inspect hooks often, looking for wear in the hook’s saddle – check for cracks, corrosion and if the hook’s body is twisted.
  • Inspect the shackle’s throat opening – if the hook’s been overloaded or is weak, the throat will open. If this is the case, remove from service and destroy so no one else attempts to use it.
  • Inspect for cracks in the hook’s saddle and neck
  • Be sure the hook is stamped with its SWL
  • Note that the SWL applies when the load is in the saddle of the hook, as this reduces the SWL.


Turnbuckles are sometimes called rigging screws and can be supplied with eye end, jaw end, stub end fittings and/or a combination of these.

  • Use turnbuckles fabricated from alloy steel with weldless construction.
  • If turnbuckles have end fittings, ensure hooks are fit with safety latches.


Chain hoists are often used with cranes to move larger equipment and machinery. Chain hoists vary in size and length, and require little effort to execute a lift.

Chain hoists are durable, but can be damaged easily. To prevent damage, check:

  • The SWL is right for the application/load
  • The chain hoist has been inspected or certified by a third party
  • The hoist’s body is free of cracks or broken castings
  • The hook isn’t deformed and is fit with a safety latch
  • Anchor pins are in place correctly, and are the right type
  • Chain is in good working condition
  • SWL is clearly marked on the chain hoist block

A lever hoist is similar to a chain hoist, but operates slightly different with a lever to lift and lower the load – it can also be used to pull loads.


When lifting with a crane and eye bolts, ensure eye and ring bolts are made of alloy steel and have shoulders or collars.

Do not load eye bolts at an angle – angular loading reduces the weight of the load they can safely support.


A tirfor is a mechanical device, equipped with a level handle to operate. They’re used to pull and add tension, and can also be used to lift if they have blocks.
