7 Common Misuses Of Fall Protection Equipment

Every worker has the right to return home safe each and every day. The most recent report conducted by the Canadian Centre for Occupational Health and Safety (CCOHS), showed that 251,508 Canadian’s accepted claims for lost time due to work-related injury or disease in just one year.

Did you know that approximately 18% of those time-loss injuries, or about 42,000 workers a year, are injured due to fall incidents alone? You can prevent falls and incidents like these by wearing proper fall protection equipment, and wearing it right.

If you’re working at a height exceeding 3 meters (10 feet) occupational health and safety laws generally require fall protection measures to be in place. You can check with your jurisdiction as requirements do vary, but in most cases fall protection measures such as fixed barriers, surface opening protections, control zones, fall or travel restraint systems, fall containment systems or fall arrest systems are required. You can learn more about some of these systems by reading our fall protection glossary.

But it’s not good enough just to throw on the required minimum fall protection equipment and call it a day – It’s important the equipment be used properly.

In this blog, we will be talking a bit about 7 common misuses of fall protection equipment, to serve as a reminder for things to look out for, but should be used in conjunction with proper training. The Hercules Training Academy offers an extensive suite of high-quality safety training and certification courses, including a course on fall protection!

1. Misuse of Rebar Snap Hooksfall protection repair snap hooks

Rebar hooks (also referred to as pelican hooks, large gates or form hooks) are frequently used pieces of equipment in the fall protection world because their large openings make them quick and easy to use. They also allow for connection to many objects, eliminating the need for additional anchorage connectors. However, not using an additional connector can be very dangerous in the wrong circumstances and rebar hooks are only approved for specific configurations so if you use them outside of those configurations, it can present a safety hazard to workers.

The best way to mitigate the misuse of rebar snap hooks is to ensure that the anchorage connector D-ring is larger than the snap hook to avoid side loading. Since this is difficult to achieve, oftentimes workers choose to use a small anchor strap instead with some workplaces not allowing the use of snap hooks all together!

2. Misuse of Lanyards

A common mistake made with lanyards is users wrapping them back upon themselves. Most fall arrest lanyards are not designed to wrap around a structure and hook onto themselves, but a worker may try to set it up in that way if no other anchorage point is available. This can cause equipment failure due to damaged to the lanyard material or improper gate loading. This problem can be solved with anchorage straps, which are designed to be wrapped back on themselves – providing the proper strength needed to be safe while also remaining accessible.

Furthermore, regardless of if a lanyard is designed for wrapping around beams, piping, ductwork, or around a guardrail, with time, the sawing action could damage it. This problem can be mitigated by using a beam clamp or beam straps as an anchorage connector.

3. Inappropriate Anchorage Connection or Strength

A fall protection system is only as effective as its anchorage. Always ensure the anchorage is strong enough to support the weight of the individual wearing it in the case of a fall. To be sure you can rely on your fall protection equipment, always test the strength of the connection after set up.

To be certain you have the right anchorage strength, only use certified anchorages and make sure there is always someone on the scene with the correct training to properly identify the appropriate anchorage to use for the circumstances of the job. Since the average weight of the individuals using the fall protection system will very, the anchorage system must be designed for the maximum weight of any potential users.

4. Anchoring Below The Dorsal D-Ring

Another common misuse of fall protection systems is workers anchoring themselves to a point below their dorsal D-Ring (sometimes even below their feet). This increases the free fall weight and distance, sometimes beyond the equipment’s ability to arrest it. Pushing these limits can cause the lanyard or anchorage to fall, or can exceed the allowable force on the body, which can increase the likelihood of a serious injury.

The goal is always to minimize free-fall distances, so connecting to a point above the dorsal D-ring should be the choice if in any way possible. However, if there is no overhead structure to provide an anchorage point, the worker must use a free-fall lanyard that is approved for the greater free-fall distance and force.

5. Unproperly Adjusted Harnesses

For fall protection equipment to be used correctly and effectively, workers must be wearing their equipment correctly. Most fall protection harnesses are designed with adjustable leg, waist, shoulder, and chest straps, which all must be sized to the user. A fall protection system is no good if you can’t stay in it, which is exactly the risk presented if the harness is not tightened properly to the user’s body. As you can imagine, being ejected from a harness mid-fall can lead to serious injury.

Here’s what to look for to ensure a harness is fitted correctly:

  • The dorsal D-ring sits between the worker’s shoulders blades – If it’s adjusted too high, the metal hardware could cause injury to the user’s head and if it’s adjusted too low, the user can be left hanging in a poor position with an increased risk of suspension trauma.
  • The chest strap should lie across the user’s chest at the base of the sternum – If it’s too high on the user’s chest, it can cause a choking hazard in the case of a fall by putting pressure on the user’s neck.
  • Shoulder straps cannot be pulled off of the user’s shoulders or outward.
  • Sub-pelvic straps are positioned under the buttocks.
  • Leg straps are tightened to a point where four fingers can fit between the strap and the user’s leg, but cannot pull away from the leg.
  • General observation of harness fit – Looking for things like twisted straps or asymmetrical leg straps.

6. Using Damaged or Recalled Equipment

Everything from UV exposer, corrosion, wear and tear and everything in between can impact the effectiveness of your fall protection equipment. You can avoid UV and corrosion damage by storing your equipment properly when not in use, but some amount of wear and tear cannot be avoided if you’re actually using your equipment, which is what it’s made for after all! Because of this, all users should be trained on what to look for when inspecting equipment to ensure that it is in proper working order to operate safely.

Steps to ensure your equipment is always in safe working condition:

  1. Have your equipment inspected on at least an annual basis – Another thing Hercules SLR’s experienced and LEEA certified team can take off your hands! 
  2. Register your equipment so you are always notified of product recalls or advisories.
  3. Stay current on advisories and advances in technology.
  4. Store equipment in an environment that is as protected as possible.

7. Confusing Twin-Leg Energy-Absorbing & Self-Retracting Devices

Although these two devices sometimes look and function similar, a common mistake people make is thinking twin-leg energy absorbing & self-retracting lifeline devices are the same or interchangeable. However, since they are designed and tested for specific conditions, it’s important they are used for those appropriate applications.

The self-retracting lifeline (SRL) vs. energy-absorbing lifeline (EAL) is a topic of lively debate among fall protection engineers because both devices have their benefits but the general consensus is that an SRL is preferable in an industrial environment where an overhead horizontal system is (or can be) installed and an EAL is preferable in a construction environment where workers typically do not have access to an overhead anchorage point.

Product Spotlight | Crosby Forged Sorting Hooks

Product Spotlight: Crosby Forged Sorting Hooks

Today, the Hercules SLR product spotlight is on Crosby forged sorting hooks. While sorting hooks may not be a piece of rigging equipment the everyday rigger reaches for every day, they are extremely handy when put to use in their intended capacity.

Sorting hooks are manufactured for use in sorting and laying out plates, pipes, cylindrical or tube shapes and other items that allow the full depth of the hook throat to be engaged. They are always used in multiple sling leg applications, in order to balance the load by engaging it on multiple ends.

Although many hooks used in overhead lifting are required to be equipped with a latch, sorting hooks are one of the few types of hooks designed not to use a latch as it would limit the practical use of the hook when lifting plates and cylindrical loads where full throat engagement of the hook is required.

Sorting hooks should be used at a 30° to 45° angle to get full engagement. Since the equipment functionally relies on its long throat being fully engaged, if you fail to do this, it will result in a significant reduction to the working load limit (WLL) of the hook. With this being said, you never want to concentrate your load on the last two inches of the hook tip, as this too would mean the full throat of the hook would not be properly engaged – and that section of the equipment is not made to support significate weight as it tapers off to being much thinner then the weight baring sections of the hook.

Crosby Forged Sorting Hooks are made of forged alloy steel that’s both quenched and tempered. One of Crosby’s many key attributes in that they full-cycle quench and temper heat treatment all of their equipment. In order to properly transform the microstructure of drop forgings (fancy right?!) products are re-heated after forging, then quenched and tempered* using tightly controlled processes and equipment. This heat treatment provides consistent temperature control and results in superior material properties.

*But what in the world is quenching and tempering? The process of quenching or “quench hardening” involves heating the material and then rapidly cooling it to set the components into place as quickly as possible. Tempering is achieved by heating the quenched material below the critical point for a set period of time, then allowing it to cool in still air.

10 Tips From Crosby to Keep In Mind When Using Sorting Hooks

  1. The sorting and laying out process includes moving these materials at a height close to the ground with the load and load connections visually observable by the crane operator throughout the entire load handling activity.
  2. The hooks must be attached in a manner that will maintain a level, balanced and stable condition throughout the entire process.
  3. If the load exhibits obvious bending, the lift must then be immediately stopped for analysis and evaluation to ensure safety.
  4. During the load handling activity, the slings with hooks at the load connections must remain under tension at all times to prevent any of the hooks from disengaging.
  5. Never concentrate loading on the last 2 inches of the hook tip.
  6. Never exceed 45 degrees “included angle” between two sling legs that are on the same side of the load. Exceeding 45 degrees may result in the slings slipping along the load surface.
  7. The recommended angle of loading when using sorting hooks is 30 to 45 degrees. These lower angles, although typically discouraged for most rigging applications, allows the load to more easily obtain full hook throat engagement. When the angle of loading is greater than 45 degrees, tip loading and failure to obtain full hook throat engagement is very much a concern.
  8. Sorting hooks are for straight in-line loading only. Sideloading applications are not allowed.
  9. Calculate the sling tension and know the loading in all connection points to ensure all rigging gear is sized appropriately.
  10. Never exceed the working load limit as stated on the sling identification tag. Remember, sorting hooks are used in multiples, such as two-, three-, or four-leg wire rope sling assemblies. All slings require proper identification including the capacity of the sling assembly.

Bonus Tip!

The real Pelican Hook

Sorting hooks are known as many things, such as lay out hooks, shake out hooks or pelican hooks. Though, if you refer to them as pelican hooks, be sure the person you’re speaking with truly knows what you mean because there is actually a different type of hook used in nautical and marine applications that’s really called a pelican hook. The real pelican hook is meant for securing ship anchors, life raft canisters or cargo gear and they are not rated to perform overhead lifts.

Pssstt…If you’re looking for an actual pelican hook, head on over to Hercules SLR’s sister company, Spartan Marine! Spartan Marine is your source for high-quality marine products and services, offering a wide range of solutions to those with industrial, commercial and recreational marine interests.

Product Spotlight: YOKE Swivel Self-Locking Hooks

yoke swivel self-locking hooks blog header

Product Spotlight: YOKE Rigging Hardware 

Concerned about price, quality & reliability? Choose YOKE, and get all three without making a sacrifice. YOKE swivels are manufactured with the highest grade materials, and are zinc-plated for corrosion resistance and a long life.

WHY USE SWIVEL HOOKS?

Swivel hooks come in two varieties. These are:

  • Positioning Hooks allow the rigger to align the hook while connecting to the load. These hooks aren’t meant to rotate while under load, only to position the hook to the pick point.
  • True Swivel Hooks with Bushings allow the hook to rotate freely under the load, while the top coupling/fitting pivots to let the load rotate. This helps prevents your line twisting.

Swivels should be used when the lift deals with these issues:

  • Swivels reduce bending loads on rigging attachments to allow the load to position itself freely.
  • Swivels should be used in place of shackles during applications where the shackle might twist and might be haphazardly loaded.

FYI: Before you lift a load, make sure there are not cracks or defects in the hook or latch, and that the chain or wire rope is not worn, and in good working order. Not all hooks are meant to overhead lift and not all swivels are meant to swivel under-load—It’s important to know which application the one you use is meant for.

YOKE SWIVEL SELF-LOCKING HOOKS yoke sorting hooks

Today, the Hercules SLR product spotlight is on YOKE Swivel Self-Locking Hooks and some of the lifting products from them we like the best. Read on to learn more about YOKE Swivel Self-Locking Hook specifications, tips for use and which applications to use swivel self-locking hooks for.

Get Hooked: All About Clevis Grab & Slip Hooks, Eye Hooks & More 

We’re hooked on hooks at Hercules SLR!

There are many different hooks used for towing, pulling, securing, lifting and rigging, and each type of hook comes with different openings, latches, sizes and more. Hooks are often used to create sling assemblies (particularly with chain), and are also used in various transport applications.

It can be difficult to remember them and what they’re used for, so Hercules SLR wants to make it easy—We’ve made this comprehensive hook guide to secure your hook know-all.

This hook guide will cover topics like what is a below-the-hook lifting device, some of the most often-used hooks for securing and rigging, including non-overhead hooks, overhead lifting hooks, transportation hooks, what the different hook & chain ‘grades’ mean, plus tips for maintenance, inspection, ASME hook standards, and more.

Ready to get hooked on rigging? Read on! 

What Exactly is a Below-the-Hook Lifting Device?

A below-the-hook lifting device is ‘any device used to connect a load to a hoist. The device may contain components such as slings, hooks, and rigging hardware…” A below-the-hook lifting device is a piece of equipment connected to a crane or other lifting device which grabs an item so it can be moved or secured to different place.

To that end, you might think that cranes and other lifting decides are known as “above-the-hook” lifting devices, however, they’re more often referred to as ‘overhead lifting devices’, and are rarely referred to as above-the-hook.

Clevis & Eye Hooks: What’s the Difference?

A clevis hook refers to a hook with a U-shaped attachment point or coupling with holes to thread a pin through and assemble your rigging—Many people like the removable pin to assemble and disassemble rigging quickly & easily. Clevis hooks are used for non-overhead applications.

You’ll likely hear the term ‘clevis’ used to describe other metal pieces of hardware with a clevis coupling. Hooks with clevis attachments can also be used for overhead lifts in many cases (Remember, they’ll be marked as Grade 80 or higher).

An eye hook (non-cradle grab & slip hook) is also used for non-overhead lifts, and is often used with tie-down equipment.

So, what’s the difference between eye hooks and clevis hooks? The attachment point/coupling. An eye hook has a rounded attachment point/coupling, unlike a clevis hook, which comes with a cotter pin to thread through the hole. Both can be used for overhead lifting, but are also often found alongside transportation securing and rigging set-ups.

Non-Overhead Lifting

Transportation 

Grade 70 chain and hooks are typically used to secure loads for transportation applications. Grade 80 is being used more often, however Grade 70 continues to be a popular choice for securement.

Overhead Lifting

Securing, Lifting & Rigging

Rigging hardware is used to attach a load to the lifting point of a crane, and hooks are among some of the most popular rigging hardware.

EYE HOOK

  • There can be different kinds of eye hooks—Hooks typically are eye or clevis hooks, which refers to the hook’s point of attachment.

CLEVIS HOOK

  • A hook with a clevis coupling or attachment point (see above).

SWIVEL HOOK

  • A hook with a swiveling coupling or attachment point.

EYE/ EYE HOIST HOOK

  • Available in both carbon and alloy steel.

FOUNDRY HOOK

  • A foundry hook is a type of grab hook.

GRAB HOOK

  • A grab hook does not usually feature a safety latch. It’s important to note that like clevis and grab hooks, other types of hooks can be grab hooks. For example, foundry hooks are a type of grab hook.

SLIP HOOK

  • A slip hook has a wider throat than a grab hook, and does feature a safety latch.*

SORTING HOOKS

  • Sorting hooks have wide throat openings, which taper to a narrower basket. They have a slightly sharper tip than other hooks, and are used to quickly grab objects to lift. These are normally used in pairs, on steep angles.

* Safety latches are used to make sure the load stays connected under slack conditions. They’re not load-rated, and should never be placed under a Herculesload. Use hook latches unless unsafe to do so.

Hook Maintenance

When Should a Hook be Removed from Service?

According to ASME B30.10 standards, hooks should be removed from service when they are:

  • Missing/illegible hook manufacturer’s identification or secondary identification
  • Missing and/or illegible rated load identification
  • Excessive pitting or corrosion
  • Cracks, damage and/or gouges
  • Any wear that exceeds 10% (or as recommended by the manufacturer) of the original section dimension of the hook or its load pin
  • Any visible deformations—This includes any bends, twists or other abnormalities from the plane of the unbent hook
  • Any distortion that causes an increase in the throat opening of 5%, not to exceed 1/4″ (6mm), or as recommended by the manufacturer.
  •  Inability to lock or latch—If a hook has a safety latch, it must be able to close properly, or any self-locking hook that doesn’t lock.
  • Damage, missing or malfunctioning hook attachment and securing means

Hooks should be inspected before, during and after use by the user. Rigging hooks should also be inspected periodically, or as recommended by the manufacturer.

Non-destructive testing is often used to determine if there are defects, nicks, gouges or any other deformations in metal gear or hardware, like hooks.

Grade 70, 80, 100—What do they all mean?

When we talk about ‘grade’ in relation to hooks, we actually refer to the grade of the chain that will be used with the hook. Grade refers to the tensile or breaking strength of chain.

Sound good? Let’s get into it:

GRADE 70
Grade 70 chain
Grade 70 Chain.

NAME: Grade 70

PROPERTIES: Heat-treated carbon chain

INDUSTRIES: Transportation

APPLICATIONS: Use as a tie-down chain or transportation lashing.

DON’T DO THIS: Grade 70 chain is not meant for overhead lifting—Only use Grade 70 chain and hooks for tie-down and lashing applications.

FUN FACTS: You’ll likely hear Grade 70 chain called ‘trucker’s chain’. It usually has a gold-chromate coating that helps it resist corrosion, since their load is continuously exposed to the outdoor elements and things like salt from the highway also reduce their effectiveness. The gold colour also helps it remain visible for truckers.


GRADE 80

NAME: Grade 80

PROPERTIES: Heat-treated steel chain

INDUSTRIES: Rigging, material handling & some transportation.

APPLICATIONS: Grade 80 chain is the minimum grade for overhead lifts, and is also often used in applications like recovery, safety & towing. Grade 80 chain is also often used with hooks in transport for flat-bed trucking to secure heavy loads.

DON’T DO THIS: Don’t use Grade 80 chain and hooks that are specifically marked for tie-down application in an overhead lifting capacity. (Hercules SLR’s Overhead Lifting Chain is meant for overhead lifting applications).

FUN FACTS: Will have 8 or 800 to denote that it is a Grade 100 chain or hook. 


GRADE 100  

NAME: Grade 100

PROPERTIES: Alloy-steel chain

INDUSTRIES: Rigging & lifting—Mining, offshore, construction, material handling & maritime

APPLICATIONS: Sling component, popular for overhead lifts.

DON’T DO THIS: Use any hook to rig with—Use at least a Grade 100 hook with chain.

FUN FACTS: Will have 10 or 100 to denote that it is a Grade 100 chain or hook.


The More you Know

  • These are some of the most commonly-found hooks in rigging—Some unconventional, or less-commonly found hooks include foundry, claw, bucket, ‘S’ hooks, alloy-swivel, plate & sorting hooks. 
  • Lifting hooks are constructed with a minimum 5:1 safety factor.
  • Hooks should have a latch, or safety latch to connect the throat opening. This prevents load lines from disconnecting. Some overhead lifting devices may not have a safety latch or may have additional features that make using the latch impractical.
  • NDT or non-destructive testing is a good way to check for deformities and defects in metal gear like hooks. We can find abnormalities on the inside and the outside of your metal gear.
  • The load hook should be the weakest part of the lifting equipment.
  • The hook tip should point out, away from the load, with no slack present so the hook won’t tip-load.

TAKE THE CROSBY QUIZ

So you think you know how to inspect a hoist hook? Prove it. Take the Crosby Quiz and find out if you’re a  pro at inspecting hooks for hoisting, or if you should get some more training. 

It’s important to know what makes a hook no longer safe to use – there are a number of factors that contribute to this, and aren’t always glaringly obvious like it being broken or crooked.

Hooks that don’t pass inspection can cause the load to release, and this can result in damaged materials, injured workers or legal consequences. It’s important to conduct inspections before you use the sling – each time

Take the Quiz from Crosby and find out if you’re a hook inspection pro, or if you have a bit more to learn.

Crane Operator Crushed Between Two Steel Frames When Rigging Failed

The operator of an overhead crane had been using a chain sling attached to the hook of the crane, and was setting it up into a single choker hitch to pick up and turn over the steel frame, that was lying horizontally on two sawhorses. The hook on the sling did not have a safety latch. The operator was standing between the load and another steel frame that was leaning vertically against the shop platform. The chain disconnected from the hook and the vertical steel frame fell towards him. He was crushed between the two steel frames. [Source: OSHA Case Histories – Rigging Accidents- Case History #7]

Possible ways to prevent this type of accident:

  • Ensure that workers do not place any part of their bodies into areas where they might become trapped when operating an overhead crane.
  • Ensure that the tools and equipment used are regularly inspected for defects and are replaced or repaired as needed.
  • Ensure that workers who use cranes are trained in rigging procedures.
  • Perform daily inspection of cranes using safety checklists to ensure that all equipment is working properly.
  • Ensure that the hook has a working safety latchand if not, is moused.

Invest in tomorrow by practicing safety today! There are several organizations that are dedicated to maintaining and progressing safety standards. ASME has sustained safety standards for the Crane, Rigging, and Lifting industry. One of the most frequently referenced standards is ASME’s B30 Safety Standard for Cableways, Cranes, Derricks, Hoists, Hooks, Jacks, and Slings.

ASME B30 is referenced throughout Crosby literature and training material. The many volumes cover a wide variety of topics, but there is a consistency to the guidance offered. For example, latches are discussed repeatedly appearing in B30.2 (Overhead Cranes), B30.5 (Mobile Cranes), B30.10 (Hooks), B30.23 (Personnel Lifting), and others.

When it comes to the use of latches, B30.16 (Overhead Hoists) summarizes it perfectly:
“Hooks shall be equipped with latches unless use of the latch creates a hazardous condition.”

Rope & Sling (RSS) Donates Rigging Gear for Boat Lift

RSS-boatlift

Rope and Sling Specialists Ltd. (RSS) UK donated lifting and rigging gear to the Shadwell Basin Outdoor Activity Centre in East London as the charity had a requirement to lift a 2.5t rescue support boat out of the River Thames onto land for maintenance and repair.

The activity centre is located next to the King Edward Memorial Park Foreshore (Wapping) site of the Thames Tideway Tunnel project, a major new sewer. RSS is a frequent visitor to the area, providing lifting equipment and periodic Lifting Operations and Lifting Equipment Regulations (LOLER) inspections for the site, made up of the foreshore of the tidal Thames River next to King Edward Memorial Park and an area to the south.

The activity centre provides watersports and adventurous activities, including training courses, events, and sessions for groups, schools, and individuals throughout the year. It approached Tideway officials to ask for their help to lift a boat out of the water and back again once repairs were completed. To experienced lifting professionals the project was routine, but the charity wouldn’t have been able to execute it alone.

Graham Dawson, depot manager at RSS’s Aylesford facility, said: “When I heard about the centre’s requirement I had no hesitation in offering them our equipment free of charge. We spend a lot of time at the site and were able to time delivery with a three-week-long LOLER inspection, led by Steve Conroy, that we complete every three months. It was a great opportunity to combine important safety-related work with supporting a good community cause.”

RSS supplied two MOD 6 spreader beams at 2.5m and two 10t capacity, 12m-long duplex webbing boat slings. The boat was 7m long and 2.5m wide; a canoeist and slinger combined to pass the slings underneath the vessel whilst in the water before a three-axle Liebherr mobile crane, kindly donated by Emerson Crane Hire, already rigged with the top slings, raised it from the water.

Simon Steane, lifting operations manager for Tideway East, the section of the super sewer that runs from Chambers Wharf in Bermondsey to Abbey Mills, near Stratford, said: “Everyone involved was very happy to help the Shadwell Basin Outdoor Activity Centre with their boat lift. We use RSS for their fast response time, professionalism, and flexibility.”

Mike Wardle, centre director at the Shadwell Basin Outdoor Activity Centre, said: “Our assets like our safety boat enable us to have larger numbers of people accessing the river safely. We particularly target young people from low economic backgrounds and young people with disabilities. We also give young people a pathway to employment in sports coaching through our youth project. We raise funding to deliver the activities from grant giving bodies, organisations, business, and donations.”

He added: “Any company that assists us with their technical and professional skills is worth their weight in gold and for the staff and volunteers that impart their time at the charity a source of relief. The safety boat is now in dry dock and is undergoing repairs to the pro shaft as well as a deserved major service. A massive thank you to all who have helped our community!”

Crane Work Wraps Up at New Winnipeg Towers

Crane Winnipeg
Huge Liebherr mobile crane may have been tallest ever seen in city
In May, the skyline of downtown Winnipeg was changed significantly with the removal of the last tower crane on site at True North Square. Phase 1 of the project, involving Tower 1 at 242 Hargrave and Tower 2 at 225 Carlton, began in January 2016. The substantial construction effort required significant crane work, with construction handled by PCL Constructors Canada Inc. and the dismantling subcontracted to Sterling Crane.

“Tower 1 topped off its structural building form in December 2017, reaching its final height of 17 storeys, and subsequently its tower crane was removed in January 2018,” says True North Real Estate Development president Jim Ludlow. “Tower 2 topped off in March 2018 at 25 storeys and its tower crane was removed in May 2018. These milestones have had a visible impact on the skyline of downtown Winnipeg, so they have been very exciting and rewarding to observe as we progress towards a new cityscape.”PCL project manager David Enns says his company was responsible for the cast-in-place concrete structure on both towers. This involved supplying the concrete, the placing of concrete and rebar, form work, concrete pumping, and the installation of precast stairs and landings, and other material handling. For much of the heavy lifting, PCL utilized two cranes – a Liebherr 316 ECB12 and a Liebherr 316 ECH12.

“They were the best choices mostly because of the overlapping coverage,” Enns explains. “When we sized them, we made sure that it could accommodate the form work systems that we wanted to use. It was based on them working in conjunction with each other with the overlap in height and the jacking sequences, including how they would tie into the structure in order to be efficient.”

The way the cranes were staged required them to be tied into the structure, once the structure progressed past a certain height. When PCL began work on Tower 1, the timing of the construction of Tower 2 was not yet known for certain. In order to ensure that there was sufficient coverage for the full site, both tower cranes were tied to Tower 1.

“Both were top climbing tower cranes,” Enns says. “The biggest reason for that is because of the limited real estate that we had. We couldn’t afford to bring in big mobile cranes every time we needed to jack the cranes up as the structures progressed. They were able to climb themselves up, and then when we were done, they had the ability to climb themselves down prior to full dismantle.”

Preparation for the selection of tower cranes involved a detailed review to ensure the cranes had the right capacities to accommodate the required lifts and the size of the flyer cables, core forms and gang forms. They also had to reinforce the foundation walls around the tower cranes to prepare for the mobile crane load imposed on the structure during the dismantling of the tower cranes.

Crane-Winnipeg“It’s pretty common to see tower cranes with a couple of precast piles under the foundation, but for our tower cranes, our foundations were cast-in-place concrete raft slabs, with four caissons a piece to support them because they were freestanding fairly high right off the bat,” says Enns.

The key challenge for this job was limited space – city roads and the St. Mary’s Church bound PCL on three sides. With limited room to maneuver or stage materials, there was a constant focus on scheduling and sequencing to make sure that they had material delivered as needed.

“Otherwise, not only would the site get overrun, but the tower cranes would be so booked up that we couldn’t keep them focused on the high-priority activities,” Enns says. “They’d just be stuck moving non-critical material around all day and night.”

On both towers, Sterling Crane was subcontracted to dismantle PCL’s tower cranes following the construction.

Scott Baraschuk, branch manager for Sterling Crane in Winnipeg says that the dismantling was a very straight forward operation, however it did require the use of a very large mobile crane.

“Whatever they need, we’ll handle for them,” Baraschuk says. “In this scenario, it was the dismantling – to provide a mobile crane to dismantle their tower crane; just to provide a means of hoisting everything down. This particular one was the Liebherr LTM 1500 8.1. When we erected these towers a few years ago, the intent was to down climb the tower back to roughly 150 feet for dismantling. We now have the LTM 1500 available so I suggested we look at taking the tower at full height. This reduced the dismantle time by several days and eliminated the need to climb the tower crane down.”

The Liebherr LTM 1500 8.1 was utilized for the dismantling operations on both towers, however, it was used in two different configurations for each tower. During the dismantling for Tower 2, the crane was configured in a way that made it one of the tallest cranes ever seen in the Winnipeg skyline. Media coverage of the project claimed it was the single tallest crane ever used in the city, but Baraschuk can’t confirm that.

“I can’t say for certain, but it is certainly a contender,” he says. “It had roughly 380 feet of tip height in this configuration.”

It was an easy choice to use the Liebherr LTM 1500 for Tower 1, since it was locally available and easily capable of performing the job. Tower 2 had the same demands, but the flexibility of the 276-ft. telescopic boom was an added benefit given the site restrictions and their setup.

“We were able to maintain our setup into one city block, avoiding the closure of an intersection to build a long luffing jib. This resulted in significant time and cost savings to the customer.” Baraschuk says. “The biggest challenge is site congestion with a crane this large. When working in a downtown setting, you have got a lot of obstacles – you have public safety to be concerned about and numerous underground utilities as well.”

“We pride ourselves on having a fleet with industry leading technology and we have purchased a number of these units to capture new markets and niche jobs where you need a certain type and size of crane to perform,” adds Jeff Chernish, director of business development for Sterling Crane. “We provide efficient customer solutions similar in nature throughout Canada and we appreciate the visibility that this has brought us in Winnipeg.”

Tower 1 at 242 Hargrave Street is quickly approaching substantial completion, scheduled for the end of June 2018. It is comprised of retail and office space, and construction crews are currently focused on lobby finishes, amenity floor finishes, and mechanical, electrical, and elevator commissioning.

Tower 2 at 225 Carlton Street is scheduled to be completed a year from now. It contains some retail and office space but is predominantly comprised of residential rental suites. Construction teams are currently installing a high-performance glass curtain wall, after which internal finishes in the lobby and suites will become the focus, with an aim to welcome residents next spring.

Phase 2 of the project is a hotel and condominium complex being developed by Sutton Place Hotel & Residences. They aim to break ground this summer and be complete in 2020 or 2021.
