Get to Know Your Training Specialist – Kevin Giles CRSP

Training -Kevin-Giles

Kevin Giles, CRSP is one of our highly experienced Training Specialists and Safety Consultants. We sat down with him to find out more about him and how he decided to choose training as a career path.

Tell us about your educational background?

Kevin: I’ve always had a passion for the outdoors, so I started my education at the Nova Scotia Community College in the Forestry Program. I went on to further my education at the Maritime Forest Ranger School in Fredericton NB and graduated in in 1997.

During the next 11 years I worked in many different aspects of forestry from privet woodlot management, and saw milling to large scale harvesting operations. In every job I did I always played a strong role in health and safety of the workplace, it became clear to me that this was the area I wanted to concentrate on, and I never turned back.

Training Kevin Giles 2

 

I completed the Health and Safety Professional (HSP) designation and was one of the first people to achieve the designation from the Canadian Association Of Provincial Safety Councils. In 2011 a major highlight of my career was achieving the Canadian Registered Safety Professional (CRSP) designation with the Canadian Board of Registered Safety Professionals.

During my 11 years with Hercules I have furthered my education in many areas including; train the trainer programs, Master Rigger, non-destructive testing, and completing 4 diploma programs with the Lifting Equipment Engineers Association (LEEA). As you can tell I love to grow my knowledge and am highly committed to continuous education, my next goal is to complete the Diploma program in Occupational Health and Safety with the University of New Brunswick, only 3 more courses to go!

What made you decide to go into this industry?

Kevin: As I mentioned the safety industry sort of came to me rather than me seeking it out. With every job I ever had since I was 16 years old I played some kind of role in safety, from being a first aid provider on the ski hills with the Canadian Ski Patrol, to being part of various safety committees, and developing policies and procedures with large industrial forestry operations and sawmills. The rigging industry has given me the opportunity to explore so many aspects of safety I find It amazing to think of.

Can you tell us about your work experience before joining Hercules SLR?

Kevin: Upon graduation from the Maritime Forest Ranger School I worked with the SNB Wood Co-op and the Hants County Woodlot Owners Association helping private woodlot owners manage their woodlots for a verity of forest productivity, environmental, and wildlife goals. This was a very rewarding time and experience in my forestry career.

After 4 years in the privet woodlot industry I moved into several new roles in a more industrial forestry operation with JD Irving ltd., working as harvesting supervisor, planer mill supervisor, and chip plant supervisor. This industrial atmosphere gave me to opportunity to work with contractors, unionized workers, students and many more. Working in these environments which already had a very strong safety culture helped me to build confidence and a broad knowledge base of various safety program elements.

What made you want to transition into training?

Kevin: I’ve always enjoyed helping people and sharing my knowledge whenever I could. I started formally instructing with the Canadian Red Cross first aid programs and have taught for the Canadian Ski Patrol, Saint John Ambulance, Safety Services Nova Scotia, and various employers along the way. I enjoy when I can help a student or coworker have that “lightbulb moment” when everything seems to come together and they get a clear understanding of the topic.

Why did you decide to work for Hercules SLR?

Kevin: When I decided that I wanted to pursue a career in safety the opportunity to Join the Hercules team came available. The timing was right and it was the perfect fit. Having a fulltime safety professional was new for the company and it was new for me. I am very happy to say the company and myself have grown together over the last 11 years to build a strong safety culture.

Where have you traveled during your time as a training specialist for Hercules SLR?

Kevin: The majority of the training that we deliver is based in the maritime provinces, but we are able to deliver training anywhere in Canada.  I’ve delivered training from the coast of NL to the coast of BC and many stops in between, including Ontario, Quebec, PEI, NB and Alberta.

Where have you enjoyed traveling to most for training?

Training Kevin-Giles-3

Kevin: Traveling to different parts of NL over the past few years has been interesting. The people are great, and it has been very interesting to see the change in safety culture since the oil industry has grown so much there. Some of the most memorable places to provide training has been in a federal prison, on various ships, sawmills, and airplane hangars. Sometimes you just don’t know what you are getting into and that is always exciting.

Is there anywhere that you would like to travel to in the future with Hercules SLR?

Kevin: I would really like to travel to the northern parts of Canada maybe up to Yellowknife or somewhere in the North West Territories.

Lastly, is there anything that you hope to accomplish during your career in the industry?

Kevin: I hope to be able to make a great success of our Hercules Training Academy and some day expand the course offerings to include some more of the academic safety programs to help companies build a strong safety culture.

Crane Hand Signals – Downloadable Reference Sheet

Crane-hand-signals

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.

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. Construction sites can be exceptionally loud and busy, meaning verbal communication is at risk of being drowned out by roaring machinery.

So how does an operator, with a load suspended in air, follow instructions from their team? Using the simple but effective method of 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!

A Simple Solution
Hand signals provide a simple solution for the communication issues faced by crane operators. Although radios can be used to relay messages across the site, there are some situations when an operator will need extra assistance.

Crane Hand Signals 2

Construction sites are loud. They produce a high level of noise from activities such as digging, piling, and drilling, therefore it can be difficult to convey instruction in an accurate and time efficient way. There are also times when an operator’s directional visibility is obstructed or the visibility of a load area is partially blocked, conducting a lift within these types of conditions can put the operator and the workers around them at serious risk of injury.

Although it recommended to use hand signals during all lifts, it is in these situations when a signal person will definitely be called upon. Easy to understand, hand signals help the operator avoid any potential hazards, completing actions in a safe and timely manner.

The Role of a Signal Person
As the eyes and the ears of a dedicated area or crane, a signal person 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 signal person 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 signal person 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.

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.

Safety First
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.

Working Load Limit Vs. Breaking Strength

Working Load

When it comes to rigging like ratchet straps, winch straps, and just about any other type of strap in the industry, working load limit (WLL) and breaking strength are commonly used measuring metrics.

Every piece of load-bearing wire or rigging equipment carries its own working load limit and break strength rating. These numbers let the user know how much weight that piece of rigging is capable of securing. Though they are usually clearly stated, there is often some confusion about what the two terms mean.

Working Load Limit

WLL refers to the maximum allowed weight that a piece of rigging can handle under normal conditions. For instance, a winch strap with a WLL of 6,000 pounds should not be used to secure any load above that weight, as it exceeds what it is rated for. WLL is 1/3 of the breaking strength rating, therefore a strap with a WLL of 6,000 pounds would have a breaking strength of 18,000 pounds.

Break Strength

Break strength refers to the point at which any section of a given cargo strap or piece of rigging will f

ratchet-strap

ail. Break strength is determined by the weakest point of the rigging in question, whether it be the webbing, end fittings, or tensioning device.

For example, if a ratchet strap is made with end fittings, webbing, and a ratchet that are all rated for 10,000 pounds breaking strength, the overall strength of the product is 10,000 pounds. If any component of the ratchet strap has a lower breaking strength though, the break strength of the unit drops to the rating of the weakest component.

It is critical to understand the differences between the two figures and to make sure that any time you are securing a load, you do so with capable rigging. A failure could not only be costly, but dangerous as well.

Turnbuckles – Creating Tension in Multiple Industries

Turnbuckles, stretching screws or bottlescrews are a device for adjusting the tension or length of ropes, cables, tie rods, and other tensioning systems. It normally consists of two threaded eye bolts, one screwed into each end of a small metal frame, one with a left-hand thread and the other with a right-hand thread. The tension can be adjusted by rotating the frame, which causes both eye bolts to be screwed in or out simultaneously, without twisting the eye bolts or attached cables.

Turnbuckles are most commonly used in applications which require a great deal of tension; they can range inturnbuckles mass from about ten grams for thin cable used in a garden fence, to thousands of kilograms for structural elements in buildings and suspension bridges.

Construction

Turnbuckles with various size are popularly used in construction. They combine strength and durability, yet are simple to set up and adjust. Very small turnbuckles (as light as 10 grams) might be used to support a fence in a garden. On the other hand, extremely large turnbuckles (as heavy as several thousand kilograms) are widely used as support high-rise buildings or in structures such as bridges.

Aircraft

Turnbuckles have been used in aircraft construction. Historically, biplanes might use turnbuckles to adjust the tension on structural wires bracing their wings. Turnbuckles are also widely used on flexible cables in flight control systems. In both cases they are secured with lockwire or specifically designed wire clips to prevent them from turning and losing tension due to vibration.

Shipping

Turnbuckles are used for tensioning a ship’s rigging and lashings. This device is also known as a bottlescrew in this context.

Sports

Turnbuckles find common use to tension the ropes in professional wrestling rings and boxing rings, where they serve as the attachment between the ring ropes and ring posts. Rather than the usual bare metal, here the turnbuckles are covered with padding in order to protect participants and staff. Turnbuckles even play a part in professional wrestling where they are often dramatically used by participants as part of their offensive move set.

Entertainment industry

Turnbuckles are used in nearly all rigging performed in the entertainment industry, including theatre, film, and live concert performances. In entertainment rigging, turnbuckles are more commonly used to make small adjustments in line lengths. This is generally to make a flown unit sit parallel to the stage. Another way a turnbuckle could prove helpful is with making very minor height or angle adjustments.

Pipe systems

Turnbuckles are used in piping systems as a way to provide minor adjustments for field inconsistencies. This also allows for a minimum amount of resistance when transferring the load to the support components.

Orthopaedics

A type of splint is used for upper limb to produce gradual stretching over contracted joint by its turn buckle mechanism. Used to treat stiff elbow and Volkmann Ischemic Contracture.

Stunt Rigging: Behind the Camera with an Industry Star

Stunt-Rigging

Stunt Rigging in the Movie Industry.

Article by By Mike Chalmers for Wire Rope Exchange

Many of the world’s most famous faces and personalities will garner precious amounts of camera time at the Academy Awards at the Dolby Theatre in Hollywood, California. And the films themselves will, at least for a night, finally receive their just deserves.

What probably won’t receive as much of the spotlight is the enormous amount of stunt rigging that goes into a Hollywood production. In fact, entertainment rigging is a world within a world, with its own celebrities, mad scientists, daredevils, and rock stars.

Oddly enough, Wire Rope Exchange had the great fortune to track down one of the biggest names in the world of entertainment rigging (and in this case, stunt rigging), and ask him about the ins and outs of this “world,” and what it’s like to set up and operate rigging projects that comprise some of the most talked-about films of the year — films that end up on stage in envelopes at the Dolby Theatre each February.

Keir Beck is one of the most experienced and sought after Stunt Rigger/Stunt Coordinators on Earth. With over two decades of adventure sports and climbing under his belt, and nearly fifteen years at the helm of his own

Stunt Rigging
Teamwork and comradery is the glue that keeps entertainment rigging teams safe, successful, and always at the top of their game.

entertainment rigging endeavor, Beck has become a world-renowned specialist in the Stunt Rigging and Coordinating arena. His resume is a head-turner: Matrix Reloaded, Matrix Revolutions, Casino Royale, Superman Returns, San Andreas, Narnia, Pitch Black, Sherlock Holmes, Mad Max 4: Fury Road, X-Men Origins: Wolverine, and many more.

In 2001, Beck started his own specialized rigging company — Inmotion Rigging — based in Arundel Old, Australia, with an additional location in Inglewood, California. Inmotion caters to the film and entertainment industry, working all around the world to provide creative and unique rigging solutions for both stunt and camera departments, game shows, live circus, and aerial entertainment.

We got hold of Beck while he jumped through time zones between California and Australia. Instantly likable, here’s what he had to say.

Wire Rope Exchange: You’re one of the most notable names in the industry. Can you give us a quick run-down of your job description day-to-day, and how you landed within this line of work?

Beck: My title is either Stunt Rigging Coordinator or just Stunt Coordinator. Working on a film that is heavily weighted with rigging-related stunts means that on a day-to-day basis, I would be either designing rigs from the storyboards or pre-visualization, doing safety reports, overseeing rigs going up, rehearsing, or filming. With more complex rigs, there’s a lot of time just thinking about how you can achieve what the director is asking.

Wire Rope Slings – Care and Maintenance

Wire-Rope-Sling

Terry Young, president of Construction Safety Experts, in the US, discusses identification, inspection and removal criteria for wire rope slings. The ASMEB30.9-2006 Standard requires wire rope slings to show the name or trademark of the manufacturer, diameter or size, number of legs, if more than one, and the rated loads for the types of hitches used and the angle upon which it is based.

The initial identification is done by the manufacturer and should be maintained by the user so as to be legible during the life of the sling. Replacement of wire rope slings identification should be considered as a repair and is required to be performed by the manufacturer or a qualified person. It must be marked to identify the repairing agency.

Wire rope sling 2

Additional proof testing is not required when replacing sling identification. An initial inspection should be performed prior to using new, altered, modified or repaired wire rope slings. It should be conducted by a designated person to verify compliance with applicable ASME 30.9-2006 standards.

A frequent visual inspection for damage must be performed by the user or designated person each day or shift the sling is used. The best safety practice is to inspect the wire rope before each use, task or lift.

Any condition meeting the ASME 30.9 – 2006 removal criteria or other condition that may result in a hazard must result in the sling being removed from service. The sling should then not be returned to service until approved by a qualified person. Written records are not required for frequent inspections.

A periodic inspection is to be conducted at intervals, not exceeding one year. This requires a complete inspection for damage to the sling by a designated person. The inspection should be conducted on the entire length, including splices, end attachments and fittings.

The frequency of periodic inspections should be based on frequency of use, severity of service conditions, nature of lifts being made and experience gained from the service life of slings used in similar circumstances or conditions.

Guidelines for the time intervals are

  • Normal service – yearly
  • Severe service – monthly to quarterly
  • Special service – as recommended by a qualified person or manufacturer
  • A written record shall be made and maintained of the most recent periodic inspection

Removal criteria

A wire rope sling shall be removed from service if conditions such as the following are present.

  • Missing or illegible sling identification
  • Broken wires
  • For strand- laid and single-part slings, 10 randomly broken wires in one rope lay, or five broken wires in one strand in one lay.
  • For cable-laid slings, 20 broken wires per lay.
  • For six- part braided slings 20 broken wires per braid.
  • For eight-part braided slings 40 broken wires per braid.
  • Severe localized abrasion or scraping
  • Kinking, crushing, birdcaging or any other damage resulting in damage to the rope structure
  • Evidence of heat damage
  • End attachments that are cracked, deformed or worn to the extent that the strength of the sling is substantially affected
  • Severe corrosion of the rope, end attachments or fittings.
  • Other conditions including visible damage that may cause doubt to the continued use of the sling

Hook removal criteria is listed in the ASME B30.10 Standard. Rigging hardware removal criteria is listed in the ASME B30.26 Standard.

Hercules to the Rescue At Voisey Nickel Mine

Voisey-Nickel-Mine

Mid-September, Noah Hawes and Barry Young from the Inspections Department of Hercules SLR Dartmouth, ventured to the isolated Nickel Mine of Voisey Bay in Labrador Newfoundland where in 1993, a large nickel deposit was discovered in the hills along the western shore of Potato Island by Archean Inc. a prospecting firm hired by Diamond Fields Resources Inc.

This nickel deposit is considered to be one of the most substantial mineral discoveries in Canada in the last 40 years and is estimated to contain 141 million tonnes at 1.6% nickel. Surface mining began in Voisey Bay in 2005 to access the nickel deposit. Currently, the mining rights for the Voisey Bay nickel deposit belong to the Toronto-headquartered Vale Inco company, a subsidiary of Vale. The bulk carrier ship Umiak I was built to transport ore from the mine.

On June 11, 2018, Vale announced it is moving forward with its underground mine at Voisey Bay. The move will extend the mine’s operating life by at least 15 years. Over the five-year construction, more than 16,000 person-years of employment will be created, and the first ore is expected no later than April 2021.

Noah and Barry’s task at the Voisey mine was to replace the end post for 3M’s recent roof lifelines recall. There was an element of apprehension as this was the first time they had undertaken a job of this type that was so remote and far away.

“We didn’t know what the job would entail, how complex the job would be, and what weather conditions we may be faced with”.

However, any concerns they had were completely unfounded as they accomplished the job without any issues or complications. They did such a great job in fact, that Vale are now talking about Hercules annually re-certifying all their lifelines.

LEEA Logo

The Hercules Inspections department are the best in the business and widely regarded as industry experts in their field. We ensure that all our inspectors are trained to an exceptionally high standard. Currently we are expanding our inspector training nationally to include LEEA (The Lifting Equipment Engineers Association) certification.

We believe in going that extra mile. We will travel great distances to help our customers and get the job done. We cultivate customer relationships through innovation, expertise and innovation.

Crane & Rigging Companies join Forces for Lifting Project

crane-seattle

Omega Morgan crane superintendent Eldon Ash and senior engineer Kai Farrar, as well as Apex Steel owner Kevin Koester and engineer Ron Roberts, were tasked with an intriguing and complicated lifting challenge. More than a year of planning, engineering, testing and simulations went into the design of the project known as 2+U, named for its location on 2nd Avenue and University Street in Seattle, WA. The high-rise project is being developed by Skanska USA.

The engineering of structural columns supporting the proposed 38-story office complex provided an intricate challenge in ensuring the Y-shaped columns could distribute the weight of every floor above evenly on the foundation while maintaining a 72-degree angle of installation.

Faced with several issues that could have stalled the project before it even began, Omega Morgan and Apex Steel engineers went over several options to determine the best way to perform the required lifts when available space and increased weights of the columns caused the original lift plan to be scrapped.

“Initially, we were going to use two cranes, and then we were going to use a crane and a tri-lifter, but as the load got heavier and heavier, and as the jobsite got tighter and tighter for access, we had to come up with some more innovative ways to pick and stand these things up, and that’s when I came up with this idea,” said Farrar.

Rigging gear

  • 37.5-ton JDN 37TI
  • Air Chain Hoist with 35-foot HOLCrane Seattle 2
  • 50-ton JDN 50TS
  • Air Chain Hoist with 35-foot HOL
  • 60-ton WLL
  • Single Sheave Blocks, 24-inch diameter and 2-inch wire rope

Skip-around schedule

Charged with leveraging their skill and experience to come up with a way to utilize a limited amount space and a strict schedule of road closures to set the foundation for the office tower project, Omega Morgan and Apex had to adapt a skip-around schedule based on which roads would be closed to complete the project while avoiding falling behind schedule.

The engineering of the supports that would be installed at a 72-degree angle – and which start on the second floor and run up through the next five stories – left no room for error in the construction and placement. Further, engineering the lifts of each section of the columns posed its own problem. With the columns being assembled in a sort of “Y” shape, the assembled height and weight made it essential to install them in sections. Fully assembled, each column came in with the base, installed separately, weighing in around 50,000 pounds with two arms run at a 72-degree angle that span around 60 to 70 feet tall with a final weight of 165,400 pounds for the heaviest columns. The rigging itself weighed 5,528 pounds. Ensuring all pieces lined up properly to evenly distribute the weight with only enough space for one crane, calculations had to be precise.

Once on-site, further challenges crept up that called for on-the-fly adjustments. The position of the crane had to be modified to avoid swinging the counterweight too close to a tree trunk, which would break branches. The crane was moved five feet away to be able to tie the branches back and assure no contact. This move required the crane be set on a wooden ramp to level it out given the slope of University Avenue.

Once the columns were fabricated and weighed, the numbers came in significantly heavier than planned. The tight nature of the jobsite inside the building did not allow space for two cranes with the capacity required. It became clear that a rigging scenario in which a single crane could pick and upright the columns would be necessary.

Because of the tight space on-site, it was not possible to use a boom suspension system to stabilize a longer boom to get enough capacity to make the picks, limiting the boom length to 118 feet with no boom suspension. The short boom and head room required that the single crane rigging setup be as short as possible.

The two cranes on the job were a 485-ton capacity Liebherr LTM 1400 all-terrain crane rigged with a main boom of 118 feet and a maximum radius of 45 feet and a 550-ton Grove GMK 7550 rigged with a main boom of 148 feet and a maximum radius of 70 feet.

Equipping the cranes with a 37.5-ton air chain hoist and a pair of 60-ton sheave blocks, the crew was able to perform the work typically done with the aid of a tailing device while utilizing only one crane and saving on the head room required to perform the lift.

“One thing that was unique about this rigging scenario was that using the rolling blocks and the chain lift in this way, as the load goes through its rotation, the head height at the final rotation is minimized compared to other systems that are similar like a tri-block that runs the secondary line down, but the rigging height that you end up with was too much for our project,” said Farrar. “This rolling block/hoist system really minimizes the head room once the columns are upright. Because the site was so tight, we couldn’t use any kind of boom suspension like a mega-wing or guy wires since they stuck out too far and would have interfered with the building core and a lot of the structural elements, so we had to stick to short-length, main boom only and couldn’t have any tall rigging.”

Farrar engineered the rolling block setup to create the safest, most efficient pick possible that allowed them to run the lift with one crane and save on the space required compared with other options. Limited on viable options, the use of a tri-block system would no longer work in this application, so the creative use of an air chain hoist paired with rolling blocks saved time and money. Keeping a spare 50-ton air chain hoist on site, which never left its shipping container, ensured there would be minimal risk of unplanned downtime in the event of a mechanical breakdown.
