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.

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.

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.

Creative rigging

Crane-Seattle-3

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.

New Safety Legislation for Alberta’s Agriculture Sector

Safety System

A new legislation will soon require Alberta farmers to ensure their farms are equipped with proper safety plans. Emergency response, fall protection, and hazard assessments are just some of the plans that will be implemented to ensure worker safety on Alberta farms. The Alberta agriculture sector will now begin using checklists to help maintain these safety programs.

Alberta farms and ranches with paid employees will soon be required to follow a slate of new safety rules, some of which address using seatbelts, operating older equipment and conducting inspections.

The province announced the incoming changes in an effort to strike a balance between keeping farm workers safe while ensuring operators can practically abide by

Agriculture

them. They don’t apply to family members or neighbours helping on the farm.

Starting Dec. 1, seatbelts will be required wherever possible for all equipment that is over 700 kilograms. If it’s not possible to install them, the rules state farmers must use reasonably practical methods, like driving slow.

As well, farmers will still be able to use or sell existing equipment even if it’s not up to the latest manufacturer code. This means farmers won’t need engineers to come onto their farm to write up safety manuals for old equipment.

As well, these legacy equipment rules won’t affect dealers because all new equipment is considered up to code.

The rules regarding seatbelts and old equipment were some of the main sticking points among producers last fall, which is when the technical farm working groups put forward recommendations for review.

“It didn’t make sense for us to bend on legacy equipment,” said Agriculture Minister Oneil Carlier.

In fact, the contentious rules were years in the making. Following massive protests in 2015, the government did extensive consultations with groups like the AgCoalition, which was established to provide advice on farm safety, to come up with changes that it hoped would ease concerns.

As well, AgSafe Alberta, a producer-led group, was developed to help farms get up to date on the incoming changes.

Other rules state that farmers will be able to raise or lower workers in loader buckets in the rare case that it’s not reasonable or practical to use a machine for that purpose.

As well, producers using equipment weighing over 700 kg will need to complete a rollover hazard assessment and either use a rollover protective structure or do other safe working procedures.

The rules said fall-protection equipment might not be practical or possible, so safe work procedures can be grain-elevatorimplemented in place of this.

Workers can also be transported on loads under controlled conditions. Their access to work areas must be safe, and structures must be strong enough to support them.

The province is providing $6 million over the course of three years for the purpose of helping producers with waged employees adopt the new rules. It will provide up to $10,000 per person. More details on the program will be announced later in the year.In terms of hazard inspections, farmers can conduct inspections whenever they feel necessary. Visual inspections before using equipment are good enough.

Farms that have 20 or more workers who are employed for 90 days or longer must establish a health and safety committee. The committee must keep records of safety meetings and make recommendations to the employer on how they can improve safety.

Farms with fewer than 20 workers who are employed for 90 days or longer will be required to have someone designated as a health and safety representative. The representative will be responsible for addressing complaints and doing regular inspections to mitigate potential hazards.

OHS officers can be called to investigate a farm if a complaint is filed or if the farm reported a serious injury or death.

In the long run, OHS visits will be focused on farms with higher incidences of injuries and incidents. They will focus on compliance assistance and promote AgSafe Alberta resources.

Construction Industry Draws $1.3 Billion in Venture Capital

Ventire-Captital-in-Construction

In a bid to digitize building trades, investors have already bet big on the transformative power of new startups

Move over meal deliveries and mobility startups: The construction industry has become a new focal point for venture capital funds and tech investment.

Investment in AEC firms—architecture, engineering, and construction—have blossomed in the last few years, as a once low-tech, staid industry begins to feel the full impact of digital technology, especially when it comes to collaboration software, worksite monitoring, safety, and new design tools.

Tech Investment

Tech investment in construction has grown rapidly in the past decade—in 2008, global investment totaled $4.5 million across two deals—led by growing number of more active and specialized venture capital investors. According to data from CB Insights, the industry saw $882.3 million in investment last year across 103 deals, and has already bested that in 2018, racking up $1.38 billion across 61 deals.

While this year’s considerable investment is mostly due to a handful of sizable venture capital investments in companies such as Katerra, the Silicon Valley construction startup that received $865 million in a funding round that included the SoftBank Vision Fund, these mammoth deals only show the potential many see in these types of companies.

venture-capital-diggerFrom Low Tech to High Tech

“Construction is one of the least digitized industries, so many startups are seizing the opportunity to build technology that would increase efficiency within this market,” says Michael Wholey, an intelligence analyst for CB Insights. “As a result, funding and deal activity in the construction technology space has been increasing steadily over the past few years.”

Kaustubh Pandya, a principal at Brick & Mortar Ventures, a three-year-old San Francisco-based investment fund focused on AEC companies, says the technology to digitize buildings, including affordable sensors and better mobile technology, has the potential to make an industry known for long time frames and flexible deadlines more efficient.

According to a recent Crunchbase article, a number of startups are on the rise, including Rhumbix, which raised $20 million in venture capital investments for its mobile platform for the construction craft workforce, and Procore, which has built a cloud-based construction management software application and raised $229 million.

While there’s a desire to expand and diversify tech investment—”the world doesn’t need another general fund, there are plenty out there,” says Pandya—the size and scope of the construction and design field offers plenty of opportunities. A report from global consulting firm McKinsey found numerous areas for improvement and investment, especially in the realms of field productivity and site-performance management.

One of the main reasons investors see great potential is the relatively low growth in productivity in the building trades, relative to other industries. The McKinsey analysis found that construction labor productivity averaged 1 percent growth annually over the last two decades, compared to the 3 to 4 percent average found in other industries. If new technologies could help close that gap, that would add an estimated $1.6 trillion to the industry’s annual output.

The Frankensling – Custom Solutions for Rigging Dilemmas

Frankensling


The Town of Oakville Marina in Ontario had a reoccurring problem raising and lowering the masts and sails of the vessels as they handled the boats. Due the large volume of craft, the variations in size and space, they needed something that could do more than one mast or sail at a time. Enter Hercules SLR and ‘The Frankensling!

Frakensling Marina Crew
The Marina Crew

The solution they used to use was to manipulate each mast and sail individually, but this was time consuming, inefficient work. Moving multiple masts caused problems as the weight shifted as they were manipulated, became unstable and were in danger of damage. They needed something that was weight loaded to distribute an even application for the multiple height level adjusting of masts/sail raising and lowering.

The Marina came up with the solution of using slings looped together. This did not solve the whole problem, but made it more the process more efficient. There was still the strong possibility of damage as multiple slings were harder to control. The marina came to Hercules with the problem, looking for something that was efficient, robust and easy to use. Together we created what is now penned as the Frakensling.

Frakensling
The Frakensling at the Town of Oakville Marina

The sling gets attached to the mast or sail of the boat, which allows for a securing point every 12”. This Frankensling is 24ft, but it can be made to any size of specification as needed. At every 12” mark there is a loop to which a line or rigging part can be attached to ensure an even balanced load point at every stage of the moving procedure. The sling can be used at any height and the pattern modified for any type of craft or Marina.

The Frankensling
The Frakensling in Action

This is a great multi stage variable height sling. It’s a perfect for masts that have more than 1 spreader on them. The current sling for the Town of Oakville Marina is 2” wide and 24FT long. They are looking to refine the design by shifting from 2” wide to 1” wide.

The Frankensling
Securing loops every 12 in

It was pleasure to work with the Town of Oakville Marina, and Hercules SLR once again pulled out all the stops to custom make something that made the day to day work of our customers easier.

Doesn’t every Marina need a Frakensling?

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!”

Steel Wire Rope – How, Where, What and Why

steel wire rope

Steel wire rope is several strands of metal wire twisted into a helix forming a composite « rope », in a pattern known as « laid rope ». Larger diameter wire rope consists of multiple strands of such laid rope in a pattern known as « cable laid ».

In stricter senses the term « steel wire rope » refers to diameter larger than 3/8 inch (9.52 mm), with smaller gauges designated cable or cords. Initially wrought iron wires were used, but today steel is the main material used for wire ropes.

Historically, steel wire rope evolved from wrought iron chains, which had a record of mechanical failure. While Fraying_steel_wire_ropeflaws in chain links or solid steel bars can lead to catastrophic failure, flaws in the wires making up a steel cable are less critical as the other wires easily take up the load. While friction between the individual wires and strands causes wear over the life of the rope, it also helps to compensate for minor failures in the short run.

Steel wire ropes were developed starting with mining hoist applications in the 1830s. Wire ropes are used dynamically for lifting and hoisting in cranes and elevators, and for transmission of mechanical power. Wire rope is also used to transmit force in mechanisms, such as a Bowden cable or the control surfaces of an airplane connected to levers and pedals in the cockpit. Only aircraft cables have WSC (wire strand core). Also, aircraft cables are available in smaller diameters than steel wire rope. For example, aircraft cables are available in 3/64 in. diameter while most wire ropes begin at a 1/4 in. diameter. Static wire ropes are used to support structures such as suspension bridges or as guy wires to support towers. An aerial tramway relies on wire rope to support and move cargo overhead.

History

Modern steel wire rope was invented by the German mining engineer Wilhelm Albert in the years between 1831 and 1834 for use in mining in the Harz Mountains in Clausthal, Lower Saxony, Germany. It was quickly accepted because it proved superior to ropes made of hemp or to metal chains, such as had been used before.

Wilhelm Albert’s first ropes consisted of three strands consisting of four wires each. In 1840, Scotsman Robert Stirling Newall improved the process further. In America wire rope was manufactured by John A. Roebling, starting in 1841 and forming the basis for his success in suspension bridge building. Roebling introduced a number of innovations in the design, materials and manufacture of wire rope. Ever with an ear to technology developments in mining and railroading, Josiah White and Erskine Hazard, principal owners[9] of the Lehigh Coal & Navigation Company (LC&N Co.) — as they had with the first blast furnaces in the Lehigh Valley — built a Wire Rope factory in Mauch Chunk, Pennsylvania in 1848, which provided lift cables for the Ashley Planes project, then the back track planes of the Summit Hill & Mauch Chunk Railroad, improving its attractiveness as a premier tourism destination, and vastly improving the throughput of the coal capacity since return of cars dropped from nearly four hours to less than 20 minutes. The decades were witness to a burgeoning increase in deep shaft mining in both Europe and North America as surface mineral deposits were exhausted and miners had to chase layers along inclined layers. The era was early in railroad development and steam engines lacked sufficient tractive effort to climb steep slopes, so incline plane railways were common. This pushed development of cable hoists rapidly in the United States as surface deposits in the Anthracite Coal Region north and south dove deeper every year, and even the rich deposits in the Panther Creek Valley required LC&N Co. to drive their first shafts into lower slopes beginning Lansford and its Schuylkill County twin-town Coaldale.

The German engineering firm of Adolf Bleichert & Co. was founded in 1874 and began to build bicable aerial tramways for mining in the Ruhr Valley. With important patents, and dozens of working systems in Europe, Bleichert dominated the global industry, later licensing its designs and manufacturing techniques to Trenton Iron Works, New Jersey, USA which built systems across America. Adolf Bleichert & Co. went on to build hundreds of aerial tramways around the world: from Alaska to Argentina, Australia and Spitsbergen. The Bleichert company also built hundreds of aerial tramways for both the Imperial German Army and the Wehrmacht.

In the last half of the 19th century, steel wire rope systems were used as a means of transmitting mechanical power including for the new cable cars. Wire rope systems cost one-tenth as much and had lower friction losses than line shafts. Because of these advantages, wire rope systems were used to transmit power for a distance of a few miles or kilometers.

Safety

The steel wire ropes are stressed by fluctuating forces, by wear, by corrosion and in seldom cases by extreme forces. The rope life is finite and the safety is only ensured by inspection for the detection of wire breaks on a reference rope length, of cross-section loss, as well as other failures so that the wire rope can be replaced before a dangerous situation occurs. Installations should be designed to facilitate the inspection of the wire ropes.
