Product Spotlight: Hammerlock Coupling Links

What is a Hammerlock Coupling Link?

Hammerlock coupling links are used for attaching chain to master links, eye type hooks, installing a new branch to a sling or just connecting components during chain sling fabrication.

Hammerlock coupling links should NEVER be used to repair hoist chain—No coupling hardware should ever be used to repair a damaged link of chain. This can present a number of safety hazards to the operator and possibly the overall hoist. In the case of hoist chain damage or ware, the chain needs to be replaced as one piece.

Hammerlocks are also not appropriate for lengthening chain. Once again, if you desire a longer chain, you need to seek out a chain that is fabricated to the correct length, using the correct links.

Assembly and Disassembly of Hammerlock Coupling Links

Hammerlock coupling links are a favorite of riggers because they can so easily be assembled and disassembles in the field using only a hammer and punch.

How to assemble a hammerlock link:

  1. Bring the two halves of the body together so the center connectors are aligned
  2. Position the bushing in the center of the hammerlock, aligned with the connectors
  3. Insert the load pin through the hammerlock as far as you can by hand
  4. Hammer the load pin the rest of the way in, until all material is flush on both ends

 

Did you know the bushing in the center is one of the most important parts of a hammer coupling link? Without the bushing, the load pin on its own will not hold the hammerlock coupling together at all – It actually moves quite freely within the body on its own. The load pin is tapered on the ends which allows the bushing to sit in place and hold the hardware securely together. The bushing contains a spring-like system that allows the pin to push through when hammered, but returns to an un-movable state once in place – Unless directly hammered again using a punch!

How to disassemble a hammerlock link:

  1. Place the hammerlock link on a raised surface, creating room for the load pin to exit the bottom
  2. Align a punch with the center-top of the load pin
  3. Hammer the punch forcing the load pin out from the center of the hammerlock
  4. Pull now loosened parts apart by hand – It’s that easy!

A Look at the Towing Industry | Different Categories of Tow Trucks

A Look into the Towing Industry: Different Categories of Tow Trucks

Nothing puts a damper on your day quite like having your car break down as you’re trying to make your way through your day. When that does happen, you depend on towing companies to get your vehicle somewhere where it can be repaired safely. This is likely the extent of many people’s knowledge when it comes to tow trucks. They’re an industry that the everyday person wouldn’t think much of, until they are forced to Google the phone number of the nearest one, to save them from their rotten day.

Did you know there isn’t a one-size-fits-all tow truck? Towing companies often have a variety of vehicles on hand, each made for a different type of job. Tow jobs aren’t just limited to picking up small broken down cars on the side of the road, they also have to serve larger vehicles like RVs, box trucks and even the heaviest 18 wheelers. Even beyond the load size, tow companies have to be prepared to get vehicles out of hard-to-maneuver situations in the unfortunate case of an accident.

Tow trucks can be sorted into three basic types, light-duty, medium-duty and heavy-duty.

Light-Duty Tow Trucks

Light-duty tow trucks are used for the majority of incidents and are sent out to tow cars, motorcycles and smaller trucks. They are capable of performing a variety of tasks such as removing abandoned vehicles, private property towing and accident recovery. They have the ability to maneuver through small lots or parking garages, but usually stick to jobs that are located on paved and flat terrain.

   

Light-duty tow trucks are Class A vehicles that are often either conventional or rollback wreckers. They are capable of towing between 7,000 and 11,000 pounds and often rely on winch & cable systems and wheel lifts to do their work.

Medium-Duty Tow Trucks

Medium-duty tow trucks are used for heavier duty jobs involving vehicles like box trucks, RV’s and farm equipment. They are also the choice for certain recovery operations for smaller vehicles because they have a larger range of configurations such as: lowering platforms or landolls, automatic trailers, low-profile trailers, and boom lifts. However, since they are a bigger vehicle, they are not ideal for tighter environments like parking lots.

 

 

 

 

 

 

Medium-duty tow trucks are Class B vehicles that often feature some varying styles of flatbed. They are capable of towing between 7,000 and 17,000 pounds and feature at least a 12-ton capacity boom lift, 5-ton winch, and 5-ton wheel lift.

Heavy-Duty Tow Trucks

Heavy-duty tow trucks are the big guys. They are used for vehicles like garbage trucks, dump trucks and semi-trailers. These tow trucks handle the biggest loads and the most complicated recoveries. These are the tow trucks that vehicles like 18 wheelers depend on because not only are they capable of getting large vehicles themselves out of sticky situations, but also whatever that vehicle was hauling. They are also the tow truck used for vehicles that have gone off the road or down an embankment.

These are Class A vehicles that are required to feature at least a 25-ton boom lift, 25-ton winch and 6-ton wheel lift. They are capable of towing any load greater than 17,000 pounds!


The jobs that these tow trucks perform rely on more than just the truck itself. As we’ve mentioned above, each truck uses a different type of lifting and towing equipment. Especially when dealing with heavy-duty tow jobs, it’s extremely important that the tow truck is outfitted with high-quality lifting gear that won’t break under the pressure.

That’s where YOKE comes in! Since 1985, YOKE has been manufacturing durable, reliable & high-quality hardware that keeps your load secure, and your team safe. No need to choose between quality and affordability, YOKE provides top safety certified lifting equipment without the big price tag.

ISO AND ROAD VEHICLES iso and road vehicles statistics

DID YOU KNOW? Anyone who has driven a road vehicle of almost any make, almost anywhere in the world, will have directly benefitted from ISO 2575, which specifies the familiar symbols for controls and indicators we are accustomed to seeing on the dashboard. 

Who benefits from ISO standards for road vehicles? 

We’ve discussed ISO and energy, construction, the supply chain and we’ve debunked some myths – But what about ISO and road vehicles? Read on to learn why ISO and your vehicle are so important. 

Consumers 

ISO standards make driving a vehicle simpler and safer, while protecting passengers (especially children) and pedestrians, and lower the cost of buying vehicles.

Regulators

ISO standards gives technical basis for regularly reviewed & improved legislation on things like safety and pollution. 

Manufacturers 

ISO Standards give specifications for safety, quality, performance and environmental impact. They set out harmonized requirements that enable outsourcing, fair competition, the participation of suppliers from developing countries and drive down costs as they facilitate competitive tendering. 

What do ISO Standards for road vehicles cover? 

iso and road vehicles

 

 

 

 

 

Much of the work in these areas is the focus of the ISO technical committee, called ISO/TC 22, Road Vehicles, which has developed more than 820 standards & updates worldwide. The committee’s made of 75 different participating and observing national standards bodies, as well as automotive-sector associations and international bodies such as the World Health Organization.

These standards aim to: 

  • Improve compatibility, interchangeability and safety
  • Specify the requirements for harmonized test procedures to evaluate performance.

Electric Vehicles 

ISO/TC 22 Road vehicles has also developed a range of standards specifically for electric, hybrid and fuel-cell road vehicles. A number of these provide requirements for functional safety, test methods, on-board energy storage systems and measuring fuel consumption.

ISO 17409 Electrically Propelled road vehicles connection to an external electric power supply—Safety requirements 

ISO 234741, Hybrid-electric road vehicles exhaust emissions and fuel consumption measurements—Part 1: Non-externally charged vehicles. 

Intelligent Transport Systems 

Increasingly, road vehicles are being equipped with systems and networks based on information and communication technologies intended to improve safety, traffic control, navigation, fee collection and identification. Today’s communication capabilities give vehicles the potential to anticipate and avoid collisions, transmit their position to emergency services in case of an accident, navigate the quickest route to their destination, take advantage of up-to-the-minute traffic reports, identify the nearest available parking space, minimize their carbon emissions and provide multimedia communications.

ISO/TC 204,Intelligent transport systems focuses mainly on this area and has developed more than 220 standards*. 

*These include the ISO 15638 series on telematics applications for regulated commercial freight vehicles (TARV) and ISO 11067, which gives performance requirements and test procedures for curve speed warning systems (CSWS).

Tyres and Other Components 

ISO/TX 3, Tyres, rims and valves has developed 78 standards, including the ISO 4000 series on passenger car tyres and rims and the ISO 4249 series on motorcycle tyres and rims. 

Road Safety

ISO 39001, Road traffic safety (RTS) management systems—Requirements with guidance for use, developed by ISO/TC 241, road traffic safety managementis widely regarded as a major contribution to the United Nations’ Decade of Action for Road Safety 2011-2020. 

Future ISO 39002, Good practices for implementing commuting safety management, aims to reduce the amount of fatalities and severity of injuries caused by road accidents, by providing solutions and recommending measures that organizations can use to protect their staff.

 Road-safety-related standards are also developed by other ISO technical committees, for example to make crossing the street safer for disabled persons. 

Vehicle Safety

With the latest technological progress bringing us everything from advanced navigation systems to driverless cars, putting measures in place to spot potential risks across the whole vehicle lifespan is more important than ever.

ISO 26262 (series), Road vehicles—Functional safety, outlines an automotive-specific risk-based approach to help avoid any potential system failures. 

Looking Forward

Cyber Security 

A quick look at your dashboard will give you an idea of how connected vehicles are – and it is only increasing. From your GPS to other gauges and sensors telling you when your tyre pressure is low, there is constant interaction between in-vehicle embedded systems that communicate wirelessly. As this interconnectivity grows, so does the risk of cyber-attacks, threatening not only our safety but our personal information. Work has recently started on standards to address these issues by providing recommendations and solutions for building cyber security into vehicles

Hydrogen Vehicle Stations

If fuel-cell, electric and alternative-fuel vehicles are the future, there need to be adequate stations for refuelling them.

A new technical specification, ISO/TX 19880-1, Gaseous hydrogen—Fuelling stations—Part:1 General requirements, will contribute to the proliferation of hydrogen fuelling stations by providing important guidelines on their safety and performance. It covers everything from hydrogen production and delivery, to compression, storage and fuelling of a hydrogen vehicle, and provides a useful stepping stone to an International Standard in this area, due to be published in 2017.

Heavy Lifting with Hercules SLR | How we Lift More than a Million

820-ton splitter vessel alberta

You might have heard about the Splitter vessel that recently travelled from Fort Saskatchewan from Edmonton and was the biggest load to ever travel on Alberta’s streets and provincial highways. 

The vessel, called a Splitter, will be installed at the Heartland Petrochemical Complex—It’s used to produce polypropylene plastic. The Splitter is seriously huge, weighing 820-tons, or 1,807,790lbs and is 96-metres long. This is as long as a CFL football field and as heavy as the Statue of Liberty. After assembly on-site, it weighed 1,200-tons, or 24,000,000lbs. Yep, 24-million pounds. 

The journey itself took 4-days—a trip that normally takes just 45-minutes by vehicle. The vessel travelled through what’s known as “Alberta’s High-Load Corridor” and used guide vehicles, safety personnel and trailers & tires that evenly distributed the load’s weight. The city of Edmonton worked with the province for over a year to plan the big move.

HERCULES SLR & THE SPLITTER VESSEL | WHAT WE DID

The end of the vessel’s journey is where Hercules SLR steps in.

Hercules SLR installed the drill lines for the Splitter vessel. Drill lines are wire rope that’s multi-threaded or reeved through typically in 6-12 parts. They travel between the block and crown so drill strings can lower and lift in-and-out of a wellbore. 

Before the lift, Hercules SLR re-certified all their wire rope slings. Since this lift was so enormous, the risk was amplified. It is considered a critical lift—This means taking proper risk assessment measures is ultra-important to plan and ensure risk is minimized. ASME standards suggest you inspect your lifting equipment and hardware at least once a year.

Hercules SLR performed a rigorous inspection and calculated the lift to all risk factors. Since the rigging holds and secures the load to the crane, this is an extremely important step that Hercules SLR’s rigger’s take to ensure the load will be moved without damaging the equipment, running into obstacles or injure surrounding people. 

Check out photos of this enormous vessel and rigging below.
