HOOKLIFTS VS CABLE HOISTS

WHILE CABLE HOISTS ARE MORE ESTABLISHED IN WASTE AND RECYCLING, HOOKLIFTS CAN PROVIDE IMPROVED VERSATILITY, EFFICIENCY AND SAFETY

According to Tim Worman, product manager for demountables at Stellar Industries, when it comes to loading containers or truck bodies onto a truck chassis, the North American waste and recycling market has traditionally favoured the cable hoist, while the hooklift has been more prominent internationally, where urban space is generally tighter. Canada has been somewhere in between, based on influence from both markets.

He describes the two categories of demountables in basic terms. “Cable hoists use a cable that is manually connected to a container for loading and unloading onto a truck, using a hydraulically operated reeving system, and range up to 75,000-pound-capacity.

“Hooklift hoists use a hook assembly to connect to containers, from the cab of the chassis, to load and unload on the truck, and range up to about 65,000 pounds capacity. Both can provide loading and off-loading of waste and recyclable containers at any site, when matched with a properly configured truck chassis.”

Worman says Stellar Industries was founded in 1990 specifically to build hooklifts in North America, and since then they’ve been designing and building hooklifts in a multitude of configurations. “We acquired K-PAC in March of 2008,” he continues. “That acquisition got us into the cable hoist market, which we’ve been producing since that time. Worman goes on to say that of the two products they consider hooklifts to be the more efficient system.

He adds that for recycling and waste, the best option ultimately depends on the BY KEITH BARKER, EDITOR

application and systems already in place.

“The biggest reason that certain markets, including recycling and waste, use a lot of cable hoists still today is that their fleet of containers are set up for cable hoists, not hooklifts, and the cost to convert them means it usually doesn’t make business sense to do so.

“As we have looked at the variables between the two markets, the hooklift makes the most sense if you’re new to the business or doing a large-scale equipment swap.”

When considering unit capacity Worman says the two types of demountable have similar capacities, up to 65,000 pounds, with cable hoist units going as high as 75,000 pounds.

He says that for the most part, in North America for refuse and recycling, mixed waste, scrap and C&D hauling, cable hoists are still most commonly used. “The refuse and recycling market are really where cable hoists live,” he continues. “If you look at refuse, especially with larger setups, the cable hoist is the equipment that everybody uses because their containers are set up for it. Cable hoists fit well for big refuse collection companies. When you look at the recycling market, primarily scrap, they also use cable hoists. It’s a very mature market and that’s what they started with.

“But if I were a new start-up, hauling refuse or recyclables, I’d go right to a hooklift, due to their improved versatility, efficiency and safety gains.”

HOOKLIFT BENEFITS: VERSATILITY, EFFICIENCY AND SAFER OPERATION

According to Worman, one of the key benefits of the hooklift is that it not only efficiently handles containers, but there is a magnitude of different bodies that can easily be swapped in and out.

“There’s a litany of things you can do with that single asset for the job you need to do that day,” he says. “You don’t have to have five trucks sitting around, when one truck can easily be configured for different tasks using various interchangeable bodies. You can have one truck with five beds, and you just adapt to what you’re going to do the next day.”

Another factor to think about when comparing hooklifts vs cable hoists is efficiency when collecting containers.

With a cable hoist, users are more limited in the number of picks they can do per day because of the process behind it. Worman says the operator has to get out of the truck, pull the cable out, hook the cable to the container, return to the truck, and proceed to pull the container up. When he drops the container, this process is also followed, in reverse. This process has to happen with each pick up and drop of a container when using a cable hoist, but not with a hooklift.

When working with a hooklift, an operator eliminates extra steps to hook to a container. The user can deploy the hook, back up to the container, hook the container, and pull it onto the truck without ever leaving the truck cab. The efficiency gain comes from not having to continuously enter and exit the cab.

“We’ve looked at this closely, and in our estimation, if you were to switch to a hooklift, you could go from 10 picks per day to roughly 12 picks per day,” he says. “In this scenario that would be a 12 percent gain in efficiency. By doing that with a single asset, you’re putting more money into the profitability of your organization.”

A third important benefit of hooklifts compared to cable hoists is safety. Worman first emphasizes that users of any demountable should always check the jobsite before deploying anything. Whatever system is being used, haulers need to make sure there’s nobody around containers, around the truck or overhead.

With a hooklift, Worman says safer operation comes simply because the operator is not out of the cab as much, or between the container and the truck at any time to hook to, or disconnect from, a container.

“When the operator is dropping or picking up a container, they never have to leave the cab,” Worman emphasizes. “They can do it all from the comfort of their seat, which can’t be said for a cable hoist.

“Another safer operation factor for a hooklift over cable hoist, is the mitigation of operators walking in unfavourable conditions, like mud, where they don’t have to drag the large, heavy cable through the environment to hook to the container,” he says.

“With the cable hoist process, you could see an increase in injuries, such as back, hand or muscle pulls.

“These injuries are largely eliminated by having operators do the work from the truck cab – which they can only do with a hooklift.” RPN

Heil’s latest automated side loader designed for easier operation and maintenance

Heil recently launched the Command-SST Automated Side Loader (ASL), which incorporates a host of new technologies designed to enhance safety, operational comfort, productivity and maintenance simplicity.

According to Pat Carroll, president of Environmental Solutions Group (Heil’s parent company) “The Command-SST is the culmination of almost a decade of design and innovation, based on customer feedback regarding unfulfilled needs. Our engineers used this data to create a product that truly delivers on customer performance expectations.”

He said one of the primary objectives that Heil engineers addressed was the development of an automated side loader that would thrive amid operator and maintenance technician turnover, a problem identified early on in customer interviews.

“We knew we had to deliver a side loader that was easier to operate for new drivers and simple

can be easily swapped out if the arm is damaged,” said Carroll. "This means that fleets running Command-SST’s will have better operational metrics and a far better return on investment. That’s all part of delivering the lowest total cost of collection.”

The Command-SST is mounted to a Heil Durapack body, weighing 2,000 pounds less than other side loaders,

to maintain with fewer moving parts,” added Carroll. “The Command-SST has far fewer moving parts, 50 percent less cab shake for added operator comfort and an advanced in-cab monitor system that keeps the operator’s eyes forward during cart acquisition and dump functions.”

Eric Evans, VP of mobile product management for Heil explained the importance of operator comfort and overall simplicity, both from a driver and a maintenance perspective, as key to addressing personnel shortages in the industry.

“We’ve heard from all of our major customers that both operator and mechanic retention has been a primary concern, especially with the increased complexity of modern garbage trucks,” said Evans. “The Command-SST addresses these needs head-on with innovative technologies that both the operator and the maintenance specialists will appreciate.”

He says the Command-SST’s arm functionality allows operators to grab carts in ditches, snowbanks or even carts that have tipped over, all from the safety of the cab. Additionally, the arm has settings that make it easier to grab cans that are positioned close together.

From a maintenance standpoint, the Command-SST arm includes far fewer moving parts and greatly reduced lubrication points that are all accessible at ground level. The arm can also be completely swapped out in an hour.

“From a complexity standpoint, Heil engineers delivered with an arm that

which equates to better payloads and increased productivity. According to Heil, with its Odyssey-inspired hydraulic controls, fleet owners can expect fuel savings on par with a front loader. Plus, with the arm mounted to the body, the Command-SST also frees up valuable frame space for nextgeneration technologies that require additional chassis space.
