Designed for keeping a trailer level when it is not connected to the truck, the landing leg is a key component of the transport equipment market – particularly since it is crucial to ensuring safety. As Australia’s supply chain becomes increasingly competitive, combining safety with fast-moving equipment is now prompting many a fleet operator to invest in next generation automated systems.
Perth’s WA Bos – the Australian distributor of the PTS50, a pneumatic trailer leg built in Ireland – delivers a hybrid form of automatic landing leg that will put the traditional hand-winding leg assembly to bed. “Instead of operators physically cranking a landing leg up or down to its required position, a job that ordinarily takes three to four minutes at a time and puts the person’s muscles and joints at risk, the PTS50 just takes seconds to complete the movement – all at the push of a button,” says Bob Wright, owner of WA Bos. “The system is built to work off the same air supply used for brakes and air suspension, and increases operational efficiency by speeding up the coupling and uncoupling process. That is saving work time and fuel.”
Other PTS50 advantages include significant improvements to driver health and safety. “Since there are just two buttons that either raise or lower the landing legs, it is the safest landing leg system going around,” he says. “It’s extremely user-friendly and can be operated by anyone. There is no risk of physical issues with the PTS50, which long-term can result in employee retention and fewer workers’ compensation claims.
“On the maintenance front, the PTS50 can save on costs as it has just two moving parts with no gears or lube, with each leg set to last the lifetime of the trailer. It’s also 15kg lighter than conventional cranked landing legs as there are no handling gears or cross shafts.
“Cosmetically, each PTS50 leg is identical, enabling it to be fitted both nearside and offside and also allows side skirts and wind deflectors to be installed down both sides of the trailer, allowing for optimum aerodynamics. The user can even fit up to four legs (two in the front and two at the rear) in one trailer to improve safety and stability.”
The PTS50’s use of high-strength steel offers unrivalled possibilities for equipment manufacturers and users, says Bob. “The tight bending radius increases scope for improved designs with most components constructed by bending instead of welding,” he notes. “The PTS50 also combines excellent cold-forming properties and an extremely high impact strength that exceeds standard requirements. It’s also cut to the specifications of all end users, so that operator can have it fitted right away.”
According to Bob, the system is both the present and future of landing leg technology in Australia. “The PTS50 has undergone stringent field-testing over the past few years. The system has a positive effect on almost every operational aspect of a fleet – be it driver recruitment and retention, safety, maintenance, aerodynamics, idling reduction time and efficiency.”
