Super-tough cushions get to the bottom of tricky lifting problems
Aramid textile-coated reusable Pronal CLT lifting cushions in capacities up to 65 tons per unit Mining, construction, energy exploration, and infrastructure groups are becoming ever nimbler in moving plant, people, and resources over major distances as opportunities decline at one site and open up in more profitable areas. This has led to a new generation of transportable technologies and plant, including portable buildings and transportable facilities that need to be safely lifted for trucking to new destinations. “Such vital facilities can include accommodation, maintenance, engineering, testing, and medical facilities, extending through to containerised energy management and electronic technologies associated with electrification and automation of sites,” says Pronal elastomer engineering specialist Vinh Lam, of Pronal exclusive Australian national distributor Air Springs Supply Pty Ltd. A problem associated with such lift and shifts is creating access gaps under loads for safe lifts onto transport, particularly where space around the load may be limited, or site conditions may involve soft or variable substrates that preclude the initial use of hydraulic or mechanical lifts with high point loads. Even on hard surfaces, using crane or forklifting techniques to create the initial lifting gap may damage hard concrete or tarmac surfaces, unless a working gap is first created for optimally safe access beneath heavy structures, or structures that may have been in place for some time. Pronal lifting cushions gently and safely lift multiple structures and fixed and mobile plant, including containerised plant. “Heavy processing equipment and portable structures often need to be raised to a low height to enable safe clear access so forklift tynes, crane strops, or standard lifting equipment or vehicles can do their work of loading onto transport,” says Vinh Lam. “The lifting gap is important, because it enables heavy lifting equipment to get through beneath the base of the load […]
