In remote, rugged and sometimes muddy or sandy locations such as trenches it can be difficult to provide crane access overhead or to obtain sufficient clearance and a firm foundation for a lift from underneath. This problem when attempting to engineer the lifting and shifting pipelines, bridges or heavy vehicles is only becoming more and more prevalent as we are continually being restricted by space.
Ironically it is padding which will enable an easier, safer and predicable lift in such circumstances. The expanded ranges of Pronal seamless inflatable lifting cushions from pneumatic specialists Air Springs Supply have provided such a solution. These versatile Pronal lifting cushions can delicately raise loads ranging from pipelines of all types to trucks, tracked vehicles, beams, bridge components, building components, machinery and resource development structures.
Pronal’s newest cushions range from ultra-thin bags (just 20mm thick deflated) that can lift weights of more than 65 tonnes each, to powerful spreading cushions that can exert hundreds of tonnes of force to part plant and machinery components for servicing, or to extract quarried material. These CLP and CLT ranges are complemented by low-pressure CPB Maxi-Lift cushions, which can be used on land and under water, offering greater strokes of up to 700mm (or 1400mm where a pair are employed).
