Water, mining, construction, energy exploration, and infrastructure groups are becoming ever-nimbler in moving machinery and plants over significant distances as opportunities decline at one site and open up in more profitable areas. It is where lifting cushions come into play.
One solution for heavy lifts from low levels and soft or confined conditions is the Pronal seamless inflatable lifting cushions from exclusive Australian distributor Air Springs Supply Pty Ltd.
Air Springs Supply is Australia’s leading supplier of air springs and associated pneumatic technology for industrial actuation and isolation and air suspension for heavy truck, bus, rail and hard-working light-to-medium vehicle applications.
These extra-tough cushions – which can lift locomotives, trucks and containers, for example – incorporate the strength of aramid fibre coated with rubber, a combination featuring the same super-tough fibre used in body armour, racing tyres, and racing sails.
Low profile, high capacity
Pronal CLT cushions, in individual capacities of 1 to 65 tons, offer lower profiles than conventional lifting bags with an empty thickness of between 20 and 25 millimetres (mm). Inflated at up to 8 bar, they also provide 20 per cent greater lift capacity than typical alternatives because of their robust construction.
Their interlocking surfaces also deliver stronger gripping when bags are stacked to increase their lifting range beyond individual strokes of 85 to 500 mm, depending on the model and range chosen.
Its remote control prevents the operator from being too close to the lifting area. This inflation system makes the CLT high-pressure air lifting bag essential for safe working.
The range of lifting bags is manufactured from aramid napping coated with elastomer and assembled by vulcanization. They are used in addition to or in replacement of traditional lifting means.
Unlike the hydraulic jack, the pneumatic lifting bag has a larger contact surface when lifting the load. Thus, its stability is perfect, and the thrust is uniformly distributed. Thanks to its low weight and thickness, it can be found in many sectors of activity, such as vehicle recovery, equipment maintenance, handling, or emergency services. This range also includes low-pressure air-lifting bags and stack bags.
