Softly, softly with new lifting cushions

Awkward site conditions – including soft ground, confined trenches, crash recovery areas and uneven earthworks – can create hazards for conventional lifting technologies.

Often there is insufficient room overhead to employ suitable cranes, even if they can be brought overland to a remote site.

Sometimes also there is insufficient stability underfoot to employ lifters that produce high point loads both on the ground and on the object being lifted.

One solution to the problems can be seamless inflatable lifting cushions from Pronal, an innovative elastomer manufacturer whose products are distributed in Australia by Air Springs Supply Pty Ltd.

The Pronal range of CLT lifting cushions from Air Springs Supply can delicately raise loads ranging from heavy vehicles, pipelines and plant through to beams, bridge components, building components, machinery and resource development structures.

Pronal products have been proven worldwide in projects as diverse as lifting locomotives and heavy vehicles through to submersible types used, for example, to raise artefacts from the ocean liner Titanic, sunk nearly four kilometres deep in the Atlantic.

The range of lift cushions, featured on the Pronal website: www.pronal.com.au 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. Complementary low-pressure CPB Maxi-Lift cushions can be used on land and under water, offering greater strokes of up to 700mm (or 1400mm where a pair are employed).

Air Springs Industrial Products Manager Mr James Maslin says the Pronal bags combine the advantages of high durability and power with gentle, precisely controlled lifting that can spread the load over broader surfaces of the object being lifted, rather than focusing the power on point loads.

They can be used in confined spaces underneath inaccessible loads ranging from engines and plant, through to foundations of bridges, buildings, machinery, pipeline structures and resource development rigs requiring lifting for inspection and repair.
