Low-pressure cylindrical lifting bags that can smoothly and continuously raise loads of up to 12 tons by as much as 1000mm are being introduced by Air Springs Supply Pty Ltd for diverse industrial, resources and emergency uses.
Pronal CLC inflatable cushions offer stable continuous lifting for tasks such as vehicle maintenance, moving and positioning machinery, turning over heavy loads, locking and holding machinery and on-site repair and rescue operations on soft ground, sand, irregular surfaces, mud and snow.
The readily portable and light (2-13kg, depending on model) lifting bags require an insertion height of less than 50mm before being quickly inflated by low-pressure compressed air at 1bar to achieve high lifting heights required for moderate loads including cars, trucks, 4wds, farm and service machinery and even small aircraft.
Easily transported to remote areas by helicopters, light aircraft, 4wd and automotive service vehicles, CLC bags feature robust neoprene coated construction ideal for rescue and recovery operations and repeated operation in remote and aggressive environments, including mining and energy exploration and production sites.
The four models of CLC low-pressure lifting bags – 3, 5, 7 and 12-ton, all with handling straps – complement Air Springs Supply’s broader range of seamless inflatable Pronal lifting bags, including CLT lifting cushions, which can individually handle lifting loads of 65 tons.
"A beauty of all Pronal bags – besides their extraordinary tough construction, which is relied upon by the military and civil aviation – is they can be used in conjunction with other types of lifting bags required for particular jobs. They apply lifting pressure evenly and safely across the lifting surface and the load, avoiding point loads and instability arising from variable surfaces encountered on many exploration, development and construction sites," says James Maslin, National Sales and Marketing Manager for Air Springs Supply, which is national distributor for Pronal products.
CLC lifting bags offer:
- Constant lifting power during the entire lift
- Safety factor of 3 (bursting pressure V working pressure)
- High burst pressure
- Non-bulging, flat surfaces
- ¼" inlet and safety relief vale
- Accessories including deadman controllers, inflation hoses, adaptors, shut-off unit and pressure regulator
