Air Springs Supply offers a versatile range of Pronal inflatable lifting cushions and pipe stoppers for various installation, maintenance and dewatering operations.
Pronal’s seamless CLP lifting cushions can delicately raise pipelines, pumps and associated dewatering equipment, providing an easy, safe and predicable lift in rugged, remote or particularly muddy or sandy locations with restricted access for cranes. These lifting cushions can also hoist all types of trucks, tracked vehicles, beams, bridge components, building components, machinery and resource development structures.
Air Springs Supply National Sales and Marketing Manager Mr James Maslin explains that the superbly engineered lifting cushions have been developed by French elastomer specialists Pronal for industrial, municipal, military and civil tasks using materials so tough and durable they can lift tanks or split rocks in quarries and mines.
Pronal offers lifting cushions in several standard models as well as in custom engineered sizes and shapes to suit specific application requirements.
Pronal’s 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 lift loads, separate plant and machinery components for servicing, or 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 for a pair).
Pronal pipe stoppers
Pronal’s family of pipe stoppers including the Vari Plug range is used for maintenance, testing and emergency tasks.
According to Mr Maslin, the lightweight, easily manoeuvred and easily positioned stoppers are typically employed for applications ranging from routine pipeline maintenance and testing through to emergency stopping of polluted water.
Designed to fit pipe diameters of 70-1500mm in industrial, resources, municipal and infrastructure applications, the tough, polyamide-reinforced Vari Plug stoppers are inflated by compressed air on remote sites and can be used to seal concrete, plastic and metal pipelines carrying potable water, stormwater, waste water and non-petroleum based solutions. The pipe stoppers may be employed to block a leak from entering the surrounding environment or waterways, or provide a tight seal upstream of a pipeline fault so it can be repaired in a safe, clean and clear environment.
Pronal’s OPAP and OFR Pollu-Plug stoppers provide ongoing protection against contamination of waterways from spills into water and sewerage lines. Permanently fitted in water and sewerage lines, these stoppers are ready for instantaneous inflation by remote triggering as soon as an emergency arises in industrial, civil and municipal applications.
Pollu-Plugs are available in diameters of 100-1000mm and lengths of 450-2050mm (both measurements when empty). Custom sizes can be produced on request.
