Maximize StoryMinimize StorySoftly, seamless lifters provide controllable power even on awkward sites - October 2011

Media Release - AIR SPRINGS - October 2011

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 the global Pronal elastomer product organisation, distributed n Australia by Air Springs Supply Pty Ltd.

The Pronal range of CLP 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 crashed aircraft, 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.

CLP cushions, featured on 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 General Manager Mr Simon Agar 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.

"Sometimes cranes, slings or cylinders may not be the right choice for lifts with particular technical challenges in terms of lifting surfaces or surfaces to which lifting force is to be applied. Where companies are contemplating considerable investments in custom-engineering conventional lifting platforms, it may be well worth considering the simple principle of pneumatic actuation," he said. This can be particularly so when working in confined spaces, such as trenches and mines, where there is little room beneath pipelines and plant. Features of the Pronal product include:

  • As well as straight lifting, they can be used for pressing, clamping, tilting and guiding
  • Strokes from 70-585smm (CLP), with longer strokes provided by combinations of cushions
  • In addition to standard sizes, specific sizes and shapes can be made to order to suit particular applications.
  • Ease of use, with inflation either by compressor or simple air cylinders
  • Inflation pressures up to eight bar, regardless of stroke (CLP models - CPB pressures vary from under one bar, depending on model)
  • Construction from threaded layers coated with chemical resistant elastomer, hot vlucanised under pressure in one operation.
  • Non-slip surface providing maximum friction when stacking two cushions
  • Control systems tailored to particular uses

Pronal equipment such as the PAC series of lifting cushions can be supplied with trailers, lifting bases and control systems developed to the demanding standards of Pronal's world-wide customer base, including military and civil aviation applications.

Media Release - AIR SPRINGS - July 2011

A range of collapsible pipe stoppers from Air Springs Supply can compactly fit around obstacles, corners and into previously inaccessible areas of surface, underground and underwater pipelines.

The custom-fabricated and stock ranges of Pronal Uni-Plug stoppers - especially recommended for low-pressure applications - are water tight and easy to install for maintenance, testing and emergency tasks.

These include pipe repair, insulation of areas for welding, sealing of mine levels and isolation of risers in factories, power plants, water utilities and other industrial, resources and municipal infrastructure.

Produced in stock diameters from 50-1600mm - with larger custom-fabricated sizes available for particular applications - Uni-Plugs are a tough advanced technology product from the internationally respected Pronal organisation, which produced the enormously strong inflatable bags used to lift sections of the liner Titanic from nearly four kilometres deep in the Atlantic.

Pronal also manufactures inflatable emergency, rescue and maintenance equipment used by industrial, Military and civil defence organisations worldwide, including transportable water and fuel tanks and lifting cushions used to raise equipment ranging from crashed aircraft to mining plant needing maintenance.

The easily transported and reusable Uni-Plug range is made from reinforced fabric coated with synthetic elastomer, says Mr James Maslin, Sales Manager for pneumatic actuation and isolations specialists Air Springs Supply, which is national distributor for the Pronal range.

"Space is often at a premium in pipelines serving complex industrial and infrastructure structures - such as desal and municipal water plants, power plants, mines and offshore rigs - and spaces available can be awkward for conventional stoppers to reach," said Mr Maslin. "One of the beauties of the Uni-Plug system is that it can be collapsed into confined spaces then inflated at the place where it is needed. The quality of the product provides top levels of safety and reassurance, with Pronal products having been proven worldwide in both military and civil applications," said Mr Maslin, whose organisation has more than 25 years specialist national experience in applying pneumatic actuation and isolation technologies.

Uni-Plug ranges are complemented by optional accessories including inflation lines, flexible bypass hoses, vacuum indicator, thermal protection, control valves and gauges. Different types of Pronal stoppers are available for high pressure applications.

Information about Pronal products can be obtained through the Pronal website of Air Springs Supply Pty Ltd, www.pronal.com.au. Air Springs Supply's complementary website, www.airsprings.com.au is one of Australia's most comprehensive guides to pneumatic actuation, isolation and suspension.

Media Release - AIR SPRINGS - May 2011

Some of the world's most advanced flexible lifting bags and lifting cushions are available throughout Australia from Air Springs Supply Pty Ltd for applications in mining, safety and rescue, construction, civil engineering, industrial, maritime, petrochemical and transport industries.

Pronal flexible lifting bags are manufactured by the same company that produced the enormously strong inflatable bags used to lift sections of the liner Titanic from nearly four kilometres deep in the Atlantic. Their power, safety and reliability is demonstrated by their use internationally in the safety kits of fire and rescue services, says Air Springs Supply General Manager Mr Simon Agar.

Manufactured from plastomer and elastomer coated fabrics vulcanised in a vacuum at 140°C, Pronal lifting cushions are designed for loads up to 70 tons. Normally inflated with air or any other fluid (water, oil, glycol, etc) depending on the application, Pronal flexible products are designed to perform mechanical functions such as pushing, pressing, guiding, clamping, blocking, damping, lifting, moving, wedging and materials handling.

They can be used for tasks ranging from precise splitting of mineral blocks and heavy structures, to lifting of heavy vehicles for service and safety reasons. The cushions are also easy to integrate into mechanical systems, such as presses, moulds, conveyors, handling robots, lifting tables and other machinery.

Advantages include:

  • compact when deflated, for easy transport
  • reduced overall dimensions permit use where low height (down to 20mm) is required
  • thrust evenly distributed over a wide area (vs point loads of alternative systems)
  • large surface area (enhanced by dimpled/textured rubber surface)
  • an asset in many lifting and pressing applications
  • very easy to adapt to tasks, requiring minimal setup
  • no costly additional equipment required where standard factory air or mobile compressed air available
  • no sliding seals, with ongoing maintenance
  • high lifting force
  • speed and safety in operation
  • light weight, ideal for use in latest lightweight process lines or for mobile operations in construction, engineering, mining and maintenance

Mr Agar says the highly diversified range provides an easily transported and cost-efficient alternative to hydraulic actuation and craneage across a wide range of industries.

Using technology proven worldwide in land and sea operations, Pronal products are available in standard square and rectangular shapes (100 to 1000mm side dimension), one or more stages, and up to 7 bar inflation pressure (12 models).

Customised rectangular, tubular or round shapes of diverse sizes are available on order, with multiple accessories available to adapt equipment to different industrial, engineering and physical requirements.
