A new heavy duty lifting system is being introduced by Enerpac that enables the power and precision of hydraulics to be used to safely move massive weights over longer distances.
Stage Lift systems, in capacities from 10-1000 tonnes per lift point, overcome limitations imposed by hydraulic cylinder strokes that are too short for some jobs.
The compact but powerful 700 bar Stage Lift systems - operating in multiple steps of 50-1219mm stroke per stage - can be remotely, manually or computer synchronized to lift, hold and lower large objects in applications such as:
tank jacking and lowering
hoisting buildings, structures, infrastructure and platforms
maintenance of heavy plant and equipment
ship lifts and heavy cargo positioning
synchronized jacking within tolerances of less than 1mm
Instead of operating like standard cylinders that project their plunger upwards under a load, Stage Lifts project their plunger downwards when lifting. This downward force lifts the cylinder body, its spreading plate and its load clear of the ground so cribbing blocks can be placed under the spreading plate that is integrated into the cylinder. When the load is supported by cribbing blocks, the plunger is retracted so further blocks can be placed under it and it can press down again to lift the load a stage further (see steps 1-4 in graphic accompanying this story) The process can be repeated multiple times, says Anders Mangen, Business Unit Manager of the Australasian operations of Enerpac.
Capable also of operating horizontally, Stage Lift Systems are employed to move large weights where other methods such as cranes are impractical, cannot gain access to lift, or do not offer the controlled precision of hydraulics.
Stage lift technology - introduced to Australasia in Enerpac’s new E325e Industrial Catalogue - has been proven worldwide in applications as diverse as industrial and resources projects and the Athens Olympic Stadium (where the system was used horizontally to move the arched roof into its final position). The system can also be employed in climbing units.
Stage Lift Systems are among the world’s most advanced, safe and versatile high-force industrial lifting, pumping and heavy materials handling technologies being introduced to Australasia as Enerpac stages its biggest-ever expansion Down Under.
Innovations in the new Enerpac range from low-profile cylinders for inaccessible places through to sophisticated Synchronous Lifting systems that one person can operate from up to a kilometre away to lift and manoeuvre giant weights (including bridges, turbines, draglines and drilling platforms).
Enerpac’s largest range ever of time and cost-saving precision tools also includes new families of aluminium cylinders weighing half their steel equivalents; new generation ZE and ZU electric pumps with fewer moving parts that save power while extending reliability in repetitive processing and handling tasks; and new families of professional bolting technology.
