Stage Lifters safely move massive weights further
new heavy duty lifting system enables the power and precision of hydraulics to be used to safely move massive weights over longer distances. Stage Lift systems, in capacities from 10-1,000t per lift point, overcome limitations imposed by hydraulic cylinder strokes that are too short for some jobs. The compact 700 bar Stage Lift systems operate in multiple steps of 50-1,219 mm stroke per stage. It can be remotely, manually or computer synchronized to lift, hold and lower large objects in applications such as hoisting buildings, structures, infrastructure and platforms. 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. Enerpac’ s Stage Lifters can also be operated horizontally and so are employed to move large weights.
