Jack-up system
02 March 2017
Heavy lifting equipment specialist, Enerpac, has launched an incremental multi-point jack-up system designed for heavy lifting applications.
The company says its new JS-Series jack-up system is able to simultaneously lift and mechanically hold loads, offering operators a safe and efficient lifting method. Each lifting tower has a capacity of up to 750 tonnes and a lifting height between 6-20 metres. They have up to 5 percent side load capacity (depending on model and lifting height). Lifting and lowering is done using a computer-controlled unit for greater precision, while the control unit’s synchronous technology maintains the balance of the load, says Enerpac.
Self-contained hydraulics in each leg unit mean uncluttered work areas. Loads are lifted in increments as steel boxes, called barrels, are stacked together to form lifting towers to mechanically hold the load. A typical system setup includes four jack up units positioned under each corner of a load.
Target applications include: bridge construction and demolition; port crane lifting; mining shovel undecking;
top side lifting; and ship hull block installation.
