Jack-Up Systems

Enerpac’s J-Series of jack-up systems features a multi-point, synchronous heavy lifting system that typically includes four jack-up units, each with a hydraulic lifting cylinder, positioned under each corner of a load. Boxes are slid into the system to form lifting towers which lift the load in increments and hold it at the desired height. The lifting and lowering functionality of our jack-up systems are managed via a hand-held computer control unit that optimizes control and safety. A key feature of a jack-up lifting system is its compact footprint.

Precise Control & Optimized Safety

Our jack-up systems are operated and precisely controlled by a computer control unit which makes them ideal for a variety of demanding heavy lifting projects. Each unit's lifting and lowering operations occur simultaneously, and the computer control unit's synchronous technology maintains the balance of the load.

Key features of the Enerpac JS-Series of jack-up systems include:

  • Automatic and manual lifting settings

  • Synchronization of multiple networked lift points

  • Center of Gravity calculation

  • Overload & stroke alarms

  • Emergency stop switch at jack-up units and controls

  • Self-contained hydraulics in each jack-up unit enable an uncluttered (and safer) work area

  • Automated load balancing
