Compact, Self-Locking Jack


Enerpac, a global market leader in heavy lifting technology and high-pressure hydraulics, announces the SCJ-Series Self-Locking Cube Jack, a new compact and portable hydraulic solution for incremental lifting and lowering of heavy loads. The SCJ-50 Cube Jack uses a base lifting frame and self-aligning, lightweight steel cribbing blocks to provide high-capacity and stabilized lifting–offering a safer, controlled and more efficient alternative to climbing jacks with wooden cribbing.


The SCJ-50 Cube Jack is based on an operating principle similar to Enerpac’s proven 125-750 ton Jack-Up Systems, but in a vastly smaller footprint and without the need for electrical controls. Up to eleven 35-lb. (16kg) steel cribbing blocks can be safely and easily stacked onto the compact Cube Jack base frame yielding a maximum height of 79 inches (2 m). The base frame footprint measures just 19.8 x 16.9 in (502 x 430 mm), making it ideal for portability and restricted operating space. A low 19.4-in. (494 mm) minimum initial jacking height increases flexibility and reduces operational startup time.


The SCJ-50 Cube Jack operates with standard 10,000 psi (700 bar) hydraulic pressure and is compatible with standard Enerpac pumps, such as the Split-Flow Pump that offers the ability to synchronously operate multiple Cube Jacks.


Crisci added that the compact size and portability of the Self-Locking Cube Jack offers a powerful solution for numerous applications, such as equipment maintenance, vehicle unloading or jacking a transformer, module, or bridge.
