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.

Going large – heavy lifts with the Enerpac SCJ-50 Cube Jack.


“The SCJ-50 Cube Jack represents a significant advance in safety, ease-of-use and productivity in compact, portable lifting solutions,” said Peter Crisci, Product Line Director, Enerpac Heavy Lifting Technology. “The incremental system mechanically locks the load as each cribbing block is manually added or removed, instead of being held by hydraulic pressure. Once the mechanical lock engages, the lift cylinder retracts, and another cribbing block can be added or removed. This safer, simplified operation sequence can be accomplished with 50 percent fewer cycles than climbing jacks, yielding a substantial increase in productivity as well,” Crisci noted.

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 16kg steel cribbing blocks can be safely and easily stacked onto the compact Cube Jack base frame yielding a maximum height of 2m. The base frame footprint measures just 502mm x 430mm, making it ideal for portability and restricted operating space. A low 494mm minimum initial jacking height increases flexibility and reduces operational startup time.

The SCJ-50 Cube Jack operates with standard 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.
