Enerpac has introduced the SCJ-50 self-locking cube jack for incremental lifting and lowering of heavy loads.

The compact and portable hydraulic system uses a base lifting frame and self-aligning cribbing blocks to provide high-capacity, stable lifting. Enerpac said that the SCJ-50 is an efficient alternative to climbing jacks with wooden cribbing.

The system has a capacity of 56 tons (50.8 tonnes).

“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 at Enerpac. “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,” added Crisci.

The latest jacking product from Enerpac is based on a similar operating principle to the company’s 125-750-ton (113.4-680.4-tonne) jack-up systems but without the need for electrical controls.
