SCJ-Series, Self-Locking Cube Jack

Easy-to-use, compact and portable jacking system that utilizes base lifting frames and self-aligning, lightweight steel cribbing blocks, instead of wooden cribben materials. 

Operation is simple:

  1. Connect the Cube Jacks to the Enerpac Split-Flow Pump and select lifting mode on each base lifting frame.
  2. Insert a cribbing block and actuate the Cube Jack until the cribbing  block engages the lock mechanism. 
  3. Retract the jack and repeat the process until the desired lifting lifting height is reached. For the lowering operation select lowering mode on each base lifting frame and reverse the process. The Cube Jack End Block is equipped with an adjustable saddle for initial alignment with the load. All controls except for the main directional valve, which is on the hydraulic power unit, are included on the Cube Jack. 

Manual Cribbing Block Insertion

Cribbing blocks are easily managed by hand and te Cube Jack includes integrated fork pockets and lifting rings for effortless positioning. 

Synchronous Lifting & Lowering

If synchronization is required, the Cube Jack can accommodate stroke sensors and be used with any Enerpac Computer Controlled Synchronous Lifting System. 

Markets & Applications

Applications with a minimum starting height of 494 mm and requirement to lift up to 2067 mm.

Split-Flow Pumps
Enerpac recommend to use the SFP-Series Pumps with multiple outlets with equal oil flow. For lifting and lowering applications on multiple points, Split-Flow Pumps are a far better alternative than using separately operated pumps.

Lightweight Cribbing Blocks
11 Cribbing Blocks are included with a SCJ-50 Cube Jack. A maximum of 11 cribbing blocks can be used on a single Cube Jack. Cribbing Blocks can be manually inserted into the Cube Jack by one person. Spare cribbing blocks can be ordered separately.
