The SCJ-100 Cube Jack is a compact and portable hydraulic solution for synchronised incremental lifting and lowering of heavy loads. It uses a base lifting frame and self-aligning, lightweight steel cribbing blocks to provide high-capacity and stable lifting. Steel cribbing blocks have several benefits over wood cribbing, including fewer cribbing components to handle and align, 8 times faster lifting, and higher lifting compared to the traditional cribbing methods.
During sideload testing, four SCJ-100 Cube Jacks were used to lift a 400 metric ton test load. At 2m high, the load was subjected to a side load of 10 metric tons (2.5%) by attaching a cylinder to the load and pushing the load to the full stroke of the cylinder. At 3m (the maximum lift height for SCJ-100), the load was subjected to a side load of 6 metric tons (1.5 %).
“Even during the toughest sideload test the performance of the SCJ-100 was impressive and with enhanced safety,” said Pete Crisci, Product Line Director at Enerpac Heavy Lifting Technology. “By raising the lifting capacity and maximum lift height, we now offer users a way of tackling heavy lifts that would have been impossible before without excessive and time consuming use of climbing jacks with wooden cribbing.”

Up to eighteen 24.5 kg steel cribbing blocks can be safely and easily stacked onto the SCJ-100 Cube Jack base frame yielding a maximum height of 3006 mm. The base frame footprint measures just 655mm x 636mm, making it ideal for restricted operating spaces. A low 558 mm minimum initial jacking height increases flexibility and reduces operational start-up time.
Cube Jacks operate with up to 700 bar (10,000 psi) hydraulic pressure and are compatible with standard pumps, such as the Enerpac Split-Flow Pump that offers the ability to evenly operate multiple Cube Jacks.
The SCJ-100 Cube Jack comes with a storage frame to make tool maintenance and inventory management easier.
