Enerpac Raises the Bar with 400t Self-Locking Cube Jack Lift

Enerpac Heavy Lifting Technology has successfully completed side-load stability testing of the SCJ-100 (Self-Locking Cube Jack) while performing a 4-point lift with a 400t load up to 3m at its factory in Hengelo, the Netherlands. The SCJ-100 raises the bar for cube jack lifting from 2m to 3m and doubles the lifting capacity compared to the smaller SCJ-50 Cube Jack.

The SCJ-100 Cube Jack is a compact and portable hydraulic solution for synchronised incremental lifting and lowering of heavy loads up to 100t. 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, lifting up to 8 times faster, and lifting higher than using traditional cribbing methods.

During sideload testing, four SCJ-100 Cube Jacks were used to lift a 400t test load. At 2m high, the load was subjected to a side load of 10t (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 the SCJ-100, the load was subjected to a side load of 6t (1.5 %).

“Even during the toughest sideload test the performance of the SCJ-100 was impressive and enhances safety” says Pete Crisci, product line director, 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 24.5kg 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 space. A low 558mm minimum initial jacking height increases flexibility and reduces operational start-up time.

Cube Jacks operate with up to 700bar (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.
