A simple solution for incremental lifting, climbing Jacks overcome the usual limitation of lift height imposed by the jack’s plunger stroke length. Large objects, such as oil tanks, can be lifted, held and lowered for maintenance without sending for a crane. We rent the Enerpac BLS 1506 which has a lifting capacity of 150-tons per cylinder.

The Self-Locking Cube Jack system automatically mechanically locks after the lifting or lowering stroke. Self-aligning steel cribbing blocks save time, improve side load, and eliminate the need for wooden cribbing materials. The cribbing blocks are lightweight and can be handled manually.

Engineered Rigging’s Self-Locking Cube Jacks include an end block with adjustable swivel saddle which allows fine adjustment during set-up: 1.97-inch screw extension.
