Self-Locking Cube Jacks
The Self-Locking Cube Jack is a safer, more efficient alternative to the jack-and-pack method with wooden cribbing. It also features a small footprint and is useable in confined spaces, providing a stable lift to nearly 10 feet. Jobs are completed more efficiently due to simplified operation sequence with 50% less cycles than climbing jacks.
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.
