The company says its Pow’R-LOCK portable lift system has full-time, automatic load holding protection through all stages of lifting and lowering, and needs no operator intervention to activate its locking system.

Pow’R-LOCK uses a control system that maintains the position of a rotating locking collar near the cylinder base, providing a mechanical lock regardless of cylinder movement and control cycle.

The heavy-duty lifting system integrates into a rugged mobile cart with a high capacity and compact 700 bar (10,000 psi) hydraulic cylinder and an air-driven hydraulic pump unit with complete valving and control systems. Enerpac says the units, the two versions of which feature strokes of 356mm and 622mm, "are  ideal for companies where time and safety are paramount, such as mining and energy, oil and gas, heavy infrastructure construction and heavy transport".

"Machinery servicing can be time-consuming and hazardous task if not undertaken properly," Enerpac Regional Manager, Australia and New Zealand, Denis Matulin says. "Frustrating problems can arise both in workshop situations where space is at a premium, and in remote situations where normal plant services and lifting surfaces are not available.

"A solution to such problems is offered by the easily manoeuvrable, self-contained, Pow’R-LOCK lifting jack system," Matulin says, "which can be used in even the tightest locations and over rough terrain where recommended safety procedures are followed."

"Pow’R-LOCK is unique in that it provides autonomous locking of the load through all stages of lifting and lowering. No operator intervention is required to activate or energise the locking system — they just lift or lower the load. If anything hazardous occurs, the Pow’R-LOCK system is there to hold the load."
