Enerpac (A Division of Actuant Corp) has introduced a new hydraulic jacking system rated for heavy lifts up to 200 tons (181 metric tonnes).
The new portable self-contained Pow’R-LOCK hydraulic jacking released by Enerpac features full-time automatic load holding protection for optimum safety in operation, and will be introduced to Australasia at the Queensland Mining Exhibition QME 2014 in Mackay from July 22-24.
PL-Series Pow’R-LOCK portable lifting system is purpose-built to provide safe and secure lifting for heavy off-highway machinery including trucks, tractors, civil engineering machinery and implements weighing up to 200 tons.
Pow’R-LOCK accomplishes its load-holding protection by utilising a patent pending 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 portable 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. Available in two versions featuring strokes of 355mm and 635mm, Pow’R-LOCK portable lift systems are ideal for companies where time and safety are critical factors, such as mining and energy, oil and gas, heavy infrastructure construction and heavy transport.
Enerpac Regional Manager, Australia and New Zealand, Mr Denis Matulin observes that machinery servicing can be a time-consuming and hazardous task if not undertaken properly; 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. The Pow’R-LOCK lifting jack system offers an efficient solution to such problems with its easily manoeuvrable, self-contained design, and can be used in even the tightest locations and over rough terrain so long as recommended safety procedures are followed.
Pow’R-LOCK provides autonomous locking of the load through all stages of lifting and lowering with no operator intervention required to activate or energise the locking system.
Key features of Pow’R-LOCK hydraulic jacking system include: Redundant lowering valves, PO (pilot operated) check and counter-balance to add safety to the retract operation; Pow’R-LOCK locking system providing autonomous protection during lift, lower and hold function; Pneumatic operation for use in potentially hazardous environments; Patented cylinder and control technology providing double-acting lock-nut protection with low collapsed heights; Nitro-carburization providing additional corrosion protection on the cylinder; Simple two-button operation for raise and lower functions; and, Integrated tilt saddle to reduce side loading and extend the life of the jack in extreme situations.
A large base plate, which increases contact with the ground, distributes load, resists tipping and achieves a stability factor, allows Pow’R-LOCK to be classified as a vehicle support stand. An ergonomic six-position handle maximises leverage and hand clearance under vehicles when positioning to a lift point.
Pow’R-LOCK is backed by Enerpac’s extensive product support from national and worldwide networks of local distributors and authorised service centres as well as regional customer and technical service centres.
Enerpac recommends that safety procedures should be followed wherever Pow’R-LOCK is operated, including published safety directions for lifting and cribbing loads.
