Enerpac DLS Series Dozer Lift System

The Enerpac DLS Series Dozer Lift System - developed particularly for CAT D10s and D11s - features four-point custom synchronous lift technology to provide safe, level lifting and lowering for track and side frame maintenance of the dozers, while using single-operator lifting.

The system’s two separate lifting units, incorporating the synchronous PLC controlled load sensing and lifting technology, can be swiftly and easily positioned at opposite ends of a dozer. Each lifting unit includes two hydraulically operated jacks with motorised locking rings. The jacks are bolted to a rolling cart with fork pockets and retractable wheels for easy and precise positioning of the units.

Lifting and lowering of the jacks can be paused at any point, and a built-in alarm system will stop the synchronous lift in the event of malfunction. Lifting speed is approximately 46 mm/min, allowing users to finish a lift quickly to reduce equipment downtime.

The front and rear lifting jacks are driven by a hydraulic power unit (HPU) and controls which includes a 25-foot pendant for operator mobility and safety during lifts. The entire HPU and controls are contained in a rolling cabinet which includes storage for cable reels and hoses.

The controls include PLC and software to monitor and control a maximum of four lifting points simultaneously, and has a touch screen mounted inside the cabinet, enabling the operator to remotely monitor key lifting information, such as lifting height and load. A single hydraulic unit has the capacity to operate up to six lifting units.
