Enerpac recently introduced the DLS Series Dozer Lift System for servicing and maintaining 250,000-pound dozers in various mining and construction applications. Designed specifically for the CAT D11 and D10 dozers, the lift system is ideal for track and side-frame maintenance while utilizing single-operator lifting.
The dozer lift features a four-point custom synchronous lift system for safe load control, with two separate lifting units that can be moved into position at opposite ends of a dozer. Each lifting unit includes two hydraulically operated jacks with motorized locking rings for safe operation. The jacks are bolted to a rolling cart with fork pockets and retractable wheels for easy and precise positioning of the units.
The front and rear lifting jacks are driven by a hydraulic power unit (HPU) and controls that include a 25-foot pendant for operator mobility and safety. The entire HPU and controls are contained in a rolling cabinet that has storage for cable reels and hoses. The controls also include a programmable logic controller (PLC) and software to monitor and manage a maximum of four lifting points simultaneously with a color touchscreen mounted inside the cabinet. A single hydraulic unit has the capacity to operate up to six lifting units.
Lifting and lowering of the jacks can be paused at any point, and the system will automatically secure the load mechanically until the operator is ready to begin lifting or lowering the dozer again. A built-in alarm system will stop the synchronous lift in the event of malfunction. Lifting speed is approximately 1.8 inches per minute.
Regardless of weight distribution, the system is designed to lift and lower a dozer synchronously between all lift points. It will also fit beneath dozers with 90-percent track wear, providing enough height clearance to perform track maintenance.
