Enerpac Announces Lifting System for Safer Excavator Maintenance

Enerpac has announced a lifting system for safer excavator maintenance. Based on Enerpac SCJ-Series Cube Jacks, it enables lifting and holding of the entire cab, boom and arm, allowing the undercarriage to be safely removed, according to the manufacturer. The Enerpac cube jack lifting system offers a CE-certified approach to removing the excavator undercarriage for swing drive, bearing and planetary gears maintenance. It comprises two pairs of cube jacks providing coordinated hydraulic lifting of loads up to 25T per jack to a height of 6.5 feet. Two cube jacks are positioned under a lifting beam at the rear of the excavator, while two cube jacks are located under the arm’s bucket lugs. Each pair of cube jacks is connected to a hydraulic pump to synchronously lift and lower the excavator body and arm.

Lloyds witness tested to 125% of maximum working load, the incremental cube jack lifting system is self-locking to support the load as each cribbing block is manually added or removed, instead of being held by hydraulic pressure. Once the mechanical lock engages, the lift cylinder retracts, and another cribbing block can be added or removed.
