Enerpac has announced the cube jack lifting system for 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.
During maintenance of the excavator’s swing drive and bearings, the undercarriage unit must be separated from the upper body cab and arm to give access to the swing motor and multiple sets of planetary gears.
The Enerpac cube jack lifting system offers a safe, CE-certified approach to removing the undercarriage. It comprises two pairs of cube jacks providing coordinated hydraulic lifting of loads up to 25-ton per jack to a height of 6.5 ft. 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.

“The excavator lifting system has been developed in collaboration with a leading excavator maintenance company looking for a safer CE-certified approach to removing the undercarriage. It automatically self-locks so that engineers can work safely under the raised cab without the need for secondary jack stands,” said an Enerpac spokesperson. ‘It has been well received especially for its safety, secure load holding, precision lifting and lowering and quick and easy set-up which make it attractive to users and customers alike.”
