The Enerpac SC-Series Cube Jacks are a lifting system for excavators and is capable of lifting loads up to 25 tons per jack to a height of 6.5 feet.
The Enerpac system offers a safer, CE-certified, approach to removing the undercarriage, according to the company. Two steel cribbing blocks are positioned under a lifting beam at the rear of the excavator, while two, self-aligning and self-locking 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.
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.
