Hydraulic industrial tools specialist, Enerpac, has launched a lifting system for safer and quicker excavator maintenance
Enerpac’s new lifting system, based on its SCJ-Series Cube Jacks, lifts and holds an excavator’s entire cab, boom and arm – allowing the undercarriage to be safely removed.
Maintenance of an excavator’s swing drive and bearings involves separating the undercarriage unit from the upper body cab and arm, giving access to the swing motor and multiple sets of planetary gears, Enerpac says.
Until now, this process would usually involve at least two service engineers jacking up the body and holding it on stands, which is time consuming and a hazardous practice, the company says.
Enerpac’s cube jack lifting system comprises two pairs of cube jacks providing coordinated hydraulic lifting of loads up to 25 tonne per jack, to a height of 2m.
One pair of cube jacks is positioned under a lifting beam at the rear of the excavator, while the other two cube jacks are located under the arm’s bucket lugs. Each pair of cube jacks is connected to a hydraulic pump to simultaneously lift and lower the excavator body and arm.
“The lifting system has been developed in collaboration with a leading excavator maintenance company, looking for a safer CE-certified approach to removing the undercarriage,” an Enerpac spokesperson says.
“It automatically self-locks so that engineers can work safely under the raised cab without the need for secondary jack stands.
“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,” the spokesperson says.
