Enerpac Cube Jack’s Footprint, Speed and Accuracy Assist PHL Hydraulics
PHL Hydraulics UK has used Enerpac SCJ-50 Cube Jacks to successfully install a 40-ton processing vessel in a busy chemical plant. The cube jack’s small footprint, fast operation and accurate lifting and lowering allowed the vessel to be installed in half the planned project time.
Measuring 80m x 4m diameter, the vessel needed to be raised 1.5m to allow a 1m high platform to be inserted beneath. Supplied with jacking beams, the vessel was initially raised from 0.25m using jack and pack taking 4 hours. At 0.5m, four cube jacks were inserted at each corner. “As the plant was fully operational then using a forklift truck to move cribbing back and forth was impractical. Deploying the Enerpac cube jack meant we only needed the minimum of cribbing to get the vessel to the point where we could switch to the cube jacks,” said Damien Lynch, sales director, PHL Hydraulics UK.
Over the next two hours, the cube jacks raised the vessel to 1.5m and lowered it onto the platform. Precision was critical. The cube jacks achieved accuracy within 2mm during lowering allowing correct alignment of the vessel.
Damien Lynch again, “The Enerpac Cube Jack was fast and really came into its own when lowering. It gave us the control we needed to precisely align the vessel on the platform. Once installed we quickly lowered the cube jacks and the job was complete.”
The Enerpac SCJ-Series Cube Jacks provide users with a safe and efficient method of incremental lifting. The design results in cost savings in mobilisation and manpower as well as cutting the overall time to perform a lift. Cube Jacks are mechanically locked and stable up to their maximum height of 3m, ensuring safety for operators at all times.
Steel cribbing blocks are only inserted once the load is mechanically locked on the cube jack. They are easily aligned in a single movement, providing optimum safety, so the operator does not need to put hands beneath a load suspended by hydraulic pressure.
The cube jack is derived from the proven Enerpac Jack-Up System, but in a vastly smaller footprint allowing it to be used in confined spaces and without the need for electrical controls. The compact size and portability of Self-Locking Cube Jacks offer a powerful solution for numerous applications, such as equipment maintenance, vehicle unloading or jacking a transformer, module, or bridge.
