Four Enerpac Cube Jacks Install Two16t Presses for Bovis Groupe

Faced with installing two 16t presses, one on top of the other, with just 30mm headroom, leading French equipment installer, Bovis Groupe, has used Enerpac cube jacks to successfully complete the installation. By combining Enerpac SCJ-50 cube jacks with load-holding, wooden cribbing and jacking blocks, the presses were lifted and accurately positioned within the space available.

Bovis Centre in Poitiers and Trinstal Equipements in Angers have collaborated on this high-precision, handling project for a manufacturer of high-tech electronics and advanced materials. The technical challenge was the space constraint. Using 3D modelling software, a lifting scenario was developed based on progressive jacking of the upper press to within 30mm of the factory ceiling. From this position it could be lowered onto the second press to complete the presses assembly.

For the vertical lift of the upper press, the Bovis team used four Enerpac SCJ-50 cube jacks connected to a split flow pump, providing synchronised movement of all four jacks. After the initial lift, the press was supported by wooden cribbing while the cube jacks were positioned on jacking blocks and the lift repeated. Once the upper press was at the correct height, Bovis used a 30t hydraulic mover to move the lower press into position beneath the upper press.

“This was a very precise operation and demonstrated the lifting accuracy we can achieve with the Enerpac cube jacks. Thanks to our meticulous planning, and the ease of using the cube jacks, we were able to complete the installation of both presses on the same day,” says Jérôme Lebrequier, Industrial Project Manager, Groupe Bovis.

The Enerpac SCJ-50 Cube Jack can lift 50t up to a height of 2m. It uses a base lifting frame and self-aligning, lightweight steel cribbing blocks to provide high-capacity and stabilized lifting. The incremental system mechanically locks 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.
