Hydraulic drives have been on the rise for years - and not without reason. Hydraulics are a real alternative to mechanical gearboxes thanks to their separate design and minimal wear (among other things). The GRANIT Service Centre offers various inspection and repair services:

 

• Axial piston pumps and hydrostatic drives from Bosch Rexroth, Brueninghaus Hydromatik, Linde, Parker, Sauer Danfoss, Bondioli & Pavesi, Kawasaki, Eaton, Vickers and others on request
• Control units (mechanical and electrical control)
• Additional control units (with mechanical, electrical and CAN bus control (Bosch Rexroth only))
