Rexroth is a drive & control company offering drive and control technologies, both specialised and integrated. Rexroth is a wholly-owned subsidiary of robert bosch gmbh. Mobile controls are control and safety systems for drive and working hydraulics of mobile equipment. Rexroth offers the hydrostatic steering units lagu and lagz from their mobile hydraulics division. These are steering units with automatic flow reduction for reducing the actuating force in the event of failure of the oil supply. Quite often, this is sufficient for maintaining the limit values for manual steering. In many cases, it is possible to forego a second oil supply in the event of an emergency.
