Hydrostatic drive system for use as operating hydraulic system in drive machine i.e. floor conveyor, has pressure gauge pressurized in direction of flow-through position by control signal, and safety device exhibiting safety position

摘要

The system (2) has a safety device (20) exhibiting a functional position, in which a control signal is guided to a control valve unit, and a pressure gauge (12) is pressurized by a load pressure signal, where pressurization of the control valve unit is controlled using the control signal. The safety device exhibits a safety position (21a), in which the control valve unit is balanced by the control signal, and the pressure gauge is balanced by the load pressure signal. The pressure gauge is pressurized in a direction of a flow-through position by the control signal.
