Technical Examples

Hydraulic lifting device for battery-operated industrial trucks, with at least one hydraulic lifting cylinder, a hydraulic pump working as a pump in the load lifting operation mode, supplying the lifting cylinder with pressure medium and working as a motor in the operation mode of lowering the load, driven by the pressure medium that is displaced by the lifting cylinder, an electric machine coupled to the hydraulic pump, working as an electric motor in the load lifting mode and working as a generator in the mode of lowering the load, a rotation speed control device for the electric machine, the electric machine being controllable in its speed by the rotation speed control device, depending upon the actuation of a set-point transmitter, a lifting valve arrangement in a lifting branch leading to the lifting cylinder, a lowering branch between the lifting cylinder and a connection between a check valve and an entry of the hydraulic pump, a volume flow delimiter in the lowering branch, a bypass valve arrangement that connects an exit of the hydraulic pump with the tank, and at least one further hydraulic consumer, which can be supplied by the hydraulic pump via an assigned control valve, wherein the lifting valve in the lifting branch is disposed downstream from the branching of a conduit to the secondary consumer and the conduit is connectable to the tank via a pressure balance on the upstream side of the control valve.
