Abstract
A working machine, such as an industrial truck, has working hydraulics, a hydraulic steering device, and a spring-loaded brake. The brake has a braking position and a release position and can be acted upon by a brake-release pressure, which is passed in a brake line, so as to be brought into the release position. A hydraulic pump is provided for the supply to the working hydraulics and the steering device and for producing the brake-release pressure of the spring-loaded brake. The brake line of the spring-loaded brake is connected to a delivery branch line, which is connected to the pump, of the steering device.
