Abstract

A working machine, such as an industrial truck, having a spring-loaded brake having a braking position and a release position and controlled by a brake valve producing a brake-release pressure. The brake valve is operatively connected to a service brake input device, such as a brake pedal, and can be acted upon in the direction of a reduction in the brake-release pressure arising at the spring-loaded brake when the service brake input device is actuated. It being possible, on actuation, for the service brake input device to be operatively connected to a pre-stressed spring device, which is operatively connected to the brake valve and can be acted upon in the direction of an increase in the spring force on increasing actuation of the service brake input device.
