  • Turning brake controlling system for use in power shovel
    Patent number: 5182713
    Abstract: A turning brake controlling system for use in power shovel arranged such that even when a microprocessor for controlling the operation of the turning brake actuator means malfunctions the turning brake can be applied without fail by shifting a turning lever to its neutral position, and the upper turning body can be stopped at a predetermined position without being subjected to the influence of external forces such as gravity, etc. when it is turned slowly on a slope. The turning brake controlling system has a turning lever signal transmitter (1) adapted to output a turning lever signal "a" when the turning lever is shifted from its turning position to its neutral position, and a turning brake actuating signal generator (2) adapted to receive the turning lever signal and output a turning brake actuating signal (h) to a turning brake actuator means (3).
