ABSTRACT:
A cable is connected between the dump body of a dump truck and the movable control member of an hydraulic valve to automatically shift the valve from its "raise" position to its "neutral" position when the dump body approaches its uppermost raised position. There is means to prevent inadvertent transmission of forces from the cable to the movable control member to thereby prevent accidental lowering of the dump body due to an inadvertent pull on the cable.
