ル装置。The solenoid valve is driven by the deviation between the instruction signal from the position setter linked to the operating lever and the position signal from the position detector which detects the position of the pilot piston which is linked to the directional control valve and controls the pilot piston. and a neutral position detection circuit that stops the operation of the control circuit and automatically returns the directional control valve to the neutral position when a neutral position instruction signal is output from the position setting device. The remote control device for equipment includes a timer circuit that is activated when the neutral position signal is output to stop the operation of the neutral position detection circuit for a certain period of time, and the direction switching is performed by the control circuit when the neutral position signal is output. A remote control device for hydraulic equipment characterized by forcibly controlling a valve to a neutral position.
