Abstract
PURPOSE: To prevent the occurrence of accident in a remote controller by restoring a direction switch valve to neutral position as well as raise the operability of the operating lever of the remote controller by reducing the loss width for the insensible region of the direction switch valve of the operating lever.
CONSTITUTION: When solenoid valves 12W14 are off, both chambers 16 and 17 are connected with each other through a valve 13, and the movement of a pilot piston 15 is freed to enable a direction switch valve 6 to be freely controlled by a manual operating lever 5. Then, when the solenoid valve 12 is off and the solenoid valves 13 and 14 are on, the piston 15 is fixed in the neutral position. Also, when the solenoid valves 12 and 13 are on and the valve 14 is off, the piston 15 moves to the left side and the direction switch valve 6 is switched to the position A. In such a remote controller, the control circuit 20 consists of a limiter circuit 23 transmitting an output by greatly changing the command signal of a position setter 22 in the neighborhood of the neutral position of an operating lever 21, a comparator 25, a safety circuit 30, and a manual auxiliary circuit 31.
