行制御装置。 In a backhoe A, a swinging machine 5 with a drive unit 7 arranged above the running machine 3 is connected to the moving machine 3 so as to be freely rotatable left and right, which is driven by a traveling hydraulic motor 1 that can freely rotate in forward and reverse directions. A sensor S for detecting the rotation phase of the aircraft body 5 is provided, and a hydraulic control valve 16 for controlling the operation of the hydraulic motor 1 for traveling and the same valve 1 disposed in the driving section 7 are provided.
A switching mechanism 13 is provided between the travel lever 10 for operating the lever 6 and the switching mechanism 13 that can selectively switch the transmission of the operating direction of the lever 10 operation to either forward or reverse, and prevents both forward and reverse operation when in neutral. A traveling control device for a backhoe which is arranged to control the switching operation of a switching mechanism 13 based on the detection result of a sensor S.
