Abstract
PURPOSE: To cause a lever control direction to always coincide with a running direction, by a method wherein a running hydraulic circuit is switched through detection of a position of a running lever and revolving angle of a turning table and a running device and through discrimination of the lever position pointing to a forward or a backward direction facing the body of a vehicle for the running lever.
CONSTITUTION: In the relation between a running mechanism 11 and a revolving mechanism 12 of a vehicle, detectors LPX, LPY, RPX, and RPY detects positions of right and left running levers RL and LL, and then, a detector AS detects a revolving angle θ of a turning table to transmit a signal Vθ. From the position of the lever and the revolving angle θ, a left running discriminating circuit LD and a right running discriminating circuit RD in a controller CE discriminate whether the position of the lever points to a forward direction or a backward direction facing the running mechanism 11 of the body of vehicle. The discriminated signal is inputted to a switching circuit CH which switches a circuit to left and right hydraulic motors LM and RM to coincide the control direction of the lever and the running direction of the vehicle with each other.
