Abstract
PURPOSE: To attain the maximum working efficiency of a working machine by enabling the machine to exhibit its maximum effective tractive force by an automatic control system for load in which the acceleration in the moving direction of wheel is detected, the speed of the wheel at which its effective tractive force becomes maximum is obtained, and a working machine is driven so as to make the actual speed of wheel an optimum one.
CONSTITUTION: The signal of acceleration from an acceleration detector 30 is sent to a memory device 40, whereupon on the basis of characteristic curves representing correlation between the stored acceleration and target wheel speed, a target wheel speed corresponding to the acceleration is outputted. A working machine position detector 45 detects the position of the working machine which corresponds to the wheel, outputs corresponding position signal, and corrects the target wheel speed. Then, the deviation between the corrected wheel speed and the present wheel speed from the wheel speed detector 45 is obtained. A compensatory amplifier circuit 41 compensatorily amplifies the deviation, drives an actuator 42 according to the deviation, and controls the vertical motion of the working machine 15.
