Abstract
PURPOSE: A moving speed of a bucket is applied as an instruction value, both boom rotational speed and arm rotational speed corresponding to the instruction value are calculated, the bucket is controlled in its movement and the movement of the bucket is controlled freely by the operator.
CONSTITUTION: In case of a trench excavation, the change-over switch SW is set to a position of the trench excavation. The arm lever 10 is used for setting a desired value of X-axis moving speed of the bucket edge point D, and the boom lever 11 is used for setting Y-axis moving speed. The bucket lever 12 is used for setting a rotational speed of the bucket 3. When a rotational speed of the boom 1 in respect to the body of the working machine, a rotational speed of the arm 2 in respect to the boom 1 and a rotational speed of the bucket 3 in respect to the arm 2 are applied to each of the feeding flow rate control systems 13, 14 and 15 for the cylinders as the desired value, only the arm lever 10 is operated and the edge angle in respect to the body is kept constant and the bucket 3 is moved in X-axis direction, an operation of only the boom lever 11 causes the edge angle to be kept constant in respect to the body and then the bucket 3 is vertically moved.
