Abstract
PURPOSE: To prevent spillage of earth from a bucket by arranging so that the bucket may be maintained at a fixed elevation angle with the movement of a boom and an arm of a power shovel.
CONSTITUTION: When a bucket 1 is maintained at a fixed elevation angle with a ground through the manual operation of an arm 2 and a boom 3 of a power shovel, an angular velocity 27 of the bucket is sought based on an angular velocity 7 of the arm and an angular velocity 8 of the boom. Then to the angular velocity of bucket, a signal equivalent to a target value of bucket angular velocity is added as a feed forward signal 26 after correcting the effect of a load pressure of a hydraulic cylinder for bucket 22. In addition, a feedback signal (25) for the bucket angular velocity is applied to a bucket angular feedback control system.
