摘要： A crane control method in which the parcels suspended from a rope is transversely carried by a trolley, the control being performed in an accelerating, a constant velocity travel, and a decelerating period separately, wherein the control is performed during said accelerating and decelerating only by turning on and off a predetermined accelerating and decelerating forces. More particularly, the control is performed by turning on and off the limit current value of the armature current through the motor. The present invention eliminates the necessity for feedback control by which a velocity pattern is followed.
