ABSTRACT:
Disclosed is a pivotal movement control device for a boom-equipped working machine provided with a pivotal movement control responsive to the inclined angle of a control lever and a position detector for detecting the moved position of a boom in a lateral direction. The device includes a changeover switch for changing between an automatic mode and a manual mode, an automatic target position stop control for storing a signal from the position detector as a target stop position when the changeover switch is changed from the manual mode to the automatic mode and pivotally moving the boom to the target stop position and stopping it there while reading a positional signal from the position, when the boom is at a position other than the target stop position and the control lever is operated to the side of the target stop position. The device also includes a manual control for controlling the boom according to a signal from the pivotal movement control when the control lever is operated in another manner and when the changeover switch is in the manual mode.
