Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a work machine capable of surely locating a swing bracket at a central position by causing an operator to recognize that the swing bracket is located at the central position.

SOLUTION: A work machine comprises: a machine body; a support bracket which is provided in a forward protruding state in the machine body; a swing bracket which is pivoted by the support bracket so as to be horizontally rocked; a boom which is pivoted by the swing bracket so as to be vertically rocked; a swing sensor which detects a position of the swing bracket; and a control device capable of acquiring a detection signal from the swing sensor and controlling a swing operation that is a rocking operation of the swing bracket. The control device includes a swing stop unit which stops the swing operation when the swing bracket is rocked to a central position where the boom is turned in a front direction of the machine body.
