WIPO Patent Application WO/2022/215413
Kind Code:
A1
Abstract:
Provided is a work machine capable of loading a load onto a fixed point of an object to be loaded therewith. The work machine has a controller that causes a boom (31), an arm (32), and a bucket (33) to be driven on the basis of a target loading point (P) set above a loading platform (56), to automatically perform an operation of releasing earth and sand held in the bucket (33). The controller rotates the bucket (33) so as to make an opening surface of the bucket (33) vertical at the target loading point (P), and then drives the boom (31), the arm (32), and the bucket (33) so as to make the opening surface of the bucket (33) face downward while maintaining a position (T) relative to the machine body of the tip end of the bucket (33) in the front-rear direction.
