したことを特徴とするパワーシヨベル。[Claims for Utility Model Registration] A power shovel comprising an upper rotating body provided on a lower traveling body, and a front structure provided with a bucket at the tip of the upper rotating body, which is pivotally attached to the upper rotating body. a lower boom pivotably attached to the lower boom; a sub-arm consisting of a first frame pivotally attached to the upper boom and a second frame provided to the first frame via a rotating device; and the sub-arm. an arm pivotally connected to a second frame of the arm; a bucket belt pivotally connected to the arm; the lower boom, the upper boom, and the sub-arm;
The front structure is composed of a plurality of hydraulic cylinders that rotate the arm and the bucket about their respective pivot points, and the minimum turning radius of the arm side is set within the rear end turning radius of the upper rotating structure. The power shovel is characterized in that the direction of the bucket can be changed by rotating the second frame by the rotating device.
