PURPOSE:To raise the workability of a power shovel by a method in which a pair of clamp claws capable of rocking toward horizontal direction are set on a clamp frame on the tip of arm, and a bucket is also detachably attached to the clamp frame. CONSTITUTION:A bucket 1 with clamp claws which are set on the tip of an arm 3 consists of a clamp frame 2 and a bucket 6 detachably attached to the frame 2. A pair of clamp claws 22A and 22B attached to the frame 2 are rocked around pins 31 by an oil-pressure cylinder. A hook 60 coupled with the stay pipe 70 of the bucket 6 and a hook lever 300 coupled with the stopper 80 of the bucket 6 are provided in such a way as to enable the bucket 6 to be freely detached or attached. The latch lever 300 is turned, coupling with the stopper 80 is released to remove the bucket 6, and the grasping operation of materials by the clamp claws 22A and 22B is made more visible. The workability of the power shovel can thus be enhanced.
