While rotatably connected by a rotating shaft,
The outer ends of the two bucket main bodies and the hanging part are connected by a rotatable link, and the hanging part and the rotating shaft are connected to each other by a connecting means so as to be able to come into contact with each other. In a grab bucket which is configured to open and close the bucket main body by coming into contact with and separating from the bucket, one end of a movable plate having a shape along the bottom frame is mounted inside the bottom frame of both the bucket main bodies and near the excavation claw. While being movably attached, the other end of the movable plate attached to each bucket main body is connected to the opposing bucket main body by a flexible member, respectively.
When the hanging part and the rotating shaft are separated and the bucket main body is opened, the movable plate is rotated by the flexible member so as to be separated from the bottom frame. Grab bucket.
