The Hydraulic Bucket Clamp, or thumb, is an attachment for hydraulic excavators that is mounted opposing the excavator bucket and enables the operator to grasp and hold a variety of objects, in the same manner as he would with his hand. This is controlled by utilizing joystick mounted electro hydraulic controls.
