ABSTRACT:
A gripping claw for a backhoe, breaker, or similar device is secured to the end of a boom in a pivotal manner. Attachment is achieved through a pair of plates joined together facing each other, with the claw pivotally mounted at one end in the space between the plates. A piston and cylinder, also mounted in the space between the plates, joins the plates to a second location on the claw, both being pivot connections, so that extension and retraction of the piston causes the claw to pivot between open and closed positions. To install the attachment on a boom-mounted tool, the tool is detached from the boom, and the attachment inserted in its place, with the tool in turn secured to the attachment. The attachment thus serves as an extension, and is readily installed and removed on site.
