ABSTRACT:
A crane tool attachment is provided for removable mounting to the arm of a backhoe from which the bucket has been removed. A frame is fittable on the backhoe arm at its outer end and is fastened thereto. A sleeve is mounted to the frame so as to be directed substantially parallel to the backhoe arm, and a boom is insertable through and moveable along the sleeve. The inner end of the boom is connected to a hydraulic cylinder disposed along the backhoe arm normally for pivoting the bucket when in place, for moving the boom along the sleeve. A hydraulically-powered winch with a cable is mounted to the sleeve and is connected to a source of hydraulic fluid under pressure within the backhoe machine. A pulley is mounted for rotation at the outer end of the boom for passage of the cable therearound, and a hook is connectable to the free end of the cable.
