ABSTRACT:
A demolition tool for attachment to the boom structure and hydraulic system of a hydraulic excavator having a pair of jaws pivotally connected together as to be mountable on the frame of the tool by a movable pin so that the jaws may be placed with other jaws having other forms of demolition characteristics. The jaws may be a shear for steel or other structural material, including concrete, and the jaws may be a concrete crusher, a rock or coral breaker, a wood shear, a plate shear, or other form of demolition device. Both jaws are swingable and independently swingable, operated by a common manifold supplying hydraulic fluid to the cylinders. The jaws swing through operational arcs and are arranged so that the direction of thrust from the cylinders is tangential to the pin connecting the cylinders to the jaws at a location intermediate the ends of the operational arcs.
