<p>A multiple tool attachment system is adapted to be attached to demolition equipment. The system includes a universal body attached to the demolition equipment. A series of tools is independently attachable to the universal body. The universal body includes a guide slot extending longitudinally along the universal body. Each tool generally includes a pair of pivotable jaws adapted to be pivotably attached to the universal body with at least one linkage extending from the universal body and attachable to each jaw of the tool. A slide member is received within the guide slot, with each linkage attached to the slide member, and a piston cylinder arrangement is attached to the universal body and coupled to the slide member for moving the slide member and the jaws. The multiple tool attachment system is provided with quick change features and is designed to optimize the cutting characteristics throughout the movement cycle. A tool set such as a grapple may be centrally supported by bridge housings thereby minimizing the stresses across the main pivot pin. Additionally, a tool set such as a grapple may have tine surfaces with wear plates welded directly thereto to minimize wear.</p> |
