Abstract:
A machine for removing, in large pieces, old roofing material in the form of built-up composite from a roof deck and placing the removed roofing material into a cart for disposal, comprising:(a) a wheeled frame; (b) a lower front member attached to the wheeled frame, the lower front member including a blade and a heel which diverges rearwardly therefrom, the blade and the heel defining a structure which opens downwardly, the blade having a chisel-like edge and a generally flat upper surface which extends rearwardly thereof, the chisel-like edge having an upper face, the upper face having a greater upward slope than the flat upper surface, the chisel-like edge, during use, remaining generally fixed in position with respect to the wheeled frame; (c) means, including two power driven wheels, for simultaneously moving the frame and the lower front member forward, so that the chisel-like edge of the front member can be forced between the old roofing material and the roof deck, prying off the roofing material; (d) means for automatically conveying the old roofing material, once it has been pried off, from the roof deck to the cart; and (e) means for independently controlling speed and direction of rotation of each of the power driven wheels, so that the wheeled frame can be moved within a very short turning radius.
