ABSTRACT:
An endless self-laying tread or track such as used on self-propelled mining machines and the like, the tread or track being comprised of a plurality of articulated crawler pads configured so as not only to effect good ground engagement but also to assist in preventing the tread or track from becoming clogged. A plurality of the crawler pads are arranged in interdigitated relationship and connected by elongated pins. As so connected open ended spaces are provided at either side of the tread for engagement by the teeth of a driving sprocket. By this arrangement such teeth may be wider and thicker. The space occupied by such a sprocket tooth, being open ended, greatly facilitates the dispersement of any accumulated packing between the tooth and the crawler pads in a sideways direction. One or more pins or pintles are used to connect each adjacent pair of interdigitated pads. The ends of the interdigitated portions of the individual crawler pads may be squared off so as to positively engage, and then push therefrom, the surface material on which the tread runs. By arranging the tread so that it may be drivingly engaged by sprocket teeth operating at the open ends of the crawler pads, the interior spaces usually required to receive the sprocket teeth are no longer needed and a single, larger diameter pintle can be used while at the same time providing additional crawler pad bulk about the pintle whereby to beef-up the entire tread structure. The crawler pads may utilize improved grousers or ground penetrating ribs.
