  • Publication number: 20110316330
    Abstract: A continuous track with replaceable components permits a light weight tracked vehicle to benefit from the cost savings associated with repairable tracks. Each repairable track includes two parallel continuous belts, each belt includes embedded plates to reinforce the belts and distribute the load applied by the vehicle drive train and the load applied by the shoe to the belts. Each shoe assembly engages the parallel belts and includes a track guide, a shoe plate and a shoe. The number, separation and orientation of the shoe assemblies are preset for a set of parallel belts, however shoe assemblies and the elements of the shoe assemblies may be used for many different belt sets. Any suitable fasteners may be used to secure each shoe assembly to the belts.

  • Patent number: 7641293
    Abstract: An offset track forms a pattern perpendicular to the centerline of the track which enables tracks to be formed with even or odd number of metal inserts and thus accommodate virtually any tracked vehicle. The offset track uses variations in body thickness and lug width to provide a high performance offset track with improved ride, minimum vibration and longer wear. Use of full size and mini-inserts in a single track minimizes the weight and further enhances the performance of an offset track.

  • Patent number: 6478389
    Abstract: Low ground pressure tire chains for skid-steer loaders and other construction machinery. A track (12) for parallel drive wheeled vehicles (10) having spaced apart pairs of wheels (14,16) assembled with a plurality of base units (24) pivotally interconnected in series by opposing links (26), each base unit comprising a pair of opposing side supports (32) with a wedge portion (36) extending towards the opposing side support to wedgingly receive a portion of a tire in a gap between the opposing side support's. A pair of spaced-apart transverse cross members (34) extending between the side supports and define cavities (50) between a leading edge and the wedge portion for receiving fasteners to secure a bottom plate (52) to the base unit. The assembled track mounts around the tires of the loader to provide traction and floatation of the loader during operation in mud or sand.
