ABSTRACT:
Pilot-channel apparatus is provided for guiding movements of runnered vehicles, equipment fitted with skid runners and containers with runners for three-dimensional displacements such as loading and transport on/off wheeled trailers and for two-dimensional displacements such as movements within a planar storage area. Unitary and multiple pilot channels incorporate characteristic forms with specified features for safe, reliable engagement with known runner profiles to control lateral and transverse powered movements, especially loading of snowmobiles onto a trailer. Pilot- channel apparatus is supplied in the form of formed shapes and bands of length up to approx. 10 meters which allows customized placement, mounting and spacing of specific pairs of fixed or moveable channels. Specific two- and three- dimensional pilot-channel arrays and kits with specific shapes of pilot channels are indicated for owner- installation on existing snowmobile trailers. Special all-purpose channel arrays adapted to engage a broad range of known runner profiles on snowmobiles can be factory installed on new trailer frames with attendant savings in trailer cost and weight.
