  • Patent number: 4304187
    Abstract: A monorail system having a rail surface that is provided for small vehicles traversing an incline or slippery areas, with the surface having a plurality of spaced recesses positioned in those areas to form gripping edges for the drive wheels of the vehicles. The recesses may be of a variety of shapes and positioned in different ways to provide the proper grip. The recesses may be mechanically punched into a separate elongated flat bed riveted in appropriate locations to the rail. The punching may be done in such a way so as to form raised ramp-like edges adjacent the recesses to help with the gripping action. The ramp faces face downwardly in inclined areas. The drive wheels of cooperating vehicles may have elastic treads to help with the gripping action.
