ABSTRACT:
A gantry truck assembly for rolling on a rail (16) where the rail has a top rail surface (42) and a side rail surface (48). The truck has a wheel (38) for rolling on the top rail surface. A flange (44) extends radially from the wheel and can contact the side rail surface (42). A side roller (56) is rotatably mounted to a lever arm (54) and is biased by a spring (62) to a position closer to the side rail surface than is the wheel flange. When a force greater than a pre-set limit is placed on the roller by the rail, the lever arm can pivot to allow the wheel flange to contact the side rail surface.
