    • An elongated shuttle car is provided having a set of undriven rail wheels and a set of driven road wheels. The rail wheels are movable between a lowered position wherein they support the shuttle car and a raised position wherein the shuttle car is supported from the road drive wheels. The road drive wheels are independently driven by fluid drive motors, one of which is associated with each road wheel. The road wheels are disposed so as to permit movement of the shuttle car generally perpendicular to its longitudinal axis which is aligned with the rail bed. Hydraulic cylinders or jacks are utilized for raising and lowering the undriven rail wheels which are normally formed of steel. The rail wheels are supported in movable truck assemblies. The movable truck assemblies have an axle permanently attached thereto and a pair of rail wheels are attached to the ends of the fixed axle.
    • 提供了一种细长的梭车,其具有一组未驱动的轨道车轮和一组驱动的车轮。 轨道轮可以在它们支撑梭车的下降位置和升降位置之间移动,其中梭车从道路驱动轮支撑。 道路驱动轮独立地由流体驱动马达驱动,其中一个与每个车轮相关联。 路轮被布置成允许梭车大致垂直于其与轨道床对准的纵向轴线的运动。 液压缸或千斤顶用于升高和降低通常由钢形成的未驱动的轨道车轮。 轨道轮支撑在可移动的卡车组件中。 可移动的卡车组件具有永久地附接到其上的轴,并且一对轨道轮连接到固定轴的端部。
