摘要： The invention provides a method of replacing the wheels of a railroad car while the railroad car is at rest on rail tracks. Most advantageously, the rail car need not be uncoupled from adjacent cars. The method also has the advantage that rail cars are jacked at the coupler thereby making the method applicable to all types of cars including grain and oil cars which cannot be jacked in their midsections. The method comprises the steps of: releasing the wheel to be replaced from the rail car; transverse insertion of a jack between the rails and the underside of the coupler; actuating the jack to lift the rail car supported upon the underside of the coupler; removing the wheel to be replaced; replacing the wheel; actuating the jack to lower the rail car onto the replaced wheel; securing the replaced wheel to the rail car. The invention also provides a jack for raising and lowering an end of a railroad car having a coupler extending therefrom, the railroad car being at rest on longitudinal rail tracks, the jack being disposed between the rails and the underside of a coupler, the jack comprising: a base supported upon the rails; a cap disposed in parallel above the base; coupler support means for supporting the rail car coupler upon the cap; and lifting means, disposed between the base and cap, for selectively raising and lowering the cap relative to the base between a collapsed position wherein the jack is clear of the rail car to facilitate transverse insertion between the rails and the underside of the coupler, and a maximum lift extended position. Advantageously the coupler support means comprise a travelling table means for shifting the coupler transversely thereby aligning the rail car wheel flanges on the rail head.

摘要翻译： 本发明提供一种在铁路车辆在轨道上静止时更换铁路车辆的车轮的方法。 最有利的是，轨道车不需要从相邻的车辆脱离。 该方法还具有以下优点：轨道车辆被连接在联结器上，从而使该方法适用于包括粮食和汽油车在内的所有类型的汽车，这些汽车不能被夹在其中心部分。 该方法包括以下步骤：从轨道车辆释放待更换的车轮; 在导轨和联接器的下侧之间横向插入千斤顶; 启动千斤顶以提升支撑在联接器下侧的轨道车厢; 拆下要更换的车轮; 更换车轮; 致动千斤顶将轨道车辆降低到更换的车轮上; 将更换的轮固定到轨道车。 本发明还提供了一种用于升高和降低具有从其延伸的耦合器的铁路车辆的端部的千斤顶，铁路车辆在纵向轨道轨道上静止，插座设置在轨道和耦合器的下侧之间，千斤顶包括 ：支撑在轨道上的基座; 在基座上平行设置的帽; 耦合器支撑装置，用于将轨道车联接器支撑在盖上; 以及设置在基座和盖之间的提升装置，用于在收缩位置之间相对于基座选择性地升高和降低盖子，其中千斤顶远离轨道车厢以便于轨道和联接器的下侧之间的横向插入，以及 最大升降机延伸位置。 有利地，联接器支撑装置包括用于横向移动联接器从而将轨道车轮凸缘对准在轨头上的行进台装置。
