摘要： There is provided a clamping apparatus for clamping railroad cars into a rotary dumper capable of inverting cars to discharge the contents. The clamp is characterized in having a jaw member pivotally mounted on one end of an extensible arm. Stationary guide means are provided for coaction with the jaw to guide it along a predetermined path. Means are also provided coacting between the support and the jaw member for tilting the jaw member so that it clears the maximum composite envelope of locomotive profiles within the opening provided in the adjacent end ring of the rotary railroad car dumper.
摘要翻译：提供了一种用于将铁路车辆夹紧到能够倒车以排出内容物的旋转自卸车的夹紧装置。夹具的特征在于具有可枢转地安装在可伸长臂的一端上的钳口构件。提供固定引导装置用于与钳口协调以沿预定路径引导它。还提供了在支撑件和钳口构件之间共同作用的装置，用于使夹钳构件倾斜，使得其清除设置在旋转式铁路车辆倾倒器的相邻端环中的开口内的机车轮廓的最大复合包络线。

摘要： There is provided a railroad car spotting and wheel locking assembly for coaction between a pair of railroad car wheels and the rail on which the wheels are supported. The apparatus is characterized by a housing and a pair of spaced oppositely acting wheel engaging chock arms pivotally mounted in the housing for movement in a horizontal plane. Means such as hydraulic means are provided for moving the chock arms into and out of wheel locking engagement. An advantage of the present apparatus is that it can be used to effect limited movement of the railroad car or a train of railroad cars to more accurately spot the car and thus cars attached thereto for car unloading operation.
摘要翻译：提供了一种用于在一对铁路车轮与支撑车轮的轨道之间进行协调的铁路车辆检测和车轮锁定组件。该装置的特征在于壳体和一对间隔开的相互作用的轮接合轴承臂，其可枢转地安装在壳体中以在水平面中移动。提供诸如液压装置的装置用于将阻塞臂移入和移出轮锁定接合。本发明的优点在于，它可以用于实现铁路车辆或铁路车辆的有限的移动，以更准确地将汽车以及因此连接到其上的汽车点亮以进行汽车卸载操作。
