本欧洲标准描述了与使用小型货车的铁路运输的半挂车相关的铁路具体要求。为此，半挂车适用于起重机的搬运。他们由龙门起重机或移动转运设备由抓斗口袋使用抓斗并提升到口袋货车。半挂车的轮子位于货车的凹下的装载区域（口袋）上，前端带有千斤顶的五轮盘。主销被锁在千斤顶中，负责半挂车在各个方向的固定，因此也可以承受相关的力量

This European Standard describes the railway-specific requirements relating to semi-trailers which are transported by rail with pocket wagons. For this, the semi-trailers is meant to be suitable for handling by crane. They are handled by gantry cranes or mobile transhipment equipment by the grappler pockets using grabs and lifted into the pocket wagons. The semi-trailers rests with their wheels on the sunken loading area (pocket) of the wagon and at the front with the fifth-wheel plate on the jack. The king pin is locked in the jack and is responsible for the fixing of the semi-trailer in all directions and hence also for withstanding the relevant forces.
