The invention discloses a rail carrier comprising a frame, a handle, electric jacks and bearing tables. The frame is a U-shaped frame formed by sequentially connecting a first transverse supporting strip, a second transverse supporting strip and a third transverse supporting strip end to end. The lower end of the handle is installed on the frame, a plurality of universal wheels are installed at the bottom of the frame, the two electric jacks are installed on the first supporting strip and the third supporting strip respectively, and the two bearing tables are installed on the two electric jacks respectively. According to the rail carrier, the U-shaped frame is adopted and can be inserted into the gap between sleepers from the side face of a rail and located below a steel rail. And the electric jacks are adopted as power mechanisms for lifting and lowering the steel rail; the operation is easy, time and labor are saved, and great convenience and high efficiency are achieved; movement inany direction can be achieved through the universal wheels; and the steel rail of the rail can be conveniently carried according to actual construction needs of tunnels and the like.
本发明公开了一种轨道搬运车，包括车架、拉手、电动式千斤顶和承载台，车架是由横向的第一支撑条、横向的第二支撑条和横向的第三支撑条依次首尾连接形成的“U”形架，拉手的下端安装于车架上，车架的底部安装有多个万向轮，两个电动式千斤顶分别安装于第一支撑条和第三支撑条上，两个承载台分别安装于两个电动式千斤顶上。本发明所述轨道搬运车通过采用“U”形车架，能够从轨道的侧面插入枕木之间的缝隙并位于钢轨的下方，并采用电动式千斤顶作为对钢轨进行托举和下放的动力机构，操作简单、省时省力、便捷高效，而且采用万向轮能够实现任意方向的移动，便于根据隧道等实际施工需要搬运轨道的钢轨。
