Technical Field

The invention relates to the technical field of railway maintenance, in particular to a device for railway construction.

Background

In the railway maintenance and rail replacement construction, the transfer of the steel rail is an important work content. In some construction projects, for example, mines, tunnels, bridges and the like, large-scale loaders cannot transport the steel rails to a construction site or can only unload the steel rails at a remote position due to topography, so that the steel rails need to be transported to an accurate position. In the prior art, most of the steel rails are transported by using simple appliances and tools, so that more construction personnel are needed, and the labor intensity is high. Therefore, the rail is transported according to local conditions by using site conditions, so that the method is an effective way for saving labor and improving construction efficiency.
