The pier in water occupies the river course, causes navigation and flood control problems, is difficult in construction and construction, high in construction cost, complex in construction and approval procedures, and the connection curve railway still occupies precious shoreline resources. The railway arrangement has the defect that railway connection curve bridges need to be designed at both ends of the wharf trestle. According to the current railway design standard, a 90-degree railway curve needs a radius of 200-300 m. Two bridges connected with curves tend to occupy 400-600 m river channels and precious quay line resources.

The power source for vehicle transmission on the existing trestle is mainly locomotive traction and tippler traction. The locomotive traction adopts an internal combustion locomotive as traction power, the power is abundant, but the pollution is large, the alignment is not accurate, the locomotive cannot be turned, and the occupied area of the locomotive puller is very large. The continuous conveying can not be realized by adopting locomotive traction or car puller traction, so that a new automatic conveying system for the vehicles of the combined transport terminal for molten iron is needed to be provided.
