[0002] With the transformation of my country's economic development mode and the optimization and upgrading of industrial structure, the cargo throughput of ports has gradually increased. In recent years, the number and types of steel arriving at the port have also increased. The increase in these steels will inevitably lead to the increase and use of steel transshipment operations in the port. It is inconvenient to use conventional 12-meter transport vehicles to transship steel. Conventional transport vehicles have low loads, low transportation efficiency, high purchase costs, and are easy to damage the vehicle, shortening the service life of the vehicle, resulting in increased vehicle transshipment costs and increased maintenance rates. Different goods have different requirements for vehicles. For example, iron pipes and round steel profiles are generally longer products of about 16 meters. However, for rolled steel profiles, which are small in size but heavy in weight, this type of profile has high requirements for the strength of the vehicle, but not high requirements for the length of the vehicle. It is difficult to find a vehicle that meets the above working conditions on the market. Therefore, according to the diversity and particularity of the types of steel transshipped at the port, this simple, practical, economical, high-load-bearing 16-meter trailer is specially designed for operation.

[0027] By adopting the wheel layout and traction structure of this structure, the strength load of the whole vehicle can reach 60 tons, which can ensure the completion of work requirements.

[0028] Except for the wheel train 5, the whole structure is made of Q355B metal. To ensure its strength and load requirements, the vehicle body 2 structure consists of three longitudinal beams, two longitudinal secondary beams, and multiple transverse vertical ribs, which are evenly arranged from the end to the back. A total of 8 ingot beam sockets 3 are symmetrically equipped on both sides of the vehicle. The front end of the carriage is 920mm high, and the height of the plane on the carriage at the center of the wheel train 5 is 1000mm from the ground. The distance between the center of the wheel train 5 and the tail of the carriage is 3300mm, and the gooseneck socket is located in the middle of the front end of the carriage and the lower part of the panel.
