The heavy hydraulic combination semitrailer presented in this article consists of a gooseneck neck and a cargo table. The gooseneck neck is equipped with a traction pin, a gooseneck steering device and a gooseneck lifting device. The platform is modular in design with front and rear modules Mechanical steering and hydraulic suspension devices; intermediate module depending on the cargo needs can be flat beam or concave beam. The cargo platform can be raised and lowered is one of the main characteristics of the model, and the mechanical linkage steering mechanism used to make the vehicle to complete follow-up steering and steering control, which greatly improves the reliability of transport, mobility and economy.
