A slat-type semi-trailer is a semi-trailer with a fence structure design in the cargo area. The frame is a through-beam structure, and the longitudinal beam is straight or gooseneck. The web height ranges from 400 to 500, the longitudinal beam is welded by automatic submerged arc welding, the frame is shot blasted, and the crossbeam is inserted into the longitudinal beam and welded as a whole.

Slat-type transport semi-trailers are divided into 9-10-11-13 meter long semi-trailers, with two-axle, three-axle and single-axle. With its specific advantages such as large loading capacity, fast transportation, convenient disassembly, wide application and low investment cost, slat-type transport semi-trailers have been rapidly developed and widely used, and have become the main equipment for China's road transportation.

The model and fence structure design process of the slat-type transport semi-trailer are combined with the user's cargo category, and are reasonably designed to fully reduce the weight of the carriage under load conditions. The structure is simple and applicable, and it is easy to disassemble, which reduces investment costs for users and creates more profit value.

Stake trucks are used to transport simple goods, such as vegetables, fruits, clothes, electrical appliances, and other daily necessities. They also play a very important role in power engineering and communication engineering. For small equipment in engineering, they are all transported by stake trucks.
