In the early stage of container transportation development, ordinary trucks were mostly used for transportation because of the small carrying capacity and small quantity of containers. Since the 1960s, with the rapid development of container transportation, countries have developed special vehicles to transport containers. The size of the loading part of the container trailer shall be determined according to the size of the standard container, and a twist lock device for fixing the container shall be set at the position corresponding to the four corners of the bottom of the container. Special transport trailer for carrying containers. The four corners of the loading part are provided with a twist lock device for fixing the container. Semi hanging type, full hanging type and double hanging type are usually adopted, and semi hanging type is more. Semi hanging type can be divided into flat type and skeleton type. The former has flat pallet, which can also be used to transport Ordinary long and long goods; The latter has no pallet, and the container is installed on the chassis frame and fixed by the twist lock device as the strength member of the semi-trailer.

Tank semi trailer
Tank semi-trailer is a semi-trailer with tank structure at the loading part. It is mainly used to transport liquids, bulk materials and bulk cement. 1. Tank truck series is divided into oil tank truck, concrete mixer, powder material and bulk cement truck, water supply truck, etc. 2. The tank body is manufactured through three-dimensional design and advanced processing technology. The chassis is made of various manufacturers' specialized chassis, with advanced technology and reliable performance. A truck with canned containers. Advantages: high loading, unloading and transportation efficiency. Ensure the quality of goods. Conducive to transportation safety. Reduce labor intensity and improve loading and unloading conditions. Save packaging materials and labor. Reduce transportation costs. Liquid tank truck: transport fuel, lubricating oil, acid, alkali, water, food and beverage, etc Powder tank truck: transport and load cement, flour, stone powder, etc. Gas tanker: Transport nitrogen, argon, petroleum gas, etc. particle tanker: transport grain, beans, granular plastics and other granular articles. Other special tankers: concrete mixer, sprinkler, sweeper, etc. Tank cars are divided into low-pressure tank cars (the internal pressure borne by the tank body is generally less than 0.09mpa. It is mainly filled with water and light fuel oil), medium-pressure tank cars (the internal pressure borne by the tank body is generally 0.147-0.294mpa. It is mainly filled with caustic soda, asphalt, etc.) and high-pressure tank cars (the internal pressure borne by the tank body is generally 1.177-3.532mpa).

Van semi-trailer
Van semi-trailer series products are used for the transportation of household appliances, light textile goods, coal, gravel and other building materials as well as drawing and plate goods. The car body is made of high-strength cold rolled corrugated steel plate with no skeleton structure, the center is everywhere, various choices, large loading space, reasonable distribution in the box body, X-shaped pull brace, which has the characteristics of multi pull, heavy load and light weight. The car top has closed type, push open type, open type, open tarpaulin pole type, etc., which is easy to operate and meets the diversified and personalized requirements of users. The van transport semi-trailer adopts the closed side guard rail design, which can effectively reduce the lateral risk and energy consumption when the vehicle is running at high speed. The rear protection design has reasonable trolley accessories for convenient operation. It is refitted or manufactured separately on the chassis of the van. According to the different carriages, it can be divided into passenger van type and carriage type. The passenger compartment and cab are generally integrated structures, such as ambulances, accommodation vehicles, environmental testing vehicles, dining vehicles, TV broadcasting vehicles, etc. Carriage type carriage and cab are generally split structures, such as van type less than carload transport vehicle, refrigeration and insulation vehicle, etc. The specific structural form of the carriage varies according to its function. The compartment of the refrigerated and insulated vehicle not only has the function of general compartment, but also has the function of heat insulation and heat preservation; The top cover of the convertible top carriage can be lifted vertically to change the volume of the carriage and meet the loading and unloading requirements of different goods; The wing open carriage is convenient for cargo loading and unloading and improves loading and unloading efficiency. Series van is divided into box type fortune semi-trailer and class II chassis modified van. The vehicle body is made of high-quality steel, advanced technology and strict production process. The vehicle has reasonable structure, reliable performance, simple operation and beautiful appearance. The accessories are from well-known manufacturers at home and abroad, and are purchased, inspected and used in strict accordance with the requirements of quality system documents, so as to ensure the good performance of the whole vehicle.
