Semi trailer is a trailer whose axle is placed behind the center of gravity of the vehicle. It is equipped with a coupling device that transfers horizontal and vertical forces to the trailer. It has no driving power or force itself and needs to be connected via kingpin with a tractor to accomplish transportation of goods.
Compared with full trailers, semi trailers are mainly used for long-distance cargo transportation. They can be categorized furthermore. Different types of semi trailers are suitable for different goods. For example, dump semi-trailer is suitable for the transportation of bulk and scattered goods such as coal, ore and construction materials; flatbed and lowbed semi-trailer is suitable for the transportation of vehicles, machines and other heavy-duty goods; cargo fence semi-trailer is mainly used for the transportation of agricultural goods, sideline products, and other light bubble goods; tank semi-trailer is mainly used for the transportation of liquids, bulk materials, and bulk cement; van box semi-trailer can be used for hauling household appliances, light textile goods, and transportation of building materials.
What are the components of a semi-trailer? Generally speaking, structurally semi-trailer can be divided into frame, trailer body, kingpin, suspension system, traveling mechanism, electrical system, landing gear, protective device and trailer accessories.
Frame is the main structure for loading goods. It’s composed of girder, welded I-beam, supporting beam, connecting beam, side beam, lock head, kingpin connecting device, panel, etc.
Trailer body refers to the side wall, front board, etc. It’s the auxiliaries to frame used to load goods.
Kingpin is an important component connecting the semi-trailer and the tractor bearing the traction force to drive the trailer forward.
Suspension system is a device used to connect the frame and axle. It is mainly used to support the load and reduce the impact of vehicle and cargo dynamic load. It can generally be divided into steel plate suspension, single point suspension, air suspension, and rigid suspension. These different types of suspension systems vary in performance, and therefore should be selected according to the purpose of the trailer.
The traveling mechanism mainly refers to the axle system, rim and tire. Its main function is to bear weight, maintain the trailer’s movement, and support and distribute the load between the frame and wheels. At present, some of the Chinese brands that make the best quality axles are BPW, Fuhua, Darong, and York. They are very popular due to their reliable quality.
The electrical system consists of cables, gas circuits, and lamps. It is mainly used for lighting, braking, and safety warning.
Landing gear is the supporting device is used to support the trailer when the semi-trailer is uncoupled from the truck head.
Protective devices can generally be divided into side bumper and rear bumper.
Tool box, spare wheel carrier, plug-in, and other small accessories.
Semi-trailers have very good comprehensive economic benefits, which can improve the transport efficiency by 30-50% and reduce the transport cost by 30-40%. They have played an important role in the transportation industry.
Tank trailers are tank-shaped transport vehicles used to transport various liquids, liquefied gases and powdered goods, including gasoline, crude oil, various viscous oils, vegetable oils, liquid ammonia, alcohol, water, various Acid-base liquid, cement lead oxide powder, etc. Tankers play an important role in transportation, accounting for about 18% of the total number of trucks.
Tankers can be divided into two categories: railway transport tankers and road transport tankers. We have accumulated rich experience, and our products have won wide recognition from customers for their excellent craftsmanship and reliable quality.

Heavy Duty Dump Trailer is also known as Dump Truck, Dump Truck Trailer, Side Dump Truck, Dump Truck Semi Trailer, Scrap Dump Trailer.
In civil engineering, end discharge trailers are often used in conjunction with excavators, loaders, belt conveyors and other construction machinery. The dump trailer compartment adopts rear unloading and side unloading self-unloading methods, which improves the efficiency of bulk cargo transportation by the loader. Dump trailers used to sell carriages are tilted at an angle, so the cargo in the carriages is unloaded. The power of the dump truck trailer engine is used to complete the dump mechanism.
The dump truck uses TITAN axles with 16-ton brake pads. Other factories typically use 13-ton axles. We have more than 15 years of production experience on TITAN axles, which have better performance in terms of load capacity and braking performance. These make us the top heavy duty dump trailer manufacturer and supplier in China.
The hydraulic dumper trailers sold can be customized in different tonnages from 15 tons to 80 tons, 80 tons to 120 tons, 120 tons, 180 tons according to different needs. As well as different types: standard, U-shaped back flip, flatbed container dump semi-trailer, skeleton dump trailer semi-trailer, side dump semi-trailer.
Vehicle Master is top Gooseneck Lowboy semi trailer manufacturer and supplier from china.
The 11m, 13m, and 13.75m three-axle low gooseneck flatbed semi-trailer has no fences in the on-board part. The gooseneck semi-trailer and flatbed trailer are widely used, mainly used for medium and long-distance freight transportation. The frame of the series semi-trailer is a through-beam structure, and the longitudinal beam adopts a straight live gooseneck type. The height of the web is from 500mm to 550mm, the longitudinal beam is welded by automatic submerged arc welding, the frame is treated by shot peening, and the cross beam penetrates the longitudinal beam and is welded as a whole. It is composed of a series dry leaf spring and a suspension bearing, with a reasonable structure, strong rigidity and strength, and is used to support the load and buffer the shock. Low-bed semi-trailers are usually used to transport heavy vehicles (such as tractors, buses, special vehicles, etc.), rail vehicles, mining machines, forestry machines, agricultural machines (such as excavators, bulldozers, loaders, pavers, cranes, etc.) and other heavy-duty goods, the middle section is the cargo platform (the lower part of the frame), and the rear end is the wheel frame (including wheels). When loading mechanical equipment on a low-bed semi-trailer, the mechanical equipment is usually loaded from the rear end of the semi-trailer, that is, the mechanical equipment is moved from the rear wheel frame or the wheels are removed, and then the mechanical equipment is fixed on the semi-trailer. superior. The walking structure of the low-plate semi-trailer is made of high-strength steel, and the weight of the whole vehicle is light, and its anti-torsion, earthquake resistance, and anti-bump ability are guaranteed to meet different road bearing capacities. The gooseneck lowboy semi-trailer and the flat-bed trailer are used for pulling large excavators. 400 hp towing
