● Side wall semi-trailer series

The semi-trailer with a sash-type semi-trailer cargo part is a slab structure. It is widely used in medium and long-distance transportation of medium and heavy-duty and bulk cargo. It has strong applicability and has become the first choice for medium and long-distance freight vehicles.
1. The whole body of the vehicle is made of high-quality steel, advanced technology and strict production. The structure of the whole vehicle is reasonable, the performance is reliable, the operation is simple, and the appearance is beautiful.
2. The series of semi-trailer frames are all beam-type structures, and the longitudinal beams are straight or gooseneck. The web height is welded from 400mm to 550mm manganese plate, the longitudinal beam is automatically buried and welded, the frame is shot peened, the beam is inserted into the stringer and welded.

3. The suspension adopts non-independent steel plate stamping rigid suspension, which is made up of series leaf springs and suspension bearings; the structure is reasonable, with strong rigidity and strength, used to support the load to slow down the impact.

● Flat-bed semi-trailer series

The flat-panel semi-trailer has no fence on the vehicle, and is widely used for medium and long-distance freight transportation.
1. The flat-type semi-trail type walking structure uses high-strength international steel material; the whole vehicle has light weight and guarantees its resistance to twisting, shock and bounce, and meets different road carrying capacity.
2. The series of semi-trailer frames are of the beam-type structure, and the longitudinal beams are of straight or gooseneck type. The web height is from 400mm to 550mm, the longitudinal beam is welded by automatic submerged arc welding, the frame is shot peened, the beam is inserted into the stringer and welded.
3. The series type dry plate spring and suspension support are composed of reasonable structure, strong rigidity and strength, and are used to support load buffering.

● Low bed semi-trailer series

Low-profile semi-trailer goods are also widely used, suitable for a variety of mechanical equipment, large objects, highway construction equipment, large-scale tanks, power station equipment, various steel transportation.
1. The series of low-profile semi-trailers have flat, concave beam and tire exposed structures, and the longitudinal beams are straight or gooseneck. The frame of the frame is stepped, the cross section of the longitudinal beam is I-shaped, and has the characteristics of high rigidity and high strength.
2. The main plane of the cargo platform of the frame is low, which ensures the smoothness of transportation and is suitable for carrying all kinds of construction machinery, large equipment and steel.
3. Three-axis balanced type, double-shaft balanced type or rigid suspension is adopted, and a mass balance block is arranged between the front and rear leaf springs to change the deflection of the front and rear leaf springs to equalize the force of the front and rear axles;
4. Low-profile semi-trailer series products are suitable for a variety of mechanical equipment, large-scale objects, highway construction equipment, large-scale tanks, power station equipment, all kinds of transportation, wide-ranging, efficient and fast. The vehicle adopts advanced computer-aided design software, which is optimized for flexible design. The frame bearing surface is designed according to user requirements to meet the transportation of various special cargoes.

● Fence semi-trailer series

The semi-trailer with a fence structure is used for the warehouse-mounted semi-trailer cargo parts. Mainly used for the transportation of agricultural and sideline products and other light foam goods.
1. The design process of the model and fence structure combines with the user's cargo category, reasonable design, fully compensates the weight of the car when the load is satisfied, the structure is simple and applicable, the disassembly is convenient, and the investment cost is reduced for the user to create more profit value.
2. Frame: The space frame structure is formed by welding the longitudinal beam and the integral penetrating beam. It can balance the strength, rigidity and toughness of the frame, and has strong bearing capacity without permanent deformation.
3. The series of warehouse-type semi-trailers are all beam-type structures, and the longitudinal beams are straight or gooseneck. The web height is from 400 to 500, the longitudinal beam is welded by automatic submerged arc welding, the frame is shot blasting, the beam is inserted into the stringer and welded.
4. Suspension system: It adopts a new suspension system with high strength and strong impact resistance; the load balance of each shaft is balanced, and the system tie rod angle is rationally designed to reduce the frictional slip distance between the tire and the ground during the frequent jolting process. It can effectively reduce the tire wear, and at the same time, the adjustable lever can adjust the wheelbase, effectively avoiding the phenomenon of the tire's partial wear and the wheel.
