Having no coaming in its loading part, the low bed semi-trailer is mainly applicable to the medium and long-distance transport. Having the web plate's height ranging from 400mm to 550mm, our low loader semi-trailer has the frame of cross beam structure and the stringer of straight type or gooseneck type. We adopt the automatic submerged arc welding to the stringer and shot blasting to the frame. Penetrated through the stringers, the beams are welded with the stringers as a whole.

Formed by the dry plate clutch spring of tandem type and the suspended pedestal, the low bed semi-trailer's reasonable composite structure features strong rigidity and strength, which can effectively support the loading and slow down the shock.

Having low center of gravity, stability and safety, our lowboy semi-trailer is ideal for the transport of heavy-duty cars, such as tractor, coach, special vehicle, etc.; railway vehicle; mining machinery; forestry machinery; agricultural machinery and equipment, such as excavators, bulldozers, loaders, pavers, cranes, etc.; and other heavy cargos.

Features of Low Bed Semi-Trailer
1. Sophisticated Technology
The main parts of our low bed trailer are processed with advanced equipment. The stringers are welded by the imported German automatic submerged arc welding machine. The axles are assembled by the specific assembly machine and the wheelbase is accurately measured by the rangefinder. We adopt the electrical testbed to debug the electric circuit of our low bed semi-trailer. Treated with shot blasting, the parts and components have increased adhesive force to the paint.

2. Powerful Frame
Adopting the welded stringers made of 16Mn high tensile structural steel, this low bed semi-trailer has the space frame structure installed and welded by penetrated beams. Featuring excellent strength, stiffness and tenacity, this reasonable structure can support heavy payload without deformation.

3. Superior Axle
The axle can also support and balance the heavy payload without deformation. Selectable from the famous foreign brands and well-known domestic brands, our low bed semi-trailer's ABS anti-lock braking system can effectively reduce the braking distance. It can help to guarantee your safe driving by avoiding the sideslip, drift and other unexpected accidents caused by the locked wheel in the condition of emergency brake.

4. Excellent Suspension System
We have unique suspension system featuring high strength and excellent shock resistance. Each of our low bed semi-trailer's axles can support and balance the payload. The angle of systematic pull rod is reasonably designed to reduce the distance of sliding caused by the friction between tires and ground, which can protect the tire. Our low bed semi-trailer's adjustable pull rod and adjustable wheelbase can effectively avoid the eccentric wear and lug wear.

5. Reliable Braking System
We adopt safe and reliable dual-circuit air braking system and high-performance relay valve to our low bed semi-trailer. The storage pump also has the parking braking function.

6. Various Gooseneck Structures
Our low bed semi-trailer has all kinds of gooseneck structures with lower loading surface, which can meet various requirements of different goods' transports.
