What's Drawbar Trailer.

Drawbar TrailerDrawbar flat trailer generally uses inflatable solid tire, low surface height, large load. There is no danger of tire breakage or puncture. Safe, simple and durable. It has no power of its own and needs a tractor or forklift to tow it. Usually one or more flat trailers and a forklift or tractor form a train to carry goods flat or move large equipment. Widely used in airports, ports, railway stations, factories and large warehouses. Greatly improve the efficiency of goods transfer and translation. Reduce the cost of forklift and manpower.

The drawbar trailer is generally composed of frame, body, traction device, steering device, suspension, walking system, braking system, signal system and so on. The frame is mainly composed of main beam, beam, supporting beam and side beam. The upper wing surfaces of the straight beam rail are straight. Its advantages lie in the flat bottom of the trailer cargo platform, simple manufacturing process, generally higher clearance from the ground, good longitudinal passage.

Rail-plate compartment is generally made of thin steel plate, the longitudinal concave edge plate is stamped on the rail-plate of the compartment, and the transverse rib is welded to increase the rigidity of the compartment and reduce the quality of the compartment;The floor of the carriage is generally made of wood and covered with thin steel plates, or the floor of mixed iron and wood structure.

The frame is usually made of 16Mn steel plate, which is pressed into profile and welded or welded with willow. The longitudinal and transverse beams of the frame are mostly grooved interface structure, and the two longitudinal beams are equally wide before and after, so that the frame has better bending resistance.

Classification of drawbar trailer:
1.Flatbed drawbar trailer - drawbar trailer with flat floor structure and no pallet at the loading part.

2.Container drawbar trailer - a drawbar trailer with a frame structure and no floor for carrying cargo, specially for transporting containerized compartments.

3.Dump drawbar trailer - drawbar trailer with automatic tipping device for loading part.

4.Tank drawbar trailer - drawbar trailer with closed tank structure for loading parts.

The difference between drawbar trailer and semi trailer:
Unlike a semi-trailer, a semi-trailer is a trailer where the axle is placed behind the center of gravity of the vehicle (when the vehicle is evenly loaded) and equipped with coupling devices that transfer horizontal or vertical force to the tractor! 

The general trailer has two shafts, and the semi-trailer has one shaft. Semi-trailer refers to a vehicle that has no power itself and carries the load jointly with the main vehicle and relies on the main vehicle to drive.
