The load of the trailer is fully borne by itself, and it is connected with the locomotive only by hooks. The locomotive does not need to bear the trailer load, but only provides power to help the trailer overcome the frictional resistance of the road. Full trailers are mainly used for transportation in docks, factories, ports and other fields.
Drawbar trailer flatbed trailers are also called "full-trailers, flatbed trailers, flatbed trailers, trailers", generally inflatable solid tires, low board height, large loading capacity. There is no risk of tyre breaking or puncture. Safe, simple and durable. He has no power and needs a tractor or forklift to tow. Usually one or more flatbed semi-trailers and a forklift or tractor form a line of vehicles to carry out the plane transportation of goods or the handling of large equipment. It is widely used in airports, ports, railway stations, factories and large warehouses. Greatly improve the efficiency of goods transfer and translation. Reduce the cost of forklifts and manpower consumption.

There are many types of drawbar trailers, and the basic frame, body, and running system are basically the same as those of trucks. Railcars are generally made of thin steel plates. The rails of the carriages are stamped with longitudinal concave ribs, and transversely welded with ribs to increase the rigidity of the carriages and reduce the quality of the carriages; the floor of the carriages is generally made of wood and covered with thin steel plates. , Or use iron-wood mixed structure floor; the frame is usually made of 16Mn steel plate, pressed into profiles, welded or welded. The longitudinal and transverse beams of the frame mostly adopt a groove-shaped interface structure, and the two longitudinal beams are arranged at the same width before and after, so that the frame has better bending resistance.

A drawbar trailer is generally composed of a frame, a body, a traction device, a steering device, a suspension, a traveling system, a braking system, and a signal system. The upper wing surfaces of the straight beam frame rails are all straight. The advantages are that the bottom plate of the trailer cargo platform is flat, the manufacturing process is simple, the ground clearance is generally high, and the longitudinal passability is good. The heavy-duty flat trailer is in order to meet the requirements of its structure and use. The frame is mainly composed of main beams, cross beams, supporting beams and side beams. The load of the whole vehicle is transmitted to the ground through the support beams, suspensions, wheel axles and wheels between the beams.

The main beam, supporting beam and side beam of the frame are welded parts with box-shaped cross-sections, which have greater torsional rigidity. The beam connecting the main beam extends to both sides and is a variable cross-section I-shaped welded structure with high transverse bending strength. The height of the main beam of the frame is larger, and it extends downwards, so that the frame does not increase the height of the cargo platform. Under the circumstances, the longitudinal bending strength of the frame is improved. A turntable mechanism for installing balance suspensions is arranged under each supporting beam to realize all-wheel steering.
Heavy-duty trailers carry high quality goods and large dimensions. Generally speaking, the strength of the frame should be increased, and the height of the frame should be reduced as much as possible to facilitate the loading, unloading and transportation of the goods. According to the structure of the longitudinal beam, the full trailer frame includes a straight-through frame, a stepped frame and a concave beam frame.
Structure of the drawbar trailer
Different from a semi trailer, a semi trailer is a trailer whose axle is placed behind the center of gravity of the vehicle (when the vehicle is evenly loaded) and is equipped with a coupling device that can transmit horizontal or vertical force to the tractor! Generally there are two axles for trailers and one axle for semi-trailers. Semi-trailer refers to a vehicle that has no power and is driven by the main vehicle.
Simply put, the drawbar trailer is connected to the front truck with a hook. In long-distance transportation, it is common to have one carriage (or more than one) behind the truck, which is a full trailer. The semi trailer is connected to the towing seat of the tractor through the towing pin. The common container transporter is a typical semi-trailer, and the rear loading part is the semi-trailer.
