It has an axle that can be turned 180 degrees; it is connected to the flatbed semi trailer through an angularly movable drawbar; the drawbar can move vertically and is connected to the chassis, so it cannot bear any vertical force. A semi-trailer with a concealed stand also acts as a drawbar flatbed semi trailer.

A universal drawbar flatbed semi trailer is a towed flatbed semi trailer that carries cargo in an open (flat) or closed (box) cargo space. The material used for the body of the flatbed semi trailer is heavy steel, which is often referred to as: heavy flatbed semi trailer. It is likened to a large and heavy-duty flatbed semi trailer with a relatively strong carrying capacity. Call it a heavy steel flatbed semi trailer. Chonggang flatbed semi trailer is generally used for industrial large-tonnage cargo transportation, which can be turned over in the factory, or the goods can be transported on the road in the middle.

The above picture is an example. The rated load of this vehicle is 150 tons, its length is 12 meters, and its width is 3.5 meters. Because of its long length, it is specially designed to be arched, which strengthens the bending resistance. Design, the arch design on bridges, vehicles and cranes is used here.


Four wheel steering flatbed semi trailer

As shown in the figure below, it is a flatbed semi trailer. The feature of the modified trailer is reverse steering, which aims to improve the maneuverability at low speeds. The four-wheel steering can reduce the turning radius of the vehicle when turning at low speeds. At low speeds, the flatbed semi trailer can reduce the turning radius by up to 20% due to the reverse steering of the rear wheels. The large flatbed semi trailer has the maneuverability and parking agility of a small vehicle. The trailer capacity of the vehicle has been improved. By steering the rear axle to the steering traction of the trailer, the four-wheel steering system greatly improves the maneuverability, stability and safety of the vehicle trailer. This technology is deeply loved by foreign companies.

The vehicle can also be connected section by section to form a flatbed semi trailer group. In many cases, the canopy flatbed semi trailer also has a fence, the function is the same as the luggage flatbed semi trailer, and the use occasions are not the same - airports, railway stations, bus stations, ports and other logistics places.

What precautions are needed for flatbed trucks to pull goods

  • Simply put, it is to loop the rope first, use the second loop to hook the hook and tighten it, and wrap it once on the hook. The same method goes to the next hook position in turn. The first requirement is that the rope is long enough, and the second is that the tail of the carriage is made into two large forks and pulled forward, especially the two upper corners of the cargo at the rear. Because the cargo is easy to loosen, it needs to be pulled twice.

  • Before the diesel engine stops, the flatbed semi trailer should run for 3 to 5 minutes at idle speed to reduce the speed of the supercharger and the temperature, and monitor the running sound of the supercharger. If any abnormality is found, it should be stopped for inspection. If the rotor of the turbocharger is inflexible, there is sticking or wear noise, it must be sent to a qualified repair station for repair.
