The types of flatbed semi trailers are not limited to what I just mentioned, because this is a non-standard vehicle and is very flexible, so the production is completely designed and manufactured according to actual use. So, what I'm introducing today can only be said to be very rare in the big family of flatbed semi trailers.
Performance of flatbed semi trailer:
1. Double spring buffer type traction mechanism, there is a buffer to avoid damage to the goods when the vehicle starts or brakes suddenly.
2. The steering mechanism is Shanghai Industrial Machinery slewing assembly (excavator hook arm slewing assembly), so there is no need to worry about damage for ten years.
3. The traction cage can be adjusted and fixed up and down, and it is only necessary to adjust the traction head or forklift of different tonnages.
4. The suspension frame, compared with the traditional hard connection (welding), reduces the long-term stress damage of the car body and has a longer service life.
5. The axle is automatically oscillated and adjusted, and the convex and concave ground ensures the level of the board and the balanced force on the tires.
6. The front and rear wheel sets can be equipped with spring steel sheet shock absorbers to reduce the damage to the goods caused by bumps.
7. Equipped with universal joint, the operation is very flexible.
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.
Application of Flatbed Transporter
