What is the production process of TITAN semi low loader trailer?

TITAN VEHICLE | 2020-05-19

Now there are more and more semi-trailers running on the road. Many users engaged in long-distance transportation have chosen semi-trailers. But do you know how to make a semi low loader trailer? Today, I will take you to TITAN trailer production workshop in the form of pictures.


Before production, TITAN technical department must first design and produce drawings according to the needs of the user and the market, so that the technical parameters of the main trailer are matched, and then transferred to the manufacturing department.

1. Stage of cutting steel sheet material

According to the drawings of each part produced by the design department, each part is cut out with a CNC cutting machine, such as beam webs, reinforcement plates, standard small accessories and so on.

2. Submerged arc welding beams, beams fixed

The second step is to fix the cut web and the upper and lower wing plates to weld points, and then weld the beam by submerged arc welding.

This step is very important. Both the fixing of the beam and the submerged arc welding are very demanding. If the technical process is not feasible, the beam will have problems. Can the trailer be okay if something goes wrong?

3.Opening, calibration beam, through beam

First cut out the web of the beam to cut out U-shaped holes through which the beams can pass, and then fix the welded I-beams in parallel. The result of comparing the beams is very important. If two I-beams have large parallel errors, very serious tire wear will occur.

4. Connect side beams, welding king pins

At this time, the main beam is basically formed, only the side beams are welded to form the frame structure. And the traction pin traction plate is welded to the position required in the contract, the welding process is required to be high, otherwise the semi low loader trailer will be skewed.

5. Welding frame, welding suspension

At this time, the welding suspension must strictly control the size and maintain the squareness, otherwise it will cause tire wear.

6. Attach the front neck

Attach the front neck

Low bed semi trailer with front neck have this process, and flatbed semi trailer do not have this process. The front neck of the low bed trailer is welded up. Welding is done to strengthen the plate. There is no problem with the strength. TITAN have also considered it in advance.

7. Lay the bottom plate

That is, the bottom plate is fully welded on the frame. There is nothing to say at this step.

8. Frosted and painted

Frosting is the previous step of spray painting. Some manufacturers without shot blasting workshops will blow and polish the welding slag with high pressure gas at this stage.

Spray paint is usually sprayed in a well-ventilated shed. If you want to spray beautifully, you must first look at the coating and the technology of the technicians, but TITAN will spray very beautifully. Basically, you don’t have to worry about this. We will be very attentive!

9. Installation the bottom accessories

After spray painting is completed, the bottom travel system is installed, and the assembled bottom is simply mounted and then precisely adjusted.

10. Install the tire

Everyone is familiar here. It should be noted that the air pressure at the factory is generally not the standard air pressure. You must confirm it again after you buy the trailer.

11. Storage, package and delivery

Seeing this, I believe that everyone has a general understanding of how trailers are manufactured. Choose TITAN can guarantee the quality of the trailer from the manufacturing process.
