12. Low loader trailers manufacturing process

After you sign low loader trailers purchase contract with YUHANG VEHICLE, our technicians will make drawings according to the specifications and parameters stipulated in the contract. After the drawings are confirmed, we will arrange production immediately.

Step 1: Cutting stage of steel plate material

First, complete the plasma CNC cutting work of the main beam, side beam, web and other components according to the drawing requirements.

Step 2: Fix the main beam by submerged arc welding

The next step is to assemble the cut web and the upper and lower flanges of the main beam, and then use submerged arc welding to weld them firmly.

Step 3: Main beam opening and throughing

Then cut U-shaped hole on the web of the main beam so that the longitudinal beam can pass through smoothly, and then fix the welded I-beam in parallel. At this time, it is necessary to calibrate the horizontal error of the two I-beams, otherwise the lowbed trailer will be skewed.

Step 4: Connect the side beams and weld the king pin

At this time, the main beam has been formed, and it is only necessary to weld the side beams to form a frame structure, and weld the traction pin to the position specified in the contract.

Step 5: Weld the frame and suspension system

The suspension welding must strictly control the size and keep it vertical, otherwise it will cause tire wear on the 50 tonne lowboy equipment trailers for sale.

Step 6: Fix the front gooseneck

We weld the front gooseneck of the lowbed trailer, and then weld the reinforced steel plate to improve the overall running strength of the trailer.

Step 7: Lay the base plate and weld

The bottom plate is laid, pressed and integrally welded to the frame.

Step 8: Sand cleaning and painting

Painting is a very important link. Before painting, we will scrub and clean the 3 axle lowbed trailer to eliminate welding slag and rust, and improve paint adhesion and aesthetics.

14. How to care and maintain our low bed trailers?

When using low bed semi trailer, attention should be paid to strengthening maintenance and maintenance to increase the flexibility of the vehicle. Here are a few maintenance tips:

1. Tires are the main part of the 4 axle 80 tons low bed trailer that touches the ground. If the road conditions are not good, the speed of tire damage will be aggravated, so you should choose to drive on a flat road as much as possible to improve transportation efficiency.

2. Always pay attention to prevent the vehicle from being overweight. If the load exceeds the regulations, it will accelerate the damage of the vehicle, or even cause a tire burst, which will greatly reduce the service life of the low bed trailer.

3. It is recommended to check the air pressure in the tire frequently to better ensure our transportation needs.

4. During the operation of the vehicle, the chassis is close to the road and is easy to corrode, so we must pay attention to the cleaning and rust prevention of the chassis.

5. During the rainy season, check the electrical system of the vehicle frequently to prevent leakage.

6. The body is waxed and glazed to enhance the corrosion resistance of the trailer and keep the paint surface beautiful.
