4.Processing of low-bed semi-trailers
（1）Frame processing: Rust removal and rust prevention treatment are carried out on the frame to ensure smooth and flat surface. Grind the welding parts to ensure that there are no defects.
（2）Bending of the sidewall: Bend the sidewall according to the requirements of the drawing to ensure accurate shape.
（3）Welding assembly: Weld and assemble the frame, sidewall, chassis and other components to ensure that all parts are tightly connected.
（4）Tire installation: Install the tire on the wheel to ensure that it is firmly installed and there is no air leakage.
5.Debugging and testing of low-bed semi-trailers
（1）Appearance inspection: Conduct a comprehensive inspection of the vehicle appearance to ensure that there are no scratches, dents and other defects.
（2）Dimension inspection: Measure the dimensions of various parts of the vehicle to ensure that they meet the requirements of the drawings.
（3）Performance inspection: Test the power, braking, steering and other performance of the vehicle to ensure that they meet the standards.
（4）Road test: Test drive on the road to test the vehicle’s driving stability, braking distance and other indicators.
6. Packaging and transportation of low-bed semi-trailers
（1）Vehicle cleaning: Clean the vehicle thoroughly to ensure that there are no stains, dirt and other impurities.
（2）Packaging reinforcement: Pack and reinforce the vehicle to ensure that it is not damaged during transportation.
（3）Transportation arrangement: Arrange appropriate transportation methods (such as road, water, air, etc.) according to customer needs and transportation routes.
（4）Handover and acceptance: Handover and acceptance with the customer to ensure that the vehicle arrives safely at the destination.
7. Summary
The production process of low-bed semi-trailers involves multiple links, including design, material selection, processing, debugging and testing, packaging and transportation. During the production process, attention should be paid to detail processing and quality control to ensure the performance and safety of the vehicle. At the same time, full communication and consultation with customers are required to ensure that customer needs are met. Through the above steps, a high-quality low-bed semi-trailer can be produced to provide reliable support for logistics, transportation, construction and other industries.
