1.Advantage of China 80-120 Ton Low Bed Trailers?
1). Connect side beams and weld king pins
At this time, the main beam is basically formed, and only the side beam is welded to form a frame structure.And the traction pin traction plate is welded to the position required in the contract, the welding process requirements are high, otherwise the low bed trailer will skew.
2) submerged arc welding beam, fixed beam
The second step is to fix the cutting web and upper and lower fins to the solder joints and then weld the beam with submerged arc welding.
3). Hole opening, calibration beam and pass beam
First cut the web of the beam, cut out the U-shaped hole through which the beam can pass, and then hold the welded I-beam in parallel.The results of beam comparison are very important.If there is a large parallel error between the two I-beams, the tire will suffer very serious wear.
4). Sheet cutting stage
According to the drawings of each part made by the design department, cut each part with CNC cutting machine, such as beam web, reinforcement plate, standard small accessories, etc.
5). Welding frame and welding suspension
At this time, the welding suspension must be strictly controlled size and maintain perpendicularity, otherwise it will cause the wear of the low pin tire of the loader.
