The Most Important Thing To Buy Trailer Is The Trailer Beam Process

The beam is the most important load-bearing part of the semi-trailer, but some customers' semi-trailers will break the beam in the process of use, BAPUTI's engineer will analyze why the beam of the semi-trailer will break.
1. The reason of semi-trailer supplier.
1.1 The beam with poor quality steel.
The most direct and easy to understand reason is that the quality of the beam steel used by the trailer factory is not good enough to carry the designed load, resulting in the beam fracture. Some small factories are basically using Q235 in order to save costs, but all BAPUTI's trailers are made of high strength steel.
1.2 Reduce the specification of the beam.
Some trailer suppliers reduce the beam configuration in order to save cost. Mainly to reduce the specifications of the beam, originally 14 thick plate, reduced to 10 thick. Users do not know the situation, still in accordance with the design of the load capacity to pull the goods, beam overload work for a long time, may also cause the beam fracture.
1.3 Poor quality of the beam web.
In addition to lowering the specifications of the beam, some unethical trailer manufacturers to save costs, the web of the beam is connected by two shorter steel, bearing is certainly much worse than the whole one. This means that from the manufacturing completion will inevitably lead to the beam will break, the user should pay attention to check when purchasing the vehicle.
1.4 Welding process is not qualified
BAPUTI uses robot automatic welding, there is no such problem.
1.5 The sales salesman cheated the user.
Some dishonest salesmen pressed the price too low in order to get orders, and the trailer according to this price will be higher than the cost. The factory therefore reduces the configuration of the trailer, originally agreed to be able to pull 50 tons of configuration, the result of the factory down to 30 tons, which can easily lead to the trailer broken beam.
2. The user uses the reason.
2.1 User overload
In addition to the above reasons of the factory, some broken beam situation is the user use unreasonable cause. The most reason is long-term overload, this is easy to understand, the load exceeds the value of the trailer design, the beam can not withstand the weight of the goods, thus leading to breakage.
2.2 Welding operation on the beam.
Users are strictly prohibited to weld on the semi-trailer beam by themselves. Now the trailer beam is mostly high-strength steel, high-strength steel encounters strong current is easy to anneal, the beam is easy to break after annealing.
2.3 The beam bears too much twisting force.
Running curved road, road condition is very poor trailer beam, bear the twisting force than running flat road to be large. The specifications of the upper and lower wings of the beam and the web must be larger, otherwise it is easy to break the beam. Users must pay attention to this one factor when communicating with BAPUTI's salesman.
3. Choose BAPUTI to make the strongest semi-trailer.
BAPUTI has the national leading semi-trailer manufacturing process, advanced automation equipment. The semi-trailer production line is equipped with advanced automation equipment such as laser lowering machine, longitudinal beam CNC production line, plasma CNC cutting machine, automatic longitudinal beam web punching machine, automatic longitudinal beam submerged arc welding machine, automatic frame shot blasting machine, iron plate CNC cutting machine, automatic tightening machine for plate spring bolts, and KTL electrophoresis + powder spraying for the whole vehicle.
The longitudinal beam automatic submerged arc welding equipment can avoid the uncertainties in the traditional manual welding, and the automatic welding equipment makes the trailer longitudinal beam can be formed in one time with uniform and beautiful welding seam. What's more, the beams of the trailers thus formed have good integrity, high strength of the whole vehicle and leading quality in China.
