Considerations When Choosing A Trailer Platform
When choosing a semi-trailer, people often only care about its girders, axles and tires, etc. It is easy to overlook an important thing, that is, the quality of the trailer platform. Whether a trailer is durable or not, the quality of the trailer platform is the key factor. Some car owners have just bought a trailer and drove it for less than a year, and the platform has been dented, deformed or welded. This is most likely because the trailer platform was not selected correctly when the semi-trailer was purchased.
Type of trailer platform
The materials of trailer platform are generally high-strength boards and ordinary boards, and suitable materials can be selected according to requirements. The high-strength board is stronger and more resistant to construction, with high strength, rather than bending, and good resilience. The disadvantage is that the material of the high-strength plate is relatively brittle, and it is easy to crack if it is overweight, but it will not be dented and deformed. After cracking, a steel plate can be placed under the crack for repair welding. The thickness of high-strength plates is generally 1.5, 1.8, and 2.0. Each thickness can make the trailer platform more durable, but the weight will increase by about 200 kg with each increase of 1 mm. Generally, dump truck semi-trailers use more high-strength plates.
Compared with the high-strength board, the general board is soft and easy to dent and deform, but has good impact resistance. The use of a W-shaped bottom plate at the bottom can effectively avoid the problem of dent and deformation of the trailer platform.
The shape of trailer platform is generally divided into flat plate and checker plate. The biggest advantage of checker plate is that it can increase the contact area between the bottom plate and the goods, and play a role of anti-skid. The checkered plate is mostly used in the trailer, and the general thickness is 2.0 and 2.5 mm.
In addition to the two types of trailer platforms introduced above, there is also a special platform – stainless steel trailer platform, whose thickness is generally 1.5 and 2.0 mm, and the thickness can also be increased to improve the strength. In recent years, various industries have increased the cargo capacity of semi-trailers in order to reduce the weight of semi-trailers, and the demand for stainless steel platforms has also increased. And some goods need corrosion resistance for semi-trailers, so stainless steel bottom plates have become popular, which can not only transport corrosive goods with confidence, but also carry ordinary goods, and can also play a role in unloading without residue when loading sand and gravel minerals. The advantages.
Just mentioned that the bottom plate of the semi-trailer has requirements for unloading residues. In fact, in addition to the stainless steel trailer platform, there is also a hard plastic bottom plate that has been applied to the dump semi-trailer. It has a smooth surface and is waterproof and antifreeze. In winter, the cargo and the chassis can be prevented from freezing together.
There are various types of semi-trailers, and the bottom plates are also different. If you choose the wrong one, you cannot play the biggest advantage of semi-trailers. Only the right one is the best.
