Advantages and disadvantages of choosing "lightweight" semitrailer

Lightweight semi-trailer has many advantages and is the future trend of development, but there are advantages and disadvantages, there are gains and losses, many truck drivers blindly pursue lightweight, and ignore the product itself. Lightweight semi-trailer direct selling light weight of light-weight high-strength steel brings many restrictions at the same time. Therefore, when we choose trailers, we must look at "light" at the same time, according to their own working conditions and operating environment, to find a large factory with quality assurance to choose suitable trailers, so as to ensure the quality of trailers. Following is everybody's analysis, lightweight, in the end "light" where, let everybody have a rational understanding, rational choice suitable for their semi-trailer.

The weight of trailers is basically several.

First, reduce the actual load interval.

1. The lightening of trailer is to a great extent to reduce the weight of trailer by reducing the specifications of Trailer beams, beams and so on. For example, the height of Trailer beams, which used to be 550 mm, is now even 450 mm for lightening. According to the trailer manufacturer's professionals, even if the light-weight trailer, the best beam height should not be less than 500 mm. How much load and safety will be sacrificed when compared to the weight reduction on the girder?

2. Reducing the specifications of the trailer materials, the overall load-bearing capacity of the trailer will be reduced. For example, the original heavy body trailer can pull 100 tons, ordinary trailer can pull 60-70 tons is not a big problem. Now the light body Trailer generally only pulls 50 tons, reducing the actual load range of the trailer, for the user is to reduce the maximum load.

3. For users with a fixed source of goods, for drivers running bulk goods using light-weight hanging, if not aware of this, or the original thinking of ordinary trailers to pull goods, often overloaded, the problem will come, serious or even broken beams of the accident. This is one of the reasons why many of them feel good quality.

4. Especially the retail customers even know, but sometimes it is difficult to match a good goods, because more than 10 tons do not run, and then in the logistics market for a few days? Plus fluke psychology, problems are not difficult to understand.

Second, better materials, but more stringent for working conditions.

1. It is one of the most important means to lighten the trailer by replacing the lower grade steel with the higher grade steel. It is common to use T700 steel to achieve the same strength, such as using T700 high strength steel, the same strength, manganese steel needs 10 mm thick, T700 may only be 6 mm thick. The weight is reduced naturally.

2. Higher strength steel can reduce the use of steel, reduce the weight of trailers, but different steel characteristics, will also bring other problems. High-strength steel would rather bend than bend, unlike manganese steel with better toughness and bending, the characteristics of high-strength steel girder determine that it can only be suitable for standard transportation in good road conditions, and the best transport in mountain areas is to use manganese steel girder.

3, lighter aluminum alloy is used to lighten the weight, and the weight reduction is more obvious. But the price and maintenance is still a problem.

Third, optimize the trailer design, but the reliability needs to be further improved.

1, another way to reduce the weight of trailers is to optimize the trailer design, such as the forming of a single girder. Although the new technology of one-shot beams can be said to be very effective in lightening trailers, sometimes the new technology also means risks.

2. For example, compared with the traditional I-beam, the weight reduction of the beam is very obvious, but its reliability is doubtful. According to Xiaobian's knowledge, Liangshan first batch of trailers using one-off forming beam, a large part of the broken beam, and the famous factory basically does not use one-off forming beam.

Fourth, trailers use lighter accessories or less accessories.

1. Use lighter accessories to lighten, I believe we all know, such as large single tire, aluminum alloy hub, air suspension and so on compared with the traditional lighter. However, the price is high. We should take into account the ratio of input to output value before purchase.

2. In order to lose weight, some manufacturers or users simplify or even remove some parts of the trailer directly. For example, the toolbox is reduced from two to one, and the toolbox is changed from completely enclosed to fenced, and even the legs are saved. These accessories and so on 7788 although reduces the weight also many, but sacrifices the vehicle use convenience to lighten, sometimes even is safe, is worth pondering.
