Is aluminum semitrailer worth buying?

Aluminum alloy semi-trailer refers to the carriage, side protection, rear protection, traction seat plate, suspension, hinges, roof rod, etc. are all made of aluminum alloy material, instead of the traditional steel structure. Aluminum alloy semi-trailer in Europe, the United States, Japan and other countries have a high penetration rate, most steel trailer has been replaced by aluminum alloy trailer, there are many domestic trailer enterprises launched aluminum alloy semi-trailer products, but the popularity is far less than developed countries.

In spite of this, the voice of the aluminum alloy semi trailer in the industry is relatively high, some industry insiders say that the all-aluminum alloy semi trailer is "the future star of the transportation industry", in fact, it is not unreasonable. From the general trend, resource consumption and environmental pollution has become a global problem, the whole society is concerned about how to save energy and reduce emissions, heavy diesel vehicles are one of the sources of air pollution, how to reduce vehicle fuel consumption, improve transport efficiency, reduce air pollution has become a concern of all countries. Aluminum alloy semi trailer caters to the trend of energy saving and emission reduction.

Let's first summarize the advantages of aluminum alloy semi-trailer:

1. Lightweight.

This is no doubt, compared to traditional steel structure, aluminum alloy material is an obvious advantage of light weight. It is understood that the car is this one, aluminum alloy semi trailer can be lighter than the traditional semi trailer in weight about 3 tons, if you count the rim, suspension, a car can be reduced than the steel structure about 3.5 tons.

2. Strong transportation capacity.

This is closely related to lightweight. The vehicle's weight is 3.5 tons lighter, meaning that aluminum semitrailers can carry 3.5 tons more cargo per operation than steel semitrailers. Someone has calculated an account, assuming a semi-trailer a year of operation of 150,000 kilometers, an aluminum alloy semi-trailer can be more than the traditional steel structure of the semi-trailer income of about 150-180,000 yuan, is also a not small income.

3. Save fuel.

Because the weight of the aluminum alloy semi trailer is reduced, the oil consumption of the aluminum alloy trailer is much lower when hauling the same weight of goods, and its fuel consumption in no-load operation will be greatly reduced. According to relevant statistics, if the domestic aluminum alloy semi-trailer market share can reach 70%, then a year can save 7.66 million tons of fuel, reduce carbon dioxide emissions 22 million tons.

4, long service life.

According to the use experience of developed countries, the life cycle of an aluminum alloy tank is about 15-20 years, but the life cycle of steel tank is only 7-9 years. In addition, from the recycling value of scrapped vehicles, the recycling value of aluminum tank cars is much higher than that of steel structure vehicles, which is also part of the income.

5, strong safety performance.

The reduction of vehicle weight can not only improve the carrying capacity, but also help to reduce the burden of the braking system, which can improve the safety of long-distance transportation virtually.

It can be seen that the advantages of aluminum alloy semi trailer are indeed many, comprehensive analysis, almost all from one factor: weight reduction. Supposedly, this should be an advantage that the majority of owners are very welcome, but the speed of the implementation of aluminum alloy semi trailer in the country is not satisfactory. Why is that?

The emergence of many new things, always like a double-edged sword, has advantages, also has disadvantages, aluminum alloy semi trailer is no exception. Let's take a look at the shortcomings of aluminum alloy semi-trailer:

1, the building resistance is not as good as steel structure.

Aluminum alloy material is indeed dominant in weight, but corresponding to it, is not as durable as steel structure. Especially for the semi-trailer, if it is to transport coal, steel, sand and stone and other heavy goods, bumps and bruises are inevitable, aluminum alloy material can withstand such a toss? Although many car companies in the publicity that its building strength is reliable, but it is still difficult to change the owners of the fixed impression. Especially our country's complex terrain, transport road conditions vary, such as some mountain road transport for the strength of the vehicle is very high, aluminum alloy trailer can be suitable for such transport conditions, I'm afraid we have to speak to the facts, relying on advertising is difficult to convince the public.

2, maintenance is not convenient.

After all, it is a new product, aluminum alloy semi-trailer in many process requirements are more advanced than the traditional steel structure, such as welding, aluminum alloy material welding requirements with argon arc welding, if the equipment or technology is not up to standard, it is likely to damage the material performance, affect the vehicle strength.

3. The toughness is relatively poor.

The elasticity of aluminum alloy material is not as good as that of steel structure, and it is afraid to be more bumpy than the traditional steel structure. Of course, this point can be improved or made up through parts, such as air suspension, can be very good to improve this shortcoming, but the price of air suspension is expensive, or let a lot of owners have little money.

It can be seen that the popularity of aluminum alloy semi trailer, I am afraid that there is still a long way to go, when these problems to find solutions, perhaps its market share can be further.

The lightweight of semi-trailer has always been the concern of the industry. Replacing aluminum alloy material is one method. In addition, starting from parts to reduce the weight of the vehicle to achieve weight reduction is also a way. For example, the rear axle of semi-trailer, as a key part of the vehicle bearing, its lightweight is a task to test technology and strength. DARO Group is one of the companies that has successfully developed lightweight trailer axles.

As a trailer axle enterprise established 20 years ago, DARO Group has always spared no effort in independent innovation. As early as 2006, DARO Group independently developed the leading domestic integrated axle production equipment, becoming the first enterprise in Liangshan special vehicle production base to mass-produce integrated axle. At present, DARO Group actively caters to the trend of lightweight reform, from the raw materials, technology, design, technology and other aspects of the research and development of lightweight axle, compared with the traditional axle weight reduction of more than 15%. Its product line is rich and diverse, fully meet the different needs of owners.
