What kind of semitrailer does it take to pull 100 tons legally?

Overload is a perennial problem in the logistics transportation industry, many semi-trailer drivers in order to earn more freight at risk, the load can reach 70t, 80t or even 150t, although the short time to see the freight is much, but it endangers the safety of public transport, damage the road, disrupt the transportation market, resulting in the industry freight prices fall again.

In recent years, the attention of relevant departments to the logistics and transportation industry shows a rising trend, and the management of over-limit or overload may gradually become a task with strong sustainability. After the introduction and implementation of GB1589, the maximum allowable total mass limit of many models has also changed.

According to the new version of GB1589 standard, the maximum load limit of cargo vehicles is 49t. Does that mean that goods over 49 tons can't be legally transported on the road? Not so. Those heavy goods weighing up to 100 tons or even hundreds of tons can be legally transported on the road, but "special vehicles", need to comply with the model can be. That's what we call a "big transporter."

In general, bulky transport vehicles can be divided into four classes:

1. Level 1: Meet one of the following standards

Length greater than 14 meters (including 14 meters) and less than 20 meters;

Width greater than 3.5 meters (including 3.5 meters) less than 4.5 meters;

Height greater than 3 meters (including 3 meters) less than 3.8 meters;

The weight is greater than 20 tons (including 20 tons) and less than 100 tons.

2. Level 2: Meet one of the following standards

Length greater than 20 meters (including 20 meters) less than 30 meters;

Width greater than 4.5 meters (including 4.5 meters) less than 5.5 meters;

Height greater than 3.8 meters (including 3.8 meters) less than 4.4 meters;

The weight is greater than 100 tons (including 100 tons) and less than 200 tons.

3. Level 3: Meet one of the following standards

Length greater than 30 meters (including 30 meters) and less than 40 meters;

Width greater than 5.5 m (including 5.5 m) and less than 6 m;

Height greater than 4.4 meters (including 4.4 meters) and less than 5 meters;

The weight is greater than 200 tons (including 200 tons) and less than 300 tons.

4. Level 4: Meet one of the following standards

A length of 40 meters or above;

Width of 6 meters and above;

The height is 5 meters or above;

The weight is 300 tons and above.

As for the large transport vehicle model, it is often said that three lines six axis, four lines eight axis, five lines ten axis, six lines twelve axis, seven lines fourteen axis, eight lines sixteen axis, etc. Among them, three lines six axes can generally transport 80 tons of goods, four lines eight axes can be allowed to transport 100 tons of goods, five lines ten axes can be allowed to transport 120 tons of goods, and so on.

It is worth noting that, although these models are legal on the road, but only three-line six-axle semi-trailer can be applied for household, the rest need to apply for temporary license, the period of validity is usually about one month, need to be reapplied before the expiration. In addition, some regions may have different regulations on the operation route and operation time of these heavy transport vehicles, which needs to be analyzed on a case-by-case basis.

So, how to see the semi-trailer how many lines and axles?

It's very simple. Look at the semi-trailer behind the design of a few rows of wheels, that is, a few lines; Then look at these rows of wheels in the middle of a total of several axles installed, that is, several axles. For example, three-line six-axis semi-trailer refers to that three rows of wheels are installed on the semi-trailer, which is called "three-line". Two axles are installed on a row of wheels, which is a total of six axles, which is called "six-axis". And so on.

Compared with the ordinary semi-trailer, the large transport semi-trailer has the advantages of large load, uniform wheel and axle load, small turning radius and so on. At the same time, the requirements for the vehicle chassis components are relatively high. DARO trailer axle is the representative of Shandong Liangshan commercial vehicle production base of the axle enterprise, so far has accumulated 20 years of trailer axle production and manufacturing experience, especially in the integrated axle casting process is at the leading level in China. Compared with the traditional three-joint welded axle, the all-in-one axle has stronger heavy load performance, can better meet the transportation needs of large transport vehicles, and can provide customized services according to the actual needs of customers.
