Three lines and six axles, commonly known as "crawling on the ground", is the only type of "100 ton king" vehicle that can be used in compliance with the requirements of the household and can run at high speed. Generally, the transportation weight can reach about 80t. If it is four lines, eight axles, five lines, ten axles and other vehicles, the transportation weight is higher, up to hundreds or even hundreds of tons.

Such vehicle models put forward higher requirements for bearing capacity, firmness, bending and torsion resistance, production technology and process of axles and axles.

1. What is the length of the three line six axle axle?

Different from the ordinary axle, the three line six axle axle is generally designed as a group of three axles, which are arranged on one longitudinal axis in turn, as shown in the following figure:

A three line six axle semi-trailer often requires two sets of such axles, which are installed side by side. For example, the following typical three line six axle semi-trailer:

2. How to see the lines and axles of semi-trailer?

Someone may have to ask: How can we tell which lines and which axles are on when so many wheels are installed together?

In fact, the method is also very simple. Take the three line six axle semi-trailer above for example. From the side, the semi-trailer has three rows of axles, which is called "three line";

From the rear, two axles are installed on a row of axles in parallel, a total of six axles, which is called "six axles";

Two tires are respectively installed on both ends of an axle, that is, four tires are installed on one axle, eight tires are installed on one row of axles, and twenty-four tires are installed on three rows of axles.

3. Characteristics of three line six axle axle

More and smaller wheels are the main features of the three wire six axle system.

In fact, strictly speaking, the three lines and six axles belong to a type of low flat vehicle. In the design, the low flat vehicle has the advantages of low center of gravity, convenient loading and unloading, stable driving, and strong passing ability of high limit sections.

The high number of tires increases the contact area between the wheel and the road surface to a certain extent, reduces the pressure on each tire surface, and can play a certain role in protecting the road surface.

4. Application field of three wire six axle axle

The three wire six axle axle is mainly applied to the low platform semi-trailer specially used to transport large cargo. According to the different weight of cargo transported, the three wire six axle, four wire eight axle, five wire ten axle, six wire twelve axle, etc. can be deduced in this way, or enhanced on the basis of three wire six axle.

For example, the "First Ring Road in the World", which was transported from Jinan to Weifang Port some time ago, belongs to the special large cargo transportation. At that time, 96 wheels were designed for the flatbed behind the tractor. From the side view, the car is designed with eight rows of axles. In this way, a row of twelve wheels is calculated according to one axle and four wheels. A row of three axles are installed in parallel, which is equivalent to adding an eight line single axle on the basis of the ordinary eight line sixteen axles. The total number of axles is eight line two fourteen axles.

It is worth noting that although three line six axle vehicles can be legally driven on the road, only three line six axle vehicles can be registered at present, and other models need to apply for temporary license plates, which are usually valid for about one month, and need to be reissued before expiration.

In addition, some regions may have different regulations on the operation route and operation time of these heavy transport vehicles, and specific problems need to be analyzed.

5. Darong Third Line Six axle Axle

At present, the rated load of the six axle axle on the third line of Darong is 80t, and its dead weight is about 3000kg. Other track widths can be customized according to the actual needs of customers.

Super bearing capacity - the steel pipe shaft body thickened with high-strength alloy is used, and the bearing capacity can reach 80t.

Long service life - mechanically connected suspension, simple structure, improved axle strength and extended service life.

Robust and durable - high strength and high precision bearings are selected, which have a long-term effect of low rolling resistance and more reliable performance.

Less destructive force on the road - there are many tires on the axle, reducing the pressure on the road. It can be used on high speed and is suitable for long-distance transportation.

Bending and torsion resistance - the axle beam is not easy to bend, and the bearing force is more reasonable.
