Three axle semi trailer and two axle semi trailer which toll less?

Semi-trailer is a kind of transport model which is widely used in China, among which three-axle semi-trailer accounts for the highest proportion.

Since January 1, 2020, the highway entrance in many provinces has not only taken weighing measures for semi-trailers, but also implemented the mode of charging by axle (type). Under such more complex charging conditions, the market sales of two-axle semi-trailers are quietly increasing, and all kinds of two-axle semi-trailers are frequently seen in the announcements of new cars issued by the Ministry of Industry and Information Technology.

In fact, the old drivers are relatively aware that the two-axle semi-trailer is not an emerging model. In the past few years, some car enterprises launched the two-axle semi-trailer in order to reduce the weight of the trailer, but the popularity was slightly worse until the regulation of charging by the axle was introduced.

Compared with the three-axle semi-trailer, the advantages of two-axle vehicles are mainly shown in the following two points:

1. Highway tolls are reduced.

This is more intuitive, after all, the reduction of a trailer axle, according to the axle charging standard, the highway toll will be reduced accordingly. As for the specific discount how much, still need to be calculated according to the detailed charge standard of each city.

2. The cost of car purchase is greatly reduced.

Without an axle, the cost of buying a new car will naturally fall.

But some owners say: How much money can you save with an axle?

Yes, the cost savings of an axle is not too much, but please do not forget, for the more widely used three-axle fence plate and three-axle grid semi-trailer, according to the provisions of GB7258 is to force the installation of disc axle and air suspension, two-axle semi-trailer is not subject to the restrictions of this new regulation. So the overall calculation, the car cost can save tens of thousands of dollars is almost no problem.

But correspondingly, the disadvantages of two-axle semi-trailer are also relatively obvious:

1. Loading capacity declines.

Take the 6X4 and 4X2 tractors for example. When the tractor is 6X4, the maximum total weight limit of the three-axle semi-trailer is 49t, and that of the two-axle semi-trailer is 43t. When the tractor is 4X2, the maximum total weight limit of the three-axle semi-trailer is 42t and the two-axle semi-trailer is 36t.

It can be seen that the two-axle semi-trailer is 6t less than the three-axle semi-trailer.

2. The outer length size is reduced.

The limits on the outside size of the two axle semi trailer should be differentiated according to the type of vehicle. For example, the maximum length limit of two-axis fence/grid/plate/dump truck is 10m, and the maximum length limit of three-axis is 13m, which is reduced by 3m; The length limit of the two-axle van semi-trailer is 13.75m, the same as that of the three-axle.

Let's summarize the above:

1. If it is a fence/grid/plate/self-discharging semi-trailer, when the three axles are changed to two axles, its purchase cost is reduced, and the carrying weight and the outer length, which is generally referred to as the transportation tonnage and the number of transportation square, are also reduced.

2. If it is a van semi-trailer, when the three axles are changed into two axles, the purchase cost decreases, the transport tonnage decreases, but the number of transport parties does not change.

In this way, it is easier to understand which is more suitable for three-axle semi-trailer and two-axle semi-trailer:

If the owner's transportation is mainly light bubble goods, such as express transportation, two-axle semi-trailer is a good choice, not only the purchase cost is reduced, the operating income can also be basically guaranteed;

If the owner is mainly loaded transportation, especially the fence/grid/plate/self-unloading semi-trailer, although the two-axle car can reduce the early input cost, the follow-up freight is also reduced, compared with the three-axle car to be more appropriate.

In addition, from the objective point of view, special car will also become a development trend in the freight industry, if the owner is still well-off, it is better to buy a compliant three-axle semi-trailer, although the investment cost is relatively high, but the follow-up can transport more kinds of goods, safety and bearing capacity is better, the long-term income may be higher.

Anyway, for the owners, driving safety is the most important, how much money or second. Whether you choose two or three axles, it is recommended that you choose a trailer axle that can be relied on for performance and quality. In the current low freight environment, the more cost-effective products are worth choosing. DARO trailer axle is recommended here. It entered the market in 2001 and has a history of 21 years. It is the fixed cooperative brand of many trailer factories in Liangshan and even the whole country. DARO trailer axle series is rich, complete models, special size can provide customized service, stable and reliable quality, price is not adulterated, to help owners to save comprehensive vehicle costs, improve operation efficiency.
