Four after eight trucks and a tow two semi-trailer which practical?

"Four after eight" is a category of commercial vehicles, such as common dump trucks, heavy trucks, trailers, many are this category. In popular terms, the "first four" is the front steering wheel for two axes and four wheels, and the "back eight" refers to the back driving wheel for two axes and eight wheels, and each side of the axle is equipped with two wheels. "Four after eight" belongs to heavy vehicles with large load capacity, which are often used in construction projects, long-distance transportation and other fields.

In the past transportation industry, due to the "four after eight" good stability, strong loading capacity, much more cargo pulling, and for the goods "size all", it is favored by many owners. However, after the introduction of GB1589, the treatment of super strength has been greatly improved, the "four after eight" limit weight has been directly reduced by nearly 9t, and the loss of freight has made many owners have to bear the pain and start to look at the 4*2+2 semi-trailer, which is commonly known as "one tow two".

The first four after eight and a tow two semi-trailers, are also four-axle vehicles, what is the difference between the two?

1, cargo capacity: according to the provisions of GB1589, the first four after eight self-weight of about 13t, the load limit of 31t, can be loaded in about 18t of goods; The tow tow weight is about 14t, the load limit is 36t, and the cargo can be loaded is about 22t.

2, loading capacity: the total length of the first four and eight vehicles cannot exceed 12m, the general length of the carriage is about 9.6m, the inner width is 2.5m, the height is 2.5m, the total volume is about 60m³; The maximum length of the one-tow two-compartment type is 13m, the inner width is 2.5m, the height is 2.5m, and the total volume is about 81m³.

Of course, if it is a warehouse or rail-plate carriage, the volume of the two models is not much different.

3, the cost of buying a car: the price of the 400 horsepower first four after eight loading vehicles on the market is generally about 300,000, and the formalities are about 350,000; The price of a tow semi-trailer is about 350,000, and the formalities are about 400,000.

4, driver's license qualification: the first four after eight need B2 qualification, a tow two need A2 qualification.

It can be seen that after the regulation, whether it is on the freight or the cost of the car, a tow two semi-trailers are more suitable than the four after eight trucks, but the purchase cost of a tow two is more or less than the four after eight, and the driving license requirements are higher.

Of course, what car to choose depends on the owner's usual supply:

1, if the source of heavy goods, dumping goods are relatively chaotic, it is recommended to choose a tow two and a half trailer, but need to change the driver's license;

2, if the supply of heavy goods in the majority, it can be some more costs, directly replace a three-axis semi-trailer;

3, if the supply of green pass, discard the majority, then choose the first four after eight, may lose part of the heavy freight fee.

Four or eight trucks, one or two trailers, are often used in the transportation industry, safety and stability is crucial, the axle must choose high-quality products. However, many axles on the market are sold at a high price, and an individual can sell for 9,000 yuan or even tens of thousands of yuan, causing higher cost pressure on the owner.
