How many axles is a semi-trailer? Trailer axle which is good?

In recent years, China's logistics and transportation industry has gradually developed in the direction of intensification and efficiency, and logistics enterprises have more urgent needs for efficient vehicles. Compared with the "monomer" vehicle, the transport efficiency of the semi-trailer can be increased by about 30%-50%, but the transport cost is reduced by about 30%-40%, therefore, the application of the semi-trailer in the transport of goods is more and more extensive.

So, how many axles is the semi-trailer we often say?

The so-called "semi-trailer" is relative to the "full trailer", referring to the axle is placed behind the center of gravity of the vehicle (when the vehicle is evenly loaded), and is equipped with a coupling device that can transfer horizontal and vertical forces to the tractor. To put it informally, a semi-trailer is a vehicle that needs the front to bear part of the weight of the trailer, as shown in the figure below:

The full trailer is a vehicle that can fully bear its own weight, and is connected with the front of the front with a hook, and only needs the front traction, as shown in the following figure:

Under normal circumstances, the semi-trailer refers to the three-axle semi-trailer, In terms of classification, it can be subdivided into dump semi-trailer, low plate semi-trailer, warehouse grid semi-trailer, container semi-trailer, tank semi-trailer, van semi-trailer, oil transport semi-trailer, light semi-trailer, vehicle transport semi-trailer, powder material transport semi-trailer, chemical liquid transport semi-trailer, heavy low plate semi-trailer, plate semi-trailer, swan neck semi-trailer, skeleton container semi-trailer Trailer, 17m 5 low flat semi-trailer, bulk cement tank transport semi-trailer, etc.

For semi-trailers, safety and reliability are crucial and directly related to transportation safety and transportation economic benefits. The performance of the semi-trailer depends largely on its chassis components, that is, the excellent performance of the axle system, especially the braking system of the vehicle is also dependent on the axle, and its importance does not need to be said. Therefore, choosing the right axle is choosing the right safety and economic benefits.

However, the axle market of a variety of products, many owners in the face of a variety of brands when the difficulty, how to choose? Which is better?

In fact, like other consumer goods, can withstand the test of the market, is a good brand. DARO trailer axle is the leader in the domestic trailer axle market.
