Trailer is one of the most widely used models in transportation industry. In real life, if the owner of the relative vehicle modification, generally need to report to the relevant departments, otherwise it will be regarded as illegal modification, will be punished accordingly.So, for the trailer, what changes are considered to be trailer modifications?Range of trailer modifications:1.

Axle is one of the key components on the trailer, is a set of core parts assembly, its performance is directly related to the load bearing, braking and driving of the vehicle. Therefore, the maintenance and maintenance of the axle is crucial to the safety of the operation of the vehicle.In general, trailer axle maintenance mainly includes lubrication grease filling/replacement, fastener detection, brake gap adjustment, brake drum/brake pad inspection, etc.

With the rapid improvement of China's economic level, the transportation industry has also made great progress, especially the road transportation.

As the saying goes: a good horse deserves a good saddle, and the same goes for semi-trailers.

To say that the current general trend of the freight industry is lightweight. Lightweight can not only increase loading capacity and improve transportation efficiency, but also reduce fuel consumption, improve energy saving and emission reduction, which coincides with the road of "cost reduction and efficiency increase" insisted by my country's logistics industry.

Many owners in the purchase of trailer axles, often asked about a parameter is the wheel base, just like choosing clothes to see the size, the wheel base also determines whether the trailer axle can match the vehicle.Generally speaking, under the same load-bearing tonnage, there are often trailer axles with different wheel bases, and how to measure the main vehicle to get an accurate wheel base value?Wheel base refers to the distance between the center line of the track left by the wheel on the vehicle support plane, which can be visually judged by the following figure:Therefore, if the two si

Under normal circumstances, the trailer wants to achieve lightweight, there are the following common ways:1, the use of lighter weight materials, such as aluminum alloy instead of steel, common like aluminum alloy body, aluminum alloy transmission, aluminum alloy drive shaft, aluminum alloy fuel tank, aluminum alloy rim, etc.;2, the vehicle appearance and interior parts use new materials, such as long fiber reinforced materials, low density PP materials, low VOC green materials, spray free materials, halogen-free flame retardant materials, etc.;3, reduce the thickness of the plate, the use of

Flat-bed dump trucks are more common in the transportation of high-density bulk cargo such as sand and gravel. When they go to the household, they are only in the form of a flatbed.

The development of the logistics and transportation industry has brought many conveniences to people's production and life. The types of goods that truck drivers need to transport are also varied, and there are many goods that truck drivers are unwilling to accept orders, even if they run empty. Willing to pull trailer axle.Some car owners made up a jingle for this: "Watermelon is pressed into the car and the coal falls off the scale, peaches are easy to be bumped, rice is pulled into white noodles, and the clean cargo compartment needs to be padded.

In recent years, this combination model of blue light truck + middle axle tow truck has been quite prominent in the vehicle market. When the middle axle tow truck is installed behind the light truck, the car becomes longer, and the cargo loading space is also one more carriage. It seems that one trip can be more than A car of goods before.
