In summer, there is more rain, and vehicles are prone to soaking in water, especially in those low-lying places.Although the body of the trailer is relatively higher than that of ordinary vehicles, there is still a risk of soaking in water if it encounters a violent rainstorm.

Affected by the typhoon in the past few days, there have been large-scale torrential rains across the country. Many cities have encountered the strongest precipitation that has not been seen in many years. The urban waterlogging is serious, which poses a great threat to people's production and life and even the safety of life and property trailer axle.Such extreme weather has also brought great challenges to logistics and transportation.

In recent years, the development scale of cold chain transport is getting larger and larger, many industries such as catering, fresh, pharmaceuticals, etc., need cold chain transport to provide support, so the cold chain transport market is also continuing to improve, and the number of refrigerated trucks is also increasing year by year.Compared with ordinary owners, it seems to be more profitable to drive refrigerated vehicles, it is said to earn 8,000 to 10,000 a month, fixed supply, 20-30,000 a month is very common.

Once upon a time, the logistics and transportation industry was the most popular way to make money. At that time, the number of semi-trailers was less, the goods were more and the supply of goods was stable. It was almost possible to buy a car, the income was stable, and the time was free.Nowadays, the domestic economic level is constantly improving, and the development of various industries is to a higher level than before.

With the continuous improvement of the requirements for cargo transportation in all walks of life, there are more and more subdivided fields in the freight industry. Different transportation fields also put forward different requirements for the types of vehicles, so the concept of "special vehicle for special use" came into being.

As a special purpose vehicle with a large market share, self-discharging semi-trailer is widely used in the transportation of loose goods such as sand, gravel, soil and coal. Its loading carriage can automatically tip over at a certain Angle during unloading, which greatly saves unloading time and labor, shorens transportation cycle and improves production efficiency.At present, the self-dumping semi-trailer on the market is mainly divided into two kinds: post-tipping self-dumping and rollover self-dumping.

"Semi-trailer", "full trailer", "middle axle trailer", what is the difference between them? How to tell the difference? Next, we will introduce these three types of trailers separately.The semitrailer needs to rely on legs to achieve balance after it is released from the tractorA semi-trailer is a trailer that is pulled by a semi-trailer tractor and bears part of its weight.

Oil, also known as engine oil, is an indispensable oil on the vehicle, its role in addition to the well-known lubrication and wear reduction, but also can play an auxiliary cooling, sealing leakage, rust, corrosion, shock buffering and other functions, if not it, the engine is easy to appear gas, rust, melting and even direct scrap.Like other oil on the vehicle, the oil also has an oil change cycle, and it is not a one-time addition that can be completely replaced, because the oil will also be oxidized, acidified, dissolved sludge, etc., during the use of the oil, which will not only make the

Dump truck is a kind of engineering vehicle. Its principle is to drive the hydraulic mechanism through the engine, drive the lifting mechanism to complete the incline to achieve the purpose of unloading, reset after the completion of unloading, greatly save the unloading time and labor, shorten the transportation cycle, improve the production efficiency. It is widely used in mining, water conservancy construction, road construction and other fields.From the lifting way of the dump truck, it can be divided into rear and cartwheel type.

At present, many large logistics companies adopt a mode of transportation. As the name implies, it is to use the tractor to tow the trailer to the destination, put down the goods together with the trailer, and then drag other trailers filled with goods to another place, to achieve continuous vehicle operation.Thus it can be seen that the trailer is not a type of vehicle classification, but a mode of transport, the more accurate name should be the sling transport.
