The difference between semi-trailer and trailer:
1. The connection between the semi-trailer and the tractor mainly depends on the saddle and the traction pin. These two parts are the key parts of the semi-trailer connection force.
From the appearance, after the semitrailer is connected with the tractor, the front end of the semitrailer is on the rear end of the tractor, and the steering function is realized through the saddle, as shown in the figure below:
2. The connection between the trailer and the tractor mainly depends on the traction bar, which is hung on the hook of the tractor, as shown in the figure below:
Such connection mode can make the trailer in the driving process to maintain a certain swing or swing up and down, can improve the flexibility of the trailer, more suitable for the use of complex road conditions; at the same time, the difficulty of driving has been improved a lot, especially when reversing and driving. The stability will be affected to a certain extent.
For this reason, trailers are more commonly used in fields, airports, stations and logistics parks than in specialized freight transport scenarios.
For both semitrailers and trailers, the axle used is typically a support axle with no drive or steering capabilities.
The tonnage of semi-trailer bridge is typically between 13t-25t, the main lightweight semi-trailer bridge is about 10t, and the heavy-duty semi-trailer special bridge, such as three-line six-axle, can reach 80t or even hundreds of tons.
In contrast, the tonnage of the trailer is relatively tiny, mostly concentrated in 3t-10t, of which 5t, 8t is the most common. Compared with semi-trailer, trailer axle is more niche, and the parameters are not uniform, most need to be customized.
What's the difference between a semi trailer and a trailer
In our country's transportation industry, the semi-trailer is a kind of widely used model, playing a great role in the transportation of goods. According to the different types of transportation of goods, semi-trailer can be subdivided into fence plate, warehouse grid type, low flat plate, van type, tank type, container type, skeleton type and so on.
Top semi trailer manufacturers claimed that in general, the semi-trailer does not have driving force, so it normally needs to rely on the power of the tractor to drive, that is, the tractor needs to drag the semi-trailer forward. Therefore, numerous car owners are also used to the semi trailer called trailer or towing.
Is a semitrailer the same as a trailer?
Well, not exactly the same model. Although from the model point of view, semi-trailer and trailer refer to their own no power, the need to provide power tractor models, the difference between the two is more obvious. This difference is mainly in the connection with the tractor.
