What is the difference between a "tractor" and a "trailer"?

The difference between trailers: a tractor is a vehicle with only a front but no cargo compartment, a trailer is a vehicle without a cargo compartment welded on it, and a dump truck is a freight truck with its own lifting and lowering columns, which is mostly used to transport scattered goods.

A full trailer refers to an ordinary car with a full trailer compartment added to it, and the two are connected by a hook. A full trailer can increase the loading capacity of the truck, reduce fuel consumption, and thus reduce the cost of transportation.

A full trailer is generally composed of a frame, a body, a traction device, a steering device, a suspension, a driving system, a braking system, a signal system, etc.

A semi-trailer itself has no power. It is composed of a tractor connected to a semi-trailer compartment, which is connected to the tractor through the semi-trailer's traction seat and traction pin.

The advantages and disadvantages of a semi-trailer are as follows:

Advantages: The advantages of a semi-trailer are high stability and relatively fast speed. It is also worth mentioning that the semi-trailer has the advantage of a relatively large vehicle load capacity. After this advantage, any slightly larger cargo can be pulled by a semi-trailer, which cannot be pulled by a full trailer due to its limited length.

Disadvantages: The disadvantage is that the turning radius is too large. The distance from the front of the trailer to the trailer wheel is too long, so the semi-trailer has relatively high requirements for road conditions. So if you want to use a semi-trailer to pull goods, you must observe the road conditions in advance and continue driving if they meet the requirements.

The advantages and disadvantages of full trailers are as follows:

Advantages: Full trailers will be more flexible, and at the same time, the turning radius of the car will be smaller, which is exactly the opposite of semi-trailers.

Disadvantages: Full trailers have high technical requirements for drivers. If the driver's skills do not meet the requirements, he cannot drive a full trailer. In addition, the stability of full trailers is relatively poor, which is not as good as semi-trailers.

The types of semi-trailers are divided into van semi-trailers, container semi-trailers, low-bed semi-trailers, warehouse semi-trailers, wing-type semi-trailers, etc. Among them, low-bed semi-trailers are very common.

Which aspect is the low-bed semi-trailer suitable for: Semi-trailers are the main transportation volume, and it is not easy to split large goods, such as excavators. The fence type is more suitable for fresh goods, such as vegetables, fruits, etc. The semi-trailer is more suitable for hauling bulk goods and moisture-proof and more valuable goods.
