A tractor is a general large truck or semi-trailer towed by tools between the front and the trunk, that is, the front of the vehicle can be separated from the original trunk and towed by other trunk, and the trunk can also be separated from the original head and towed by other heads. The front with driving ability is called a tractor, and the rear without driving ability is called a trailer.
The trailer is dragged by the tractor. There are two ways to connect the tractor and the trailer: the first is that the front half of the trailer is mounted on the traction saddle above the rear section of the tractor, and the bridge behind the tractor bears part of the weight of the trailer, which is the semi-trailer; The second is that the front end of the trailer is connected to the rear end of the tractor. The tractor only provides forward tension and drags the trailer, but does not bear the downward weight of the trailer. This is full trailer.
It is often used for the transportation of large quantities of goods in or between workshops, such as the transportation from warehouse to assembly line in automobile manufacturing industry and baggage transportation in airport.
With the rapid development of China's economy and the strong investment of the state in highway construction, highway transportation has become the main mode of transportation in China. As the main equipment of highway transportation, semi-trailer tractor has been widely used because of its strong specialization, large loading capacity and fast transportation. The traction seat is the connecting device between the tractor head and the semi-trailer. Although it is not a very complex and eye-catching component, it is the most important safety equipment of a semi-trailer tractor. If it is misoperated or improperly maintained, it may lead to serious safety accidents.
