The tractor is a general large truck or semi-trailer, which is pulled between the front and the trunk with tools, that is, the front of the truck can be pulled away from the original trunk, and the trunk can also be pulled away from the original trunk. The car with driving ability in front is called tractor, and the car without driving ability in the back is called trailer, which is towed away by tractor.

There are two ways to connect the tractor and trailer: the first way is that the first half of the trailer rides on the traction saddle at the back 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 with the rear end of the tractor, which only provides forward pulling force and drags the trailer without bearing the downward weight of the trailer. This is full suspension.

It is often used to transport a large number of goods in workshops or between workshops, such as transportation from warehouses to assembly lines in automobile manufacturing and luggage transportation at airports.
