Difference Between Semi-trailer and Full-trailer

[StellaDella]

The difference between the two is: A full-trailer is connected to the front truck with a hook, while a semi-trailer is connected to the tractor's fifth wheel via a kingpin. Below are relevant introductions: 1. Types of full-trailers: There are many types of full-trailers, whose basic frame, body, and running gear are basically the same as trucks. The sideboard-type cargo box is generally made of thin steel plates, with longitudinal concave ribs pressed on the sideboards and transverse convex ribs welded to increase the rigidity of the cargo box and reduce its weight; The floor of the cargo box usually adopts wooden planks covered with thin steel plates or a mixed iron-wood structure; The frame is typically made of 16Mn steel plates, pressed into profiles and welded or riveted together. 2. Uses of semi-trailers: Semi-trailers are mainly used to transport large-volume, indivisible oversized cargo, such as excavators, etc. The fence-type is more suitable for transporting perishable goods like vegetables and fruits. The van-type is more suitable for bulk cargo and moisture-sensitive or relatively valuable goods.
