Semi-trailers are mainly used to transport bulky goods that are difficult to disassemble, such as excavators, etc. The fence type is more suitable for transporting fresh goods, such as vegetables, fruits, etc. The box type is more suitable for transporting bulk goods and moisture-proof and valuable goods.
Differences Between Semi-trailers
Different from full trailers, semi-trailers have their axles positioned behind the vehicle's center of gravity (when evenly loaded) and are equipped with a hitch that transmits horizontal or vertical forces to the tractor. Full trailers typically have two axles, while semi-trailers have one. A semi-trailer is a vehicle that is unpowered and shares its load with the main vehicle, relying on the main vehicle to pull it along.
Simply put, a full trailer is connected to the truck in front with a hitch. A semi-trailer is connected to the tractor's fifth wheel via a tow pin. A common container transport truck is a typical semi-trailer, with the loading portion at the rear being the semi-trailer.
They also differ in their intended use. Full trailers are primarily used for short-distance transport within factories, ports, docks, warehouses, and other areas, while semi-trailers are primarily used for long-distance cargo transportation.
