What is the difference between a full trailer and a semi-trailer

Trailers and semi-trailers are connected differently to the front towing vehicle. Full trailers, like semi-trailers, do not have their own power plant. The front end of the trailer is connected to the rear end of the towing vehicle. The tractor only provides pulling force, not load bearing. In a semi-trailer, the front half of the trailer rides on the traction saddle above the rear section of the tractor, and the axle behind the tractor bears part of the weight of the trailer. The most common types of semi-trailers are trailers and large container trucks.

Different uses of trailers and semi-trailers

A full trailer means that a full trailer is attached to the rear of an ordinary truck, and the two are connected by a hook. The full trailer can increase the load capacity of the truck, reduce fuel consumption, and thus reduce transportation costs. Tank-type full trailer-a full-trailer whose loading part adopts a closed tank structure. Flatbed full trailer-a flatbed full trailer with no railings on the floor of the cargo area. Container full trailer - the loading part is a frame structure without a bottom plate, and it is a full trailer specially used for transporting containers. Tipper Trailer - A trailer with an automatic tipping device in the cargo area.

The semi-trailer is connected by the tractor and the semi-trailer compartment, and is supported on the tractor by the traction seat of the semi-trailer. The most common semi-trailers are trailers and large container transport trailers. The cargo parts of the tank semi-trailer, flatbed semi-trailer, container semi-trailer and dump semi-trailer are the same as those of the full trailer.

Full Trailer Introduction

There are many types of trailers, and their basic frame, body, and walking system are basically the same as those of trucks. Railing carriages are generally made of sheet steel. The longitudinal concave ribs are stamped on the railings of the carriages, and the reinforcement ribs are welded horizontally to increase the rigidity of the carriages and reduce the quality of the carriages. The floor of the carriage is generally made of wood and covered with thin steel plates. , or use iron-wood hybrid structure bottom plate; the frame is usually made of 16mn steel plate, which is formed by welding or wicker pressing. The longitudinal and horizontal beams of the frame mostly adopt groove-shaped joint structure, and the front and rear of the two longitudinal beams are arranged with equal width, so that the frame has better bending resistance.

A trailer is generally composed of a frame, a body, a traction device, a steering device, a suspension, a walking system, a braking system, and a signal system.

Brief introduction of semi-trailer

Semi-trailer: A trailer with the axle behind the truck's center of gravity (when the truck is evenly loaded) and fitted with a hitch that transmits horizontal or vertical forces to the towing vehicle.

A semi-trailer refers to a vehicle that has no power itself, is loaded together with the main vehicle, and is driven by the main trailer.
