Compared to general semi-trailers, van transport semi-trailers are mainly used for long-distance cargo transportation and can be subdivided by type. Different types are suitable for different kinds of goods. For example, dump trucks are suitable for the transportation of bulk goods such as coal, ore, and building materials; tank semi-trailers are used for the transportation of bulk materials and bulk cement; low flatbed semi-trailers are suitable for the transportation of vehicles, machinery, and other heavy loads; warehouse fence-type semi-trailers are mainly used for the transportation of agricultural and sideline products and other light and fluffy goods; and liner-type semi-trailers are used for the transportation of household appliances, textiles, building materials, and palletized goods.
What parts does a van transport semi-trailer consist of? Generally speaking, the structure of a semi-trailer can mainly be divided into the frame, upper part, kingpin, suspension system, running gear, electrical system, support device, protective device, and trailer accessories.
The frame, the main structure for loading goods, consists of the main beam, welded steel, support beams, cross beams, trusses, locks, kingpin connection devices, panels, etc.
The wearing parts refer to handrails, gantry frames, etc., which assist in bearing the load.
The kingpin is an important component that connects the semi-trailer to the tractor and drives the trailer forward under traction.
The suspension system. Generally divided into four types: leaf spring suspension, single-point suspension, air suspension, and rigid suspension, but their performance varies and needs to be selected according to the vehicle's purpose. The device that connects the frame to the axle is mainly used to support the load and mitigate the impact of moving cargo loads.
The electrical system consists of cables, air ducts, and lamps, and its main functions are lighting, braking, and safety alarms.
The support device that supports the trailer when the van transport semi-trailer is detached.
Protective devices can generally be divided into side protection and rear protection.
Trailer accessories such as tool boxes, spare tire racks, plugs, and other fittings.
Compared to single-unit transport vehicles, semi-trailers have better comprehensive economic benefits, can improve transportation efficiency by 30-50%, and can reduce transportation costs by 30-40%, which has played a certain role in promoting the organizational form of the transportation industry.
The above introduction is about what the general structure of a van transport semi-trailer is like.
