Speaking of freight vehicles, we are no strangers, such as some commodities, vegetables, fruits and other materials rely on these vehicles for transportation. The range of freight vehicles is very wide, and it can also be divided into many kinds from the model point of view, such as common trailers, trucks, car trains, trailers, trucks, etc.
1. Trailer
Trailers generally consist of two parts: the towing head and the trailer body. The tractor head is mainly responsible for providing power and driving, and the trailer body is responsible for loading the goods, and these two parts are connected together by a traction saddle and a towing pin to complete the transportation task together.
From the classification point of view, trailers can be divided into semi-trailers, full trailers and mid-axle trailers.
(1) Semi-trailer refers to a trailer whose body cannot be supported independently, and a part of the front of the body needs to be mounted on the rear end of the tractor, and the tractor will bear part of the weight. When the body is separated from the tractor, the balance needs to be supported with special legs.
(2) Full trailer, refers to a trailer that can be completely independently supported, the body can maintain its own balance, can also carry independently, when connecting the tractor, only need the tractor to provide driving force, do not need its share of load.
(3) The mid-shaft trailer, similar in appearance to the full trailer, can also independently bear its own load-bearing, and does not need to be shared by the tractor. The difference is that the axle of the mid-axle trailer is concentrated in the middle part of the body, so it cannot be balanced independently, and outrigger support is also required when separated from the tractor.
According to the different transportation needs, the upper part of the trailer is also different, which can generally be mainly divided into railing type, warehouse type, box type, skeleton type, container type, tank type, low plate type, self-loading type, etc.
2. Trucks
According to Baidu Encyclopedia, trucks can also be called trucks, mainly used to transport goods or towing vehicles, according to different tonnage can be divided into pickup trucks, micro trucks, light trucks, quasi-heavy trucks, heavy trucks, overweight trucks, including integrated models, there are tractor + trailer models.
3. Trucks
In the transportation industry, many people are accustomed to equating trucks with trucks, and even Baidu Encyclopedia indicates that trucks are "also known as trucks". In fact, strictly speaking, trucks are not completely equivalent to trucks, trucks are only a kind of trucks, is specialized in transporting goods, in addition to trucks, trucks also cover cranes, engineering vehicles, etc., the scope is wider.
4. Trailer
When talking about trailers, people often think of wreckers, for example, when the vehicle breaks down or illegally parks, you can call the tow truck to remove the car. In fact, in addition to this meaning, trailers also refer to those bodies that have no driving force themselves, such as logistics warehouses, flatbed trucks used in airports and ports, transport vehicles used in agriculture, fertilizer trucks, grass/straw pickers, trailer RVs used by field workers, camper vehicles, and even micro-trailers dedicated to transporting luggage or motorcycles, etc., all belong to the category of trailers. From this point of view, trailers are more like trailers.
5. Car trains
A car train is a train consisting of one tractor and one or more trailers. From the perspective of model classification, automobile trains can be divided into passenger car trains, passenger car trains, freight car trains, towbar trailer trains, articulated trains, double trailer trains, double semi-trailer trains, flat trains, etc.
With the continuous enhancement of relevant governance in the freight industry, standardization and specialization may be a trend of freight transportation in the future, and various models will also play a role in their respective areas of expertise to jointly improve the efficiency of logistics and transportation.
