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

The difference between a semi-trailer and a full trailer is:

First, the characteristics are different.

1. Semi-trailer: Compared with "monomeric" cars, semi-trailers can improve the comprehensive economic benefits of road transportation. The transportation efficiency is increased by 30-50%, the cost is reduced by 30-40%, and the fuel consumption is reduced by 20-30%.

More importantly, the use of semi-trailers can also play a certain role in promoting the organization of logistics.

2. Full hanging: a vehicle that has no power, is independently loaded, and relies on other vehicles to tow and drive.

Second, the use is different.

1. Semi-hanging: the main transportation volume is large, it is not easy to split large goods, such as excavators, etc., and the fence type is more suitable for fresh goods, such as vegetables, fruits, etc. Van vans are more suitable for pulling bulk cargo, moisture-proof more valuable cargo.

2. Full hanging: widely used in airports, ports, railway stations, factories and large warehouses. It greatly improves the efficiency of cargo transfer and translation. Reduce the cost and labor consumption of forklifts.

Precautions: 1. When turning, pay attention to whether there are pedestrians in the blind spot, especially those who take the battery car, which suddenly appear silently. Be sure to check your tires before traveling.

2. When reversing, the direction is opposite. We should slow down and come back slowly. The scope should not be too large. When we look at things from all sides, we shouldn't panic.

3. If you go far away, it is necessary to check the vehicle, including: the vehicle's half-shaft screw drive screw horn light tire pressure, these are the places where the accident must be compared.

The differences between semi-trailer and full-trailer are as follows:1. The full trailer refers to the addition of a full trailer compartment after the ordinary car, and the two are connected by hooks; The semi-trailer is composed of a tractor car connected to the rear of a semi-trailer car, and they are supported on the tractor by the towing seat of the semi-trailer.

2. The full trailer has front wheels, while the semi-trailer has no front wheels, the full trailer has two axles, and the semi-trailer has only one axle.

3. The locomotive of the full trailer does not need to bear the load of the trailer, but only needs to provide power to help the trailer overcome the friction resistance of the road surface; The semi-trailer needs the locomotive to provide a support point, and the locomotive is responsible for providing power, and it also needs to bear half of the trailer load.

The most obvious difference between a full hanger and a semi-hanger is that the full hanger can stand independently and stand firmly, while the half-hang must stand by the outriggers in front.

The load of the whole trailer is fully borne by the trailer itself, and it is only connected with the main car with a hook. The main vehicle does not need to bear the load of the trailer, but only provides power to realize the traction and steering of the full trailer. Full trailers are mainly used for transportation in docks, factories, ports and other fields.

The semi-trailer is developed on the basis of the full trailer. The semi-trailer is the front half of the trailer on the traction saddle above the rear section of the tractor, and the bridge behind the tractor bears part of the weight of the trailer. The semi-trailer has flexible application and large bearing capacity, especially suitable for long-distance and high-grade road transportation.

Maintenance. Clause. 1. Tire inspection.

The tire pressure should be checked at room temperature every month, and if it is lower than the normal standard, the tire pressure should be replenished in time. The air pressure should not be too high or too low, otherwise it will affect the safety of driving. Check the cracks of the tires, and replace the tires in time when there are potential safety hazards.

When choosing tires, they should be of the same type.

Clause. Second, the maintenance and inspection of the battery.

Check whether the battery is firmly fixed, the electrolyte should be between the upper and lower limits, and the electrolyte or distilled water should be added to the high line in time when it is close to the lower line. Keep the positive and negative cables of the battery in good contact, and keep the battery clean and dry. Vehicles that have been placed for a long time should take off the positive and negative cables of the battery, rewire and start the engine about 20 minutes after about half a month, and charge it in time if the power is obviously insufficient.

Clause. 3. Check the liquid level of the clutch master pump.

If the clutch level is between high and low, it means normal, if it is below the standard line, it may be that the main cylinder or sub-pump bowl is damaged. In the engine running state, it will be difficult or impossible to engage the gear, please go to the nearest maintenance station for maintenance.

The difference between semi-trailer and full-trailer is that the towing method is different for both models.

The full trailer can be independently supported and steady, and the semi-trailer must rely on the outriggers in front to stand, the load of the full trailer is all borne by itself, and the tractor is connected with a hook, the tractor does not need to bear the load of the trailer, but is used to provide traction, the semi-trailer is provided by the tractor to provide the support point, in addition to providing power, it also needs to bear the load of the trailer.

The upright mode adopted by the full trailer is that the full trailer can rely on its own tires to stand upright, the upright mode adopted by the semi-trailer is that it must be supported by the outriggers in front, the full trailer has front wheels, the semi-trailer has no front wheels, the full trailer has two axles, the semi-trailer has an axle, the stability of the full trailer at high speed is relatively poor, the emergency braking ability is relatively poor, on the contrary, the high-speed stability and emergency braking of the semi-trailer are better.

Semi-trailer is the most commonly used, but also the most familiar model, there are many types of semi-trailer, divided into flat type, gooseneck type, concave beam type, because the body length of the semi-trailer is relatively long, so the use of the semi-trailer is more flexible, the carrying capacity of the body is relatively strong, especially suitable for long-distance transportation, the semi-trailer has become one of the most important means of transportation.

The full trailer is connected with the truck in front with a hitch. The semi-trailer is connected with the traction seat of the tractor through the towing pin, and the common container transporter is a typical semi-trailer train, and the rear loading part is the semi-trailer.

There are also differences in use, full trailers are mainly used for short-distance transportation in factories, ports, docks, warehouses and other fields, while semi-trailers are mainly used for long-distance transportation of goods.

Classification of semi-trailers.

The dump semi-trailer is suitable for the transportation of bulk and scattered goods such as coal, ore, and construction materials.

The on-board part of the low-bed semi-trailer has no steeplechase and is widely used, mainly used for medium and long-distance freight transportation. The frame of the series semi-trailer is a piercing beam structure, and the longitudinal beam adopts a straight live gooseneck type.

The stake semi-trailer adopts the fence structure design for the cargo part of the stake semi-trailer. It is mainly used for the transportation of agricultural and sideline products and other light foam goods.

The cargo part of the container semi-trailer is a semi-trailer with a container structure. It is mainly used for ships, ports, routes, highways, transfer stations, bridges, tunnels, and multimodal transport supporting logistics systems.

The structure of the cargo part of the tank semi-trailer is a semi-trailer with a tank structure. It is mainly used for transporting liquids, bulk materials and bulk cement.

The van semi-trailer series products are used for the transportation of household appliances, textile goods, coal, sand and other building materials and map goods.

Dump truck body is equipped with an automatic dumping device. Also known as dump truck, engineering vehicle, it is composed of automobile chassis, hydraulic lifting mechanism, power take-off device and cargo compartment. In civil engineering, it is often combined with excavators, loaders, belt conveyors, etc., to form a loading, transportation and unloading production line for the loading and unloading of earthwork, sand and gravel, and loose materials.

There are differences between semi-trailers and full trailers in terms of upright mode, front wheels, axles, and composition.

1. Upright mode. The full trailer relies on its own tires to stand upright, and the semi-trailer must rely on the outriggers in front to stand upright.

2. a front wheel. Full trailers have front wheels, semi-trailers have no front wheels.

3. a shaft. A full trailer has two axles and a semi-trailer has one axle.

4. Composition. The full trailer is composed of a frame, a body, a traction device, a steering device, a suspension device, etc. The axle of the semi-trailer is placed behind the vehicle's center of gravity and is equipped with a trailer that transmits horizontal or vertical forces to the tractor coupling.

What is the tonnage standard for semi-trailer load load?

In general, the double rear axle is 18 tons, and the triple rear axle is 24 tons. The position of the towing pin should be calculated according to the tractor. The sum of two digits and the subtraction of the dead weight is the rated load weight. Look at the full weight of several axles and 6 axles (car plus cargo) The maximum load capacity of a 55t semi-trailer is not more than 35 tons.

Highway regulations: 10 tons for a single shaft. The six-axis most celestial index is 55 tons high.

Summary. Hello dear dear, the difference between a semi-trailer and a full trailer: the connection method is different from that of a tractor:

Full trailer, the load is all borne by themselves, only connected with the tractor by the hook, the tractor does not need to bear the trailer load, only provides traction; Semi-trailers, tractors provide support points and power, but also bear part of the trailer load. <>

<> the difference between semi-trailer and full-trailer.

Hello dear, the difference between semi-trailer and full trailer: the connection method is different from that of the tractor: full trailer, the load is all borne by themselves, only connected with the tractor bridge car through the hook, the tractor does not need to bear the trailer load, and the tractor only provides traction; Semi-trailers, tractors provide support points and power, but also bear part of the trailer load.

<> semi-trailer or trailer is a trailer with the axle behind the vehicle's center of gravity and equipped with a coupling device that transmits horizontal and vertical forces to the tractor. Semi-trailers are generally three-axle semi-trailers with positive belts, and their types are divided into 11-meter warehouse semi-trailers, 13-meter warehouse columns, low-bed semi-trailers and other types. It is a kind of heavy-duty transport vehicle that is connected with the semi-trailer head through the towing pin.

There are many types of <> trailers, and their basic frames, bodies, and walking systems are basically the same as those of trucks. The steeplechase carriage is generally made of thin steel plate, the longitudinal concave ridge plate is stamped out on the steeplechase of the carriage, and the transverse rib is welded with a rib to increase the rigidity of the compartment and reduce the quality of the carriage. <>

Definition of full trailer: It is a single pallet or trailer composed of a frame, a turntable mechanism and a hook, which bears the full mass of the goods. To put it simply, the front end of the trailer is connected to the rear end of the tow tractor, which only provides pulling force and does not bear weight.

Definition of semi-trailer: The front half of the trailer rides on the towing saddle above the rear section of the tractor, and the bridge behind the tractor bears part of the weight or most of the mass of the trailer, and the other part of the mass is shared by the trailer.

tractor, which refers to the front of the car; A trailer is the tail of a car that is used to load cargo. There are two main differences between a full trailer and a semi-trailer:

1.The endurance of the tractor is not the same. The full trailer tractor only needs to be pulled; The tractor of a semi-trailer requires not only traction, but also load.

2.A full trailer can stand upright on its own tires, and a semi-trailer must stand upright on the front legs.

Most of the common trailers on the road are semi-trailers; The most iconic trailer is the train. Full trailers are mainly used for short-distance transportation in factories, ports, wharves and warehouses, and semi-trailers are mainly used for long-distance transportation of goods.

The full trailer has an advantage in mountainous areas or on rough roads, because the drawbar can swing flexibly relative to the body. However, the shortcomings are also very prominent, that is, the stability of the full trailer is poor when driving at high speed, and it is prone to fatal hidden dangers such as braking and tail flicking. In addition, there have been major traffic accidents caused by the rupture of the towing frame in history.

So at present, almost all semi-trailers in China have been replaced by semi-trailers.

The difference between the full trailer and the semi-trailer is: the full trailer is connected to the locomotive, the load is borne by the free body, and the locomotive is only connected with the hook, the locomotive does not need to bear the trailer load, and only provides power to help the trailer overcome the friction resistance of the road surface; The semi-trailer needs the locomotive to provide a support point, and the locomotive is responsible for providing power, and it also needs to bear half of the trailer load. It's like two people carrying a piece of wood, the person in front is a locomotive, and the person in the back is a semi-trailer.

Different uses of full trailer and semi-trailer:

Full trailer, that is, refers to the ordinary car after the addition of a full trailer car, the two are connected by a hook. The full trailer can increase the loading capacity of the truck, reduce fuel consumption, and thus reduce transportation costs.

Tank trailer - a full trailer with a closed tank structure for the cargo part.

Flatbed full trailer - the floor of the cargo part is a flat structure and there is no steeplechase full trailer.

Container full trailer - a full trailer with a frame structure and no floor, which is specially designed to transport container compartments.

Dump full trailer - a full trailer with an automatic dumping device at the cargo part.

The semi-trailer is composed of a tractor car connected to a semi-trailer car, and they are supported on the tractor by the traction seat of the semi-trailer. The most common semi-trailers are trailers and large container trucks. Tank semi-trailers, flatbed semi-trailers, container semi-trailers, dump semi-trailers, the cargo part is the same as the full trailer.
