Trailer is a kind of vehicle commonly used in the field of transportation. Generally, it refers to vehicles that have no power device and need to be towed by a tractor, such as Trailer RV and camper, which belong to a kind of trailer. Agricultural trailer refers to the trailer used for agricultural mechanized production and transportation, such as common tractors.

Agricultural trailer is an important mechanized transportation mode in rural areas, which is of great significance to improve production efficiency.

In terms of appearance and structure, agricultural trailers can also be divided into full trailer, mid mounted axle and semi-trailer:

1. Full Trailer: the full trailer axle is usually placed at both ends of the trailer, which can evenly bear the load of the carriage. Even if it is not connected to the tractor, it can stand steadily. The weight of the carriage is completely borne by the carriage itself, and the tractor only needs to lead it to run.

2. Middle axle type: the axle of the trailer is installed in the center of the carriage, so it cannot be balanced independently when it is separated from the tractor. When the tractor is connected, the tractor needs to share a part of the weight of the carriage, but this proportion will not be too large. It is mainly supported by the middle axle.

3. Semi-trailer: the axle of semi-trailer is installed at the rear end of the carriage, so it can not keep balance independently. The tractor also needs to bear part of the weight of the carriage.

However, the difference between semi-trailer and semi-trailer is obvious. The semi-trailer is the same as the full trailer and the middle axle, and is connected to the towing hook of the tractor through the towing frame and coupling ring. The front end of the semi-trailer is directly mounted behind the tractor and connected with the traction pin through the traction seat.

Generally speaking, no matter what kind of trailer it is, the towing frame, coupling ring and steering device are generally designed, so it can keep swinging left and right or up and down to a certain extent during driving. This feature can improve the flexibility of the trailer, which is more suitable for the road conditions in the field, but also lead to the increase of reversing difficulty and driving instability. Therefore, agricultural trailers are generally only used for field or short-distance transportation, not for medium and long-distance transportation.

With the improvement of agricultural modernization, the types of agricultural trailers are becoming more and more abundant.

What are the common types of farm trailers? What fields are different types of farm trailers suitable for?

1. Rail Trailer

Fence plate is the most common type of agricultural trailer. The upper part of the carriage is a fence plate structure, which is mainly suitable for the transportation of bulk goods, such as grain, sand, manure, etc., and is widely used.

In addition to the common fence type trailer, there is also a modified high fence type trailer with a height of 1.2m. This type of vehicle can not only transport grain, but also green stored feed, and even remove the baffle when necessary to be used as a flat truck.

2. High rail Trailer

From the aspect of appearance, the high fence trailer is like adding a high fence on the basis of the fence plate. This kind of vehicle is generally used to transport green stored feed, pull grass, etc.

3. Dump Trailer

The self unloading function is widely used in the agricultural field. For example, some commonly used rail cars, high rail cars, flat cars and other models with the main transportation function basically have the self unloading function.

Many of these models have also improved the self unloading function, such as adding spring baffle, which can control the quantity of goods dumped during unloading, cooperate with the forward speed of the vehicle, and also realize flat unloading.

4. Flatbed trailer

Flat trailer refers to a trailer whose body part is directly a flat plate. This type of vehicle is less used in the agricultural field and more used in airports, ports, industries and mines.

According to different transportation requirements, the flat trailer can be equipped with movable guardrails around.

5. Low flat Trailer

The low flat panel trailer is similar to the flat panel trailer, but it is obviously shorter in the height above the ground. When the height above the ground is small, the stability of transportation is improved, it is more convenient for goods to get on and off, and the trafficability of vehicles on some height limited sections is also stronger. Therefore, low platform trailers are generally used to transport mechanical equipment, such as harvesters, excavators, etc. In order to facilitate mechanical boarding and alighting, some models are specially equipped with hydraulic ladders.

6. Skeleton Trailer

The skeleton trailer is similar to the low flat panel Trailer in appearance, except that the chassis structure can be seen directly from above the vehicle body, which is composed of a frame welded by longitudinal beams, cross beams and front and rear end beams. Skeleton trailer can be refitted for mechanical equipment transportation in agricultural field.

7. Liquid fertilizer truck

It can also be called a tank trailer. Generally, spray ports are set at both sides or rear side of the cargo tank, which are mainly used for liquid fertilizer spraying.

8. Solid fertilizer truck

It is mainly used to sprinkle solid fertilizer. A high fence is installed around the top, and a sprinkling device is set at the rear, which can realize uniform sprinkling with the progress of the vehicle.

Some solid fertilizer spreaders can be refitted by fence trailers, which can be used for transportation and manure spreader, and the vehicle application rate has been improved.

9. Straw / grass pickup truck

This pickup truck is mainly used for picking up and collecting scattered grass or straw.

10. Bale pickup truck

As the name suggests, it is used for picking up and loading straw bales, and also for picking up baled straw.

Incidentally, this kind of straw bale pickup truck is generally used in conjunction with straw balers. One baler and one truck can greatly improve the efficiency.

11. Mobile power station

There are many types of mobile power stations, such as hand push type, three wheel type, four wheel type, automobile type, trailer type, etc. the trailer type is generally four-wheel full trailer type, which is mainly used for power supply for field work.

12. Multifunction Trailer

In addition to the above common types of trailers, there are also some multi-functional agricultural trailers in the market, such as trailers that can transport grain, pull harvesters, and pull excavators. These models have different functions and basically cover two or three functions, mainly to improve vehicle utilization and attract more consumers.

Generally, the tonnage of common agricultural trailers is mostly between 3T and 10t, of which 5T and 8t are the most common.

Different from the freight trailers commonly used in the logistics and transportation industry, agricultural trailers are generally used in agricultural production, and different trailers are often required for assistance in different agricultural activities. Therefore, the types of agricultural trailers are relatively richer and their functions are more diverse, resulting in various differences in their appearance, tonnage, track width and other parameters, which to some extent leads to the small number of their parts.

Take the axle as an example. It is relatively simple to buy a 13T drum brake bridge. Almost all manufacturers who can make a trailer bridge have this product, because it is a very popular model in the trailer bridge market, and its parameters are basically very different. Many manufacturers can even provide it in stock. However, if you want to buy a 3T low flat trailer bridge, you need to match the track width and other parameters. I'm afraid it's not so simple, unless it's specially customized.

When it comes to axle customization, it will test our strength. Independent production capacity is the most basic, and product design and quality assurance capability are even more essential. Only in this way can we produce axles that meet customer needs, perfectly match customer vehicles, and have reliable quality and long service life.
