Brief Introduction of 3 Axle 40ft Cargo Fence Semi Trailer
The 3 axle 40ft cargo fence type semi-trailer refers to a semi-trailer with a fence structure installed at the loading part. It is mainly used for the transportation of agricultural and sideline products and other light foam goods. It is also one of the commonly used transportation tools for consignment stations and express companies. In order to adapt to the transportation of different goods, the types and structures of cargo fence grid semi-trailers have been continuously improved in recent years. They are even called "magic oil" by industry insiders, which shows its wide range of applications.
40ft cargo fence semi trainer is the most commonly used one.

Categories of 3 Axle 40ft Cargo Fence Semi Trailer
Single Layer and Double Layer
These two 3 axle 40 ft cargo fence semi-trailers are relatively common and they are also the earliest cargo fence trailer structures. The height from the bottom plate of the single-layer cargo fence grid to the top of the cargo fence grid is generally within 1800mm, while the height of the double-layer cargo fence grid is more than 1800mm.
As mentioned before, these two 3 axle 40ft cargo fence semi-trailers are mainly used for long-distance transportation. The types of goods loaded are mainly agricultural and sideline products, steel, and bulky light foam goods.
Long Lock Rod and Short Lock Rod cargo fence semi-trailer
The long-lock bar 3 axle 40ft cargo fence semi-trailer is developed on the basis of the early coal transport van semi-trailer. Its top is open, which is convenient for loading. The surrounding is closed with canvas, which is similar to the van semi trailer in function. Generally, when the length of the body is more than 11m, 3 pairs of doors are designed on each side. Then the length of the body is less than 11m, 2 pairs of doors are designed on each side. When the side doors are fully opened, the size can meet the loading and unloading requirements of construction machinery. The goods transported by this type of vehicle are mainly coal, sand and gravel materials.
Compared with the long lock rod, the short lock rod 40ft cargo fence semi-trailer has no edge at the top. The lock rod is shorter and the height from the bottom plate to the top of the cargo fence grid is generally no higher than 1800mm. Because there is no upper side wall, the anti-swelling ability of its cargo fence grid is poor. In addition to transporting coal, sand and gravel, this cargo fence semi-trailer can also carry out long-distance logistics transportation.
Straight Beam Type and Gooseneck Type
Straight beams, commonly known as "straight plates", are currently mostly used for bulk cargo transportation such as coal, grain, sand and gravel, etc. They are relatively convenient to load and unload.
The gooseneck beam is commonly known as "high and low plate". The height difference between the bottom plate and the gooseneck of 3 axle cargo fence semi trailer is generally about 200mm. Compared with the straight beam structure, the loading space is larger and the center of gravity of the goods is lower. It is suitable for general cargo transportation with relatively low density and large curvature of road conditions such as mountain coal transportation. The production process of the gooseneck type cargo fence trailer is more complicated than that of the straight beam type. Generally, with the same configuration the gooseneck type cargo fence trailer is more expensive.
Trend of 3 Axle 40ft Cargo Fence Semi Trailer
In the past ten years, the 40ft cargo fence semi-trailer has achieved rapid development in China, which is mainly due to its advantages such as strong specialization, large loading capacity, fast transportation, convenient disassembly, high functionality and low investment cost.
In particular, with the increase of semi trailer control, lightweight models are more and more popular with car owners. Compared with the van semi-trailer, the curb weight of the 3 axle cargo fence semi-trailer can be 2t-3t lighter. The standard 13m cargo fence grid has a dead weight of 6t-6.5 tons. It has obvious advantages in the fields of energy saving and environmental protection so it is gradually replacing the van semi-trailer.
