The low bed trailer is used to transport super-high or super-heavy goods that cannot be transported by standard semi-trailers, such as large machinery, excavators, road rollers, etc. The chassis of the low-bed trailer is the lowest of all semi-trailers. The overall structure is low in the middle and high on both sides or high in the front and low in the back. The height of the low bed trailer will be made according to the customer’s requirements.
The following height is an example of 3 axles. The gooseneck height is between 1350mm-1500mm, and the height of the load platform varies from 1250-1400mm. It is worth noting that the load platform of a low-bed trailer is not horizontal. It is a sloping surface with a height difference of around 40mm. At the rear of the low bed trailer is a foldable climbing ladder, which folds to a height of 3500-3800mm from the ground.

  • Rear dump trailer

The rear dump trailer transports loose goods such as gravel, dirt, and coal. And it consists of a semi-trailer chassis and a cargo box. When unloading, the container is lifted by a hydraulic cylinder at the front of the rear dump trailer, and the cargo is dumped out using the height difference. The height of a rear dump trailer is generally designed to be between 3300-3500mm, with 3500mm being the most common. The height of the chassis is generally 1500mm and the height of the container can be customized according to the customer’s requirements. After being lifted during unloading, the height of the container can reach 4-5 meters.

  • Sidewall dump trailer

Sidewall dump trailers are used for the transport of loose goods such as coal, gravel, and building materials. Unlike the rear dump trailer, the sidewall dump trailer is lifted by several small cylinders underneath the container. The height of the sidewall dump trailer is 2800-3350mm, of which the height of the container is generally at most 1550mm. If too high, it can easily cause an overturning accident when unloading.

  • Fence cargo trailer

The fence cargo trailer is mainly used to transport agricultural products, animals, vegetables, fruit, clothes, and electrical appliances. It is mainly composed of a chassis and a fence. The height of the chassis is 1550-1660mm, and the height of the fence varies from 1500-2700mm. The whole semi trailer height must not exceed the specified 4200mm to ensure safety.

Fuel tanker trailers are mainly used to transport and store petroleum derivatives (petrol, diesel, crude oil, lubricating oil, etc.). The fuel tanker trailer also consists of two parts – the chassis and the tank. The height of the chassis is generally 1550mm. And the height of the fuel tanker trailer is around 3500mm, not exceeding 4200mm. The height of a fuel tanker trailer is directly related to its volume, so it is usually described directly by the number of volumes, such as 45 square tanker semi-trailer and 50 square tanker semi-trailer.
