Dongxu 2-axle 3-axle shipping container transport trailer semi-trailer

1. Definition and structure

A container frame transport trailer is a semi-trailer specially used for transporting containers. It is mainly composed of frame, outriggers, suspension system, axle and connecting device. The connecting device is usually a traction pin installed on the front end of the frame, which is used to connect with the tractor to ensure that the trailer can stably follow the tractor during transportation.

2. Dimensions

Can produce standard lengths such as 20 feet, 40 feet, 45 feet, 50 feet, 53 feet, etc. The width is 2.5 meters. This width is to adapt to the width of international standard containers and comply with traffic regulations when driving on the road, ensuring the stability and safety of the vehicle.

3. Carrying capacity

The load-bearing capacity of a container frame transport trailer mainly depends on factors such as the number of axles, frame structure, and tire specifications. There are different configurations such as 2-axis, 3-axis, etc. A 2-axle skeletal trailer has a relatively low load capacity and can typically carry a 20-foot or 40-foot container with a lighter gross mass, with a maximum gross mass of around 30 - 40 tons. The 3-axle skeleton trailer has a strong carrying capacity and can carry heavier containers of more than 40 feet or two 20-foot containers, and the maximum total mass can reach 40-50 tons.

4. Suspension and axles

The suspension system is crucial to ensure the smoothness and comfort of the vehicle. Common suspension systems include leaf spring suspension and air suspension. Leaf spring suspension has a simple structure, strong load-bearing capacity and low cost. It uses multiple layers of leaf springs to buffer the vibrations during vehicle driving. Air suspension has better shock absorption and adjustability

5. Applicable scenarios and advantages

Mainly in the fields of ports, logistics parks and road transportation, its advantage lies in its strong versatility and ability to adapt to various standard containers, including ordinary dry cargo containers, refrigerated containers, etc. Due to its "skeleton" structure, its own weight is relatively light, and it can transport more goods while meeting the load-bearing requirements, improving transportation efficiency and reducing transportation costs.
