Types of Skeletal Trailer
The skeletal trailers produced by our company mainly include the following types:
Tri Axle Container Chassis
A three - axle container chassis possesses distinct characteristics and numerous advantages, making it a preferred choice in the field of container transportation. The three - axle design provides a stable and robust load - bearing structure.
2 Axle Container Chassis
The two - axle design gives the trailer a relatively compact structure. It is mainly composed of a strong steel frame that can firmly support the 40 - foot container. Despite its simplicity, the structure is robust enough to handle the weight of the container.

Key Features of Skeleton Trailers
Modular Chassis Design
Some skeleton trailers are modular, allowing sections of the trailer to be adjusted or extended to accommodate oversized or irregularly shaped cargo. This versatility is beneficial for transporting non-standard loads.
01
Telescopic Twisted Locks
Advanced models may feature telescopic twist locks that can adjust to different container heights automatically. This will ensure that containers are sticked and secured to their place effortlessly.
02
Multi-Axle Configurations
Advanced skeleton trailers for sale offer multiple axle configurations, including tri-axle or even quad-axle setups. These configurations distribute weight more evenly and enhance the trailer’s ability to carry heavy loads without exceeding respective weight limits.
03
Foldable or Retractable Rear End
Certain skeleton trailers feature a folding or retractable rear end. This design allows the trailer to extend its length when necessary for transporting longer containers while maintaining manoeuvrability.
04
Air Suspension
Skeleton trailers are equipped with air suspension systems, which provide a smoother ride and better load stability, especially over uneven terrain. This feature helps to reduce wear and tear on the trailer and even a container.

Uses of Skeleton Trailers

Intermodal Transportation
One of the primary uses of skeleton trailers is facilitating intermodal transport. They are designed to efficiently transfer shipping containers between different modes of transportation, such as ships, trains, and trucks.
Heavy-duty Container Handling
Another key use of skeleton trailers is their ability to handle size-varied shipping containers efficiently. Their structural integrity and weight-bearing capacity of over 4500 kg make them suitable for all cargos.
Long-haul Transportation
Uses of skeleton trailers include their application in long-distance transportation routes, where they efficiently carry containers over highways and freeways between cities and regions. This factor also continues to save cost and improves overall logistic operations.
Dimensions of Skeletal Trailer
12ft
The 12ft skeleton trailer is a robust-framed skeleton designed to carry a 12ft intermodal shipping container. Being a 12ft trailer, it is considerably smaller in size, and therefore easier to handle in a tight space, such as ports, warehouses, and even areas in the heart of towns.
40ft
The 40ft skeleton trailer is engineered to transport ISO-standard containers, accommodating either two 20ft containers or one 40ft container. Constructed from high-strength materials like Q345 or SM490 steel, it ensures exceptional durability and offers a payload capacity often exceeding 30 tons. Key features include multiple twist locks for secure container fastening, dual or tri-axle configurations for heavy loads, and advanced braking systems for enhanced safety. Widely used in intermodal transport, the 40ft skeleton trailer facilitates the seamless transfer of goods across ships, trucks, and trains.
45ft
The 45ft skeleton trailer is designed for transporting 45-foot shipping containers, commonly used in intermodal transportation. Its open, skeletal frame minimizes weight while providing the strength to support large containers, making it ideal for efficient loading and unloading, especially with cranes or forklifts. The trailer’s twist-lock mechanisms securely fasten containers, and its versatility allows it to accommodate different container sizes, making it a cost-effective solution for long-distance logistics across highways, railways, and ports.
1. When connecting, the trailer skateboard must be at the same level as the towing seat panel or slightly lower (up to 50mm) than the towing seat panel. A word of warning here, if you are using air suspension, the height should be slightly higher. The air suspension is softer and filled with air. If there is cargo on top of the trailer, the air will be compressed, and the height will be lower than usual.
2. When the tractor seat is in the pre-hung state (that is, the handle is pulled out), slowly drive the truck under the semi-trailer. The locking mechanism will automatically close, the handle of the tractor seat will return, and the dial will be in the return position. After the connection is complete, move the tractor slightly forward to check if the trailer hookup is good.
3.After the connection is completed, check and confirm that the locking mechanism of the tractor seat is locked before driving the truck.


1. Check whether the tractor and the semi-trailer match before connecting. If the bottom surface of the semi-trailer's traction pin plate is not suitable for the height of the plane center of the towing seat body, it cannot be connected. At the same time, pay attention to the container's oncoming surface distance. Prevent collision between the front face of the container and the tractor when the train turns.
2. When connecting, please note that the bottom surface of the semi-trailer traction pin plate is 1-30mm lower than the center of the upper surface of the traction seat body. Make sure that the separation joystick is in the separated state. The longitudinal symmetry plane of the tractor and semi-trailer should be consistent, and the deviation should be less than 40mm.
3. After connecting, check the position of the lock block carefully to prevent the lock block from bounce off when driving. The span hose joint that connects the semi-trailer and the tractor needs to be connected to the brake pipeline of the train, and check the pressure of each part Whether it meets the specified value. Connect the circuit of the semi-trailer and the tractor to ensure that the various signals of the semi-trailer work normally.
4. Separate the electrical connector and the jumper hose joint before unhooking. Make sure that the semi-trailer is parked reliably, and then shake the outrigger handle to make the outrigger fall to the ground, and raise the semi-trailer tire by 20-500mm for traction. The car slowly left the semi-trailer.
