3-Axle Shipping Containers 12R22.5 Tyre Skeleton Semi-trailer

1. Chassis structure
Skeleton design: Welded with high-strength steel, strong structure and light weight, to ensure load capacity while reducing self-weight.

Beams and longitudinal beams: The criss-cross beam structure provides stable support for the fixing and transportation of containers.

Low center of gravity design: reduce the center of gravity of the vehicle, improve driving stability, especially suitable for high-speed long-distance transportation.

2. Securing the container
Twist lock system: The twist lock installed at the four corners of the frame car is used to secure the container, ensuring that the container will not move or fall off during transportation.

Adjustment function: The twist lock can be adjusted according to the container size (such as 20 feet or 40 feet) to adapt to different specifications of containers.

Anti-slip device: Some skeleton vehicles are equipped with anti-slip pads or anti-skateboards to increase the friction between the container and the frame and prevent sliding.

.

3. Suspension system
Air suspension: Some high-end skeleton cars use air suspension system, which can adjust the height of the body to adapt to different road conditions and loading and unloading needs, while reducing cargo vibration.

Leaf spring suspension: economical and practical, suitable for general freight needs, strong carrying capacity.

4. Axle and tires
Single-axle or two-axle design: Depending on the load requirements, the frame car can be equipped with single, two-axle or even three-axle.

Wide tire design: Larger tire width, increase the contact area, improve the carrying capacity and driving stability.

Tire pressure monitoring: Some models are equipped with tire pressure monitoring system to monitor tire status in real time to ensure driving safety.

5. Connection with traction device
Traction pin: used to connect with the tractor (front) to ensure stable traction.

Electrical interface: Connect the light, brake and other electrical systems of the tractor and the skeleton car to ensure signal synchronization.

Brake system: Equipped with pneumatic brake or electronic brake system to improve braking performance.
