Semi trailer for transporting materials

The semi-trailer for transporting timber and steel is a special semi-trailer designed specifically for the transportation of goods of equal length. Its frame adopts a low-alloy steel welded frame structure, which is rigidly connected to the tractor through traction pins. The rear layout of the axle ensures that the weight of the goods is transmitted to the tractor chassis through the traction pins, achieving balanced load distribution. This model is equipped with a three-axis balanced suspension system, and the front and rear steel plate springs are adjusted through mass balance blocks, which can adapt to the transportation needs of 30 ton wood in rough road conditions. The deflection change of the frame is controlled within ± 5mm, ensuring driving stability.

The carriage adopts a detachable flat plate or warehouse grid structure, with an effective length covering a range of 12-14 meters. The height of the cargo platform above the ground is less than 1.2 meters, and with the help of a hydraulic lifting device, it can achieve rapid loading and unloading in 45 seconds. The core components are made of high-strength wear-resistant steel plates, which reduce the weight by 25% compared to traditional vehicle models, and increase the single transportation efficiency to over 28 tons, especially suitable for medium and long-distance trunk transportation from forest logging sites to processing plants. In terms of safety design, it integrates LED lighting warning system and dual circuit pneumatic braking. The pressure holding time of the hill parking brake is ≥ 10 minutes, which meets the requirements of working on a 35 ° slope in mountainous areas.
