Chassis structure and composition

Chassis trucks are specialized vehicles developed from land trailer transport. Their steel frame structure can be adapted to the needs of standard and special container transport. Based on the loading and unloading methods and functional differences, they are mainly divided into three types: tilting, ordinary and retractable. The tilting chassis truck uses a hydraulic system to achieve rapid loading and unloading of granular materials . As of February 2023, the industry faces the dual pressures of production stagnation and freight volume surge caused by the global microchip shortage. Chassis truck storage operations use a co-storage mode of containers and special chassis trucks. During transportation, they need to be precisely aligned with corner pieces and twist locks to ensure safety. Structure and composition Chassis trucks use high-strength steel welded frames as the main load-bearing structure, equipped with a two-axle or three-axle frame system to support the container load. The suspension system generally uses rubber torsion shafts or coil spring devices to effectively absorb road impact during transportation. The braking system is linked to the tractor and equipped with a pneumatic brake device to achieve synchronous response [2]. Modern models integrate GPS tracking modules, tire pressure monitoring sensors and LED marker lights to improve transportation visualization and safety.
