Features of 40ft High Sidewall Trailer
High Sidewall Design for Maximum Load Volume
With a 2000mm high sidewall structure, this trailer allows operators to load more cargo per trip. It is especially suitable for loose, bagged, or palletized goods, reducing the need for additional securing equipment and improving loading efficiency.
Heavy-Duty Chassis and Reinforced Floor
The trailer features a reinforced steel chassis combined with a 3mm thick steel loading floor. This structure ensures excellent resistance to deformation under heavy loads, making it ideal for long-term use in rough road and high-frequency transport conditions.
Stable 3-Axle Configuration for Heavy Loads
Equipped with three 13-ton axles and a spring suspension system with 8 leaf springs, the trailer delivers stable load distribution and reliable braking performance, even when fully loaded. This setup improves driving safety and extends axle and tire service life.

As a direct manufacturer, we offer customization options including sidewall height, axle brands, suspension types, braking systems, and color selection. Each trailer is produced under strict quality control to ensure consistent performance and durability.
