Detailed Description
Designed for the most demanding road conditions, this 4 Axle Side Wall Semi Trailer utilizes a reinforced main beam structure made from premium Q345B high-tensile steel. The additional fourth axle significantly distributes the gross weight, allowing for a massive 70,000 kg payload while minimizing tire wear and adhering to stricter axle load regulations. As a multi-purpose general cargo truck trailer, it features durable mechanical suspension and a 3mm diamond plate floor that prevents cargo slippage, ensuring your goods arrive safely every time.
User-centric design is at the heart of this vehicle. The sidewalls are fully detachable, transforming the unit into a flatbed for oversized loads instantly. We offer extensive customization options, including 600mm to 800mm wall heights and container twist locks, making it a dual-purpose solution for both bulk cargo and container transport. Whether you call it a high side trailer or a sideboard trailer, its corrosion-resistant polyurethane paint and heavy-duty landing gear guarantee a long service life and high resale value.
