Neuer ZW-Trailer Kofferauflieger

The ZW Group 3 Axles Cargo Box Semi Trailer is engineered with a robust, high-rigidity frame combined with a lightweight, high-strength cold-rolled steel body. It offers excellent load-bearing capacity and advanced manufacturing technology to ensure durability and safety. Featuring multiple roof styles—including closed, push-open, and open types—this trailer meets diverse transportation needs while maximizing cargo space and operational efficiency, making it an ideal choice for heavy-duty logistics and freight transport.
 
The ZW Group 3 Axles Cargo Box Semi Trailer is expertly engineered with a strong and durable structure, specifically designed to meet the rigorous demands of heavy cargo transportation. Moreover, its frame features a beam passing design, offering options for either flat or goose-neck type longitudinal beams, which ensures superior rigidity and excellent load-bearing capacity. In addition, the frame components are automatically welded and undergo shot blasting treatment, thereby enhancing corrosion resistance and significantly extending the trailer’s service life.
Furthermore, the cargo box is constructed from high-strength cold-rolled corrugated steel plates. Because it does not require additional framework, this design maximizes the internal loading space. Reinforced with X-type braces, the cargo body achieves a remarkable balance between heavy-duty load capacity and lightweight construction, which in turn improves fuel efficiency and operational effectiveness.
In addition, the trailer provides versatile roofing options, including closed roofs, push-open roofs, fully open designs, and tarpaulin pole configurations. This variety allows the trailer to be customized easily to meet specific cargo protection needs and operational preferences. Consequently, the overall design facilitates easy loading and unloading, making the trailer ideal for a wide range of freight applications—from general goods to specialized cargo—while ensuring durability, safety, and reliability throughout its lifecycle.
