3 Axle 30CBM U Dump Trailer Detailed Description
The 6 Axle 40 Ton U-Type Dump Semi Trailer by ZW Group is engineered for high-performance bulk material transport. Constructed from thick, high-strength carbon steel, the trailer body resists abrasion from sand, coal, gravel, and ore, ensuring long-lasting durability. Its U-type design and reinforced chassis provide excellent rigidity and weight distribution, which improves handling and reduces road wear.
Equipped with a reliable HYVA hydraulic tipping system, it offers steep dumping angles for efficient and quick unloading, maximizing productivity on-site. The trailer’s heavy-duty FUWA/BPW axles and robust suspension system (mechanical or optional air suspension) guarantee stability and smooth rides over rough terrain.
Safety features include dual-line pneumatic brakes, optional ABS, and LED lighting, meeting global standards like ISO9001, CE, DOT, and CCC. The trailer also includes a JOST landing gear and kingpin for easy hitching and maneuvering.
Ideal for sand transport trailers, coal haulage, and other heavy-duty dump trailer applications, this semi trailer combines strength, safety, and reliability for demanding logistics, mining, and construction projects worldwide.
