This 3‑axle enclosed box semi‑trailer adopts heavy‑duty high‑strength steel structure, fully‑enclosed hard side box body with multi‑groups side doors for easy loading and unloading. Fully rain‑proof and dust‑proof design, ideal for general dry cargo, grain, hardware, industrial supplies and other goods requiring weather protection.
Different from ordinary flatbed semi‑trailers, multiple side swing doors enable fast side loading/unloading without only relying on rear doors. Robust undercarriage, heavy‑load axles and durable tires ensure stable performance under long‑distance and heavy‑haul transportation scenarios. Customization on body length, height, door quantity and painting color is available to match various regional transport regulations.
Built with heavy‑duty Q355 high‑strength steel, this 3‑axle enclosed box semi‑trailer features a fully‑closed cargo box with multiple side swing doors and rear double doors. It enables flexible loading and unloading from both side and rear positions. Rain‑proof and dust‑proof performance protects general dry cargo, grain and bag‑type goods during long‑distance highway transportation. All key components are durable for heavy‑load operation, while dimensions, door layout and paint color support full customization to meet different market requirements.
