The RTH18 Open Top Wagon is a heavy‑capacity, versatile rail freight wagon specially developed for bulk and general cargo transport. With its high‑strength steel structure, light deadweight, and large loading volume, this wagon is widely used in bulk cargo logistics, mining, construction, metallurgy, and forestry industries. It fully meets the requirements of 10,000‑ton heavy‑haul train operations, delivering high efficiency, reliability, and economy for modern rail transportation.

The RTH18 open top wagon provides strong versatility for various cargo types, including coal, ore, building materials, machinery, steel products, and timber. It supports both manual unloading and mechanical unloading with tippers, making it suitable for diverse freight stations and logistics scenarios.

Its structure adopts 450 MPa high‑strength steel, ensuring excellent rigidity and fatigue resistance. The lightweight design concept reduces tare weight to 23 t while achieving a 61 t load capacity and 73.3 m³ volume capacity, greatly improving transport efficiency.

The wagon is fully compatible with 10,000‑ton heavy‑haul train transportation, enabling stable and safe operation under heavy‑load working conditions. Reasonable dimensions and axle load distribution ensure stable running, low energy consumption, and long service life.
