Key Features & Advantages
✅ Easy Tire Maintenance
Three‑piece split construction allows quick disassembly, eliminating difficulties when removing heavy OTR tires. It drastically cuts downtime during tire‑replacement work at mine sites.
✅ High Load‑bearing & Impact Resistance
Made of heavy‑gauge high‑strength steel. Optimized structural design offers excellent shock‑resistance, suitable for harsh, bumpy underground and open‑pit mining working environments.
✅ Strong Anti‑corrosion Protection
Uniform red anti‑rust primer coating provides reliable temporary corrosion resistance during storage, sea transportation and on‑site operation. Extra finish paint can be customized on request.
✅ Precise Dimensional Consistency
Each segment is machined with tight tolerance. All parts match perfectly when assembled, avoiding air leakage, loose fitting or wobble after tire installation.
✅ Cost‑effective Spare‑part Solution
If one single segment gets damaged, you only need to replace the broken piece instead of the whole rim, which significantly reduces your long‑term consumable costs.
