Products Description
This high strength underground mining LHD wheel rim is manufactured by Anqiang, specially built for underground load-haul-dump mining vehicles. Underground tunnels have narrow space, sharp rock fragments, uneven ground, frequent start-stop and heavy impact load. Ordinary rims crack or deform easily in such conditions. Our LHD rim adopts low alloy high strength steel and optimized multi-piece structure, stable bead locking, to reduce onsite breakdown and cut maintenance cost for underground mining fleets.
Key Features
- 3-piece / 5-piece split structure, easy tire mounting and onsite maintenance in underground tunnel
- CNC machined bolt holes, chamfer treatment, reduce stress concentration, avoid bolt hole cracking under repeated vibration
- Reinforced rim flange and lock ring groove, prevent tire slipping or bead dislodging under heavy hauling
- Sandblasting + anti-rust primer + heavy-duty topcoat, suitable for damp, dusty underground mine environment

Important Notes (Onsite Safety & Operation)
- Check rim, lock ring, side ring for crack, dent, deformation before every tire assembly. Do NOT use damaged parts.
- All assembly parts must be from one matched set; do not mix lock rings or rim components from different batches or suppliers.
- Clean rust, rock grit and burrs on bead seat and lock groove before tire installation. Foreign objects will cause lock ring failure.
- Must use inflation safety cage when inflating tires. Never stand in front of rim during inflation.
- Tighten wheel bolts in cross sequence with torque wrench, follow the torque value of your LHD machine manual. Recheck torque after first 20 hours operation underground.
- Do not weld, heat or hammer on the rim in working site. Welding will destroy material strength and cause sudden rim failure.
- Regular inspection cycle: check rim and lock ring every 150 working hours in underground mines. Stop use once crack, permanent deformation or loose locking is found.
- Store spare rims in dry place, avoid long-term stacking in damp tunnel area to prevent heavy corrosion.
