Traction Underground Mining Rims: Load-Bearing Limits to Ensure Operational Safety
The underground mining environment is extremely harsh: narrow tunnels, high humidity, and frequent impacts from gravel and rock walls. Traction, as one of the world's top three off-highway wheel and Rim Manufacturers, withover thirty years of manufacturing experience, has quickly become the preferred supplier for many OEMs worldwide.
Traction underground mining vehicle wheel rims are made with self-produced high-strength steel and precision manufacturing processes, and are specifically designed for heavy-duty underground mining vehicles, offering the following core advantages:
- Excellent load-bearing capacity: Adaptable to heavy-duty ore transportation, ensuring the stability of the vehicle even when fully loaded.
- Impact and abrasion resistance: Resistant to impacts from gravel and rock walls, extending the life of rims and tires and reducing downtime.
- Safe and reliable: Precisely matched with mining tires to reduce the risk of slippage, wheel slippage, and rim deformation.
- Easy maintenance: The split or standardized design makes it easy to disassemble and replace the rim, reducing maintenance costs.
- Adaptable to harsh environments: Corrosion and oxidation prevention treatment ensures long-term stable operation.
Traction offers 25.00-29/3.5 large Underground Mining Rims for heavy-duty mining operations.

Traction's 25.00-29/3.5 large underground mining rim features a 5PC multi-piece design with high-strength steel, engineered for heavy-duty mining dump trucks, loaders, and heavy transport vehicles.
concact usLarge underground mining vehicles, such as mining dump trucks, loaders, and heavy transport vehicles, place extremely high demands on the load-bearing capacity and durability of wheel rims. The 25.00-29/3.5 wheel rim, with its structural design and material advantages, meets the needs of extreme mining conditions.
Traction's professional R&D team designed the 25.00-29/3.5 wheel rims specifically for the harsh working conditions of underground mining trucks. Made of high-strength steel with a 5PC multi-piece design, these rims can withstand heavy loads even when fully loaded with ore, ensuring the stability of the entire vehicle. They also support large tires, improving the vehicle's load-bearing efficiency and operational capacity.
High-strength steel combined with heat treatment effectively resists impacts from gravel, rock walls, and tunnels. It enhances the wear resistance of rims and tires, extending their service life and reducing replacement frequency.
The 25.00-29/3.5 rim precisely matches the tire flange, reducing the risk of bead slippage, wheel slippage, and rim deformation. The split-type design facilitates maintenance and improves operational safety.
Traction possesses its own steel profiles for wheel rims and a "one-stop" production model, boasting a complete industrial chain from steel to finished wheel rims. Starting from the source of materials, it determines the safety and lifespan of OTR wheel rims. This ensures that its products are superior to ordinary standard wheel rims in terms of concentricity, fatigue resistance, weld strength, and service life. High-strength, high-quality steel ensures that the wheel rims possess excellent fatigue resistance and impact resistance.
