Heavy-duty, precision-engineered rims engineered for major mining trucks in Brazil.
Brazil is one of the pillars of the global mineral economy, driven by immense reserves of iron ore, bauxite, manganese, and gold. While the actual extraction mines are concentrated in regions like the Iron Quadrangle of Minas Gerais, Carajás in Pará, and sectors of Goiás, the state of São Paulo acts as the unmatched financial center, logistical distribution nexus, and heavy engineering capital of South America.
The operating environment in Brazilian open-pit mines demands exceptional equipment durability. Mining dump trucks (such as the Caterpillar 777, Komatsu 930E, and heavy-duty Belaz systems) operate continuously in tropical environments characterized by high humidity, abrasive red clay soils, and severe monsoon-induced operational risks. Rims that hold giant OTR tyres are subject to massive structural stresses. A structural failure not only halts production but also presents severe safety risks for operator teams. Therefore, OTR rims utilized in the São Paulo logistics and mining supply corridors require strict manufacturing certifications, robust corrosion-resistant surface coatings, and precise structural tolerances.
The worldwide mining industry is consistently shifting towards ultra-class haul trucks to optimize cost-per-ton logistics. These massive dumpers rely on large diameter OTR tires (ranging from 49 to 63 inches). Consequently, rim engineering has transitioned from simple, single-piece fabrications into multi-piece assemblies (3-piece and 5-piece configurations) that utilize high-tensile forged steel and complex locking ring systems to secure huge tires safely.
A typical 5-piece mining rim includes a rim base, bead seat band, lock ring, and two side flanges. Under extreme payloads exceeding 300 metric tons, the lateral pressure on the side flanges is intense. Rims must be manufactured using high-quality steel alloys with zero internal structural defects. Precise CNC machining of the lock ring groove and tire-seating profiles is critical to prevent air leakage in tubeless tires, radial slip, or catastrophic flange release.

Shandong DrivePro Auto Co., Ltd. is a leading manufacturer and global supplier of high-end industrial wheel rims, with our state-of-the-art production base in Dongying City, Shandong Province, China. Established in 2016, our engineering teams are dedicated to the research, development, custom manufacturing, and global export of steel and aluminum alloy wheel rims for heavy industry, mining, agriculture, and construction.
Operating under our premier registered brand "RICHRISE", we export a catalog of over 1,000 unique wheel configurations. Our factories produce over 3 million wheel units annually. We utilize fully integrated manufacturing capabilities, ranging from engineering design and advanced material testing to tooling fabrication, precision CNC machining, and automated protective coating lines.
In terms of quality management, DrivePro holds complete system certifications, including IATF 16949, European TÜV, US DOT, and Brazil's INMETRO. This ensures full compliance with local regulatory requirements for mining operations in São Paulo and other Brazilian mining corridors.
Every single OTR rim manufactured under the "RICHRISE" brand goes through a strict sequence of engineering and testing operations to guarantee zero defect delivery.
For heavy industry logistics operations in São Paulo, importing OTR rims from specialized Chinese manufacturers like DrivePro offers significant strategic advantages:
These benefits allow Brazilian procurement managers to reduce spare parts storage costs and overall capital expenditure while keeping high-capacity haul truck fleets running efficiently in the field.
Advanced structural engineering designed for harsh operating environments.
The iron ore quarries in the Minas Gerais and Carajás sectors feature highly abrasive hematite soils. During the rainy season, acid water pools form inside mine pits. Operating heavy haul trucks in these environments exposes rims to severe chemical and mechanical wear.
Under these operating conditions, unprotected steel rims can develop pitting corrosion. Over time, these pits act as stress concentrators, which can lead to fatigue cracking along the gutter section of the rim. Additionally, mounting and dismounting heavy OTR tires can scrape off standard paint layers, exposing bare metal to oxidation.
Furthermore, our engineering teams recommend using bead-to-flange lubricants and regular inspections of the lock ring channels to clear out compacted iron ore fines. This practice ensures proper mechanical component seating, helping prevent tire slipping or pressure loss during heavy hauling.
