Traction OTR mining wheels – providing reliable load-bearing solutions for heavy-duty mining conditions worldwide.
In applications such as mining transportation, open-pit mining, and underground operations, vehicles constantly face severe challenges such as overloading, high impact, long-term continuous operation, and complex road conditions.[cite: 14]As a crucial load-bearing component connecting the tires and the vehicle, the structural strength, manufacturing precision, and reliability of OTR Mining Wheels directly affect the overall vehicle's operational safety, tire lifespan, and equipment operating efficiency.[cite: 14]
With over 30 years of experience in manufacturing engineering machinery wheels, Traction focuses on providing high-performance Otr Wheels and rim solutions for mining dump trucks, underground mining vehicles, loaders, and other heavy engineering machinery.[cite: 14]
Traction possesses a complete wheel manufacturing system, enabling full-process production and quality control from rim steel to finished wheel products.[cite: 14]

From raw material and steel production to rim rolling, forming, welding, machining, assembly, painting, and final inspection, Traction achieves autonomous control over key manufacturing processes through a complete production flow.[cite: 14]
This full-chain manufacturing model not only improves production efficiency but also reduces quality differences between different supply links, ensuring consistent product size, material properties, and manufacturing quality, thus providing a reliable wheel base for large mining vehicles.[cite: 14]
The working environment of mining vehicles is far more demanding than that of ordinary construction machinery.[cite: 14]
Vehicles may need to operate for extended periods on gravel, mud, slopes, and rugged mining roads, while bearing the combined loads of their own weight, loads, and frequent braking, steering, and road impacts.[cite: 14]
For different vehicle models, tire specifications, and operating conditions, the Traction R&D and engineering team continuously designs rim structures, optimizes dimensions, and improves product performance.[cite: 14] Based on the actual needs of vehicles, they develop multi-piece OTR rims of different specifications, such as 1PC, 3PC, and 5PC, to provide matching wheel solutions for different types of mining equipment.[cite: 14]
For large OTR wheels, the manufacturing process directly affects the product's performance.[cite: 14]
Traction employs mature production processes and automated manufacturing equipment, strictly controlling key production stages.[cite: 14] Particularly in the rim forming and welding processes, standardized process control ensures stable dimensional accuracy and excellent structural consistency in the products.[cite: 14]
Meanwhile, Traction emphasizes welding quality control, reducing quality fluctuations during the manufacturing process through professional welding equipment, process parameter control, and quality inspection, thus providing a reliable structural foundation for mining wheels to withstand high loads over long periods.[cite: 14]
Mining wheels need to withstand long-term, high-intensity actual working tests, so product quality inspection is an important part of the Traction manufacturing process.[cite: 14]
From raw materials to finished products, Traction implements strict quality control over key production processes and conducts comprehensive testing on finished products, including dimensions, appearance, welding quality, and related performance.[cite: 14]

Through a comprehensive quality management system and testing procedures, we ensure that every wheel leaving the factory meets the corresponding design and quality requirements, providing customers with stable and reliable products.[cite: 14]
Mining vehicles operate under complex conditions and bear high loads, placing higher demands on the load-bearing capacity, structural strength, and efficiency of disassembly and maintenance of wheels.[cite: 14] Traction provides comprehensive multi-piece OTR rim solutions for different tonnages, vehicle types, and tire specifications.[cite: 14]
- 3PC rims: Balancing load-bearing capacity with ease of assembly and disassembly, suitable for medium and heavy-duty equipment such as loaders and underground mining vehicles.[cite: 14]
- 5PC rims: Designed for large mining dump trucks and heavy-duty construction machinery, providing a stable and reliable mounting and load-bearing foundation for large tires.[cite: 14]
- Multiple specifications available: can be matched according to different vehicle loads, tire sizes and operating environments to meet diverse mining application needs.[cite: 14]
- Reliable structural design: Through reasonable rim structure, manufacturing process and strict quality inspection, the reliability of the product under high load and strong impact conditions is improved.[cite: 14]
Leveraging Traction's full-chain manufacturing capabilities, from rim steel to finished wheels, as well as its mature R&D, welding, processing, and testing systems, Traction continuously provides mining vehicles with high-performance, multi-specification, reliable, and durable OTR rim solutions.[cite: 14]
