Traction – Building reliable OTR wheel solutions from every rim component.

For construction machinery, mining equipment, and industrial vehicles, wheel rims are not only a key component connecting the tires to the vehicle, but also an important structural part that bears the weight of the entire machine, transmits driving force, and withstands impact loads. Therefore, a set of high-performance wheel rims relies on strong manufacturing capabilities and strict quality control.

Traction has been deeply involved in the construction machinery wheel rim industry for over 30 years. Relying on a complete industrial chain manufacturing system, a professional R&D team, automated production equipment, and strict quality inspection processes, it provides global customers with professional solutions from wheel Rim Components to finished wheels.

The reliability of a high-performance Otr Rim begins with the materials, but depends even more on the manufacturing process.

Traction possesses independent production capabilities for wheel rim steel, building a complete manufacturing system from raw steel materials to finished wheel rims, enabling full-process control over product quality.

From steel profile production and forming to welding, machining, assembly, painting, and quality inspection, Traction incorporates every key step into its manufacturing system to reduce quality fluctuations caused by supply chain issues and ensure material performance, dimensional accuracy, and product consistency.

Why is it crucial to produce steel profiles in-house?

• 01｜Controlling material quality from the source: Based on the structure and operating conditions of the wheel rim products, the steel materials are strictly controlled to provide a stable and reliable foundation for subsequent manufacturing.
• 02｜Improving Dimensional Consistency: The dimensions and geometric accuracy of the steel profiles directly affect the quality of wheel rim forming and assembly. In-house production helps strengthen process control and improve product consistency.
• 03｜Optimize Product Structure: With its professional R&D and engineering team, Traction can continuously optimize the steel profile and rim structure according to different vehicles, tire specifications and operating conditions.
• 04｜End-to-end manufacturing, more efficient and controllable: From structural steel to finished wheel rims, the production process is closely integrated, which helps to improve production efficiency, shorten delivery cycle, and quickly respond to customers' customized needs.

From a single steel section to a wheel rim; from material control to final inspection. Traction integrates its full-chain manufacturing capabilities into every product, providing stable and reliable OTR rim solutions for mining trucks, wheel loaders, graders, heavy-duty forklifts, and other construction machinery.

Controlling quality from the source is a key advantage of Traction's entire industrial chain manufacturing.

By adopting automated welding, advanced equipment is combined with standardized production processes to strictly control welding parameters, welding paths, and production processes, resulting in more stable and consistent welding quality.

For construction machinery and mining vehicles that are subjected to heavy loads, impacts, and vibrations over long periods, Traction employs reasonable welding and structural control in key stress areas of the wheel rim to enhance overall connection strength, ensure good structural stability and fatigue resistance, and provide reliable support for heavy-load conditions.

Traction provides systematic management of the welding process and, in conjunction with subsequent testing, conducts quality checks on key welded areas to ensure that the product meets design requirements.

For different application scenarios such as construction machinery, mining vehicles, industrial vehicles and agricultural machinery, vehicles have different requirements for the size, structure, load-bearing capacity and operating conditions of wheel rims.

Traction, relying on a complete rim manufacturing system and rich experience in OTR rim R&D, can provide various structural forms such as 1PC, 3PC, and 5PC, covering diverse needs from small and medium-sized engineering machinery to large mining equipment. Especially for large rims of 22.00-25, 25.00-25, 27.00-29, 29.00-25, and 35 inches and above, Traction designs rims specifically for different vehicle loads, tire matching, and operating environments.

We have extensive involvement in the fields of engineering machinery, Mining Rims, forklift rims, industrial rims, agricultural rims, other rim components, and tires. The following are various sizes of wheel rims that our company can produce for different applications:

High-performance wheel rims require not only advanced manufacturing processes, but also a comprehensive quality management system.

Traction maintains strict control over key processes during production and employs multiple quality control measures, including dimensional inspection, weld inspection, structural inspection, and finished product inspection, to ensure that products meet design requirements.

Meanwhile, relying on a professional R&D and engineering team, Traction continuously optimizes product structure, analyzes operating conditions, and improves performance, thereby enhancing the reliability of wheel rims in complex environments.
