HYWG – A full-chain manufacturer, creating high-performance OTR engineering solutions.

In off-highway applications such as construction machinery, mining equipment, agricultural machinery, industrial vehicles, and forklifts, wheels and rims not only bear the weight of the entire machine, but also directly affect the vehicle's load-bearing capacity, operational stability, and operational safety.

Faced with high loads, long-term continuous operation, complex road conditions and harsh working environments, wheel rims need to have higher structural strength, better dimensional consistency and more stable performance.

HYWG leverages its complete industrial chain manufacturing system, incorporating key processes such as rim profile steel production, rim manufacturing, automated welding, surface treatment, and quality inspection into its independent production system, providing global customers with professional, high-performance OTR wheel and rim engineering solutions.

From steel profiles to finished wheel rims, the entire process is under our independent control.

Unlike traditional wheel rim production methods, HYWG has the capability to independently produce wheel rim profiles.

HYWG's "one-stop" production model, starting from raw materials and structural steel, encompasses steel rolling, mold design, high-precision forming, automated welding, surface treatment, and finished product inspection. This ensures that all products meet consistent high standards, truly achieving end-to-end manufacturing and quality control for wheel rims.

The core advantage of manufacturing across the entire industry chain lies in its stronger control over product quality and production processes.

By independently producing key steel materials, HYWG can control material specifications, dimensional accuracy, and production quality from the source, and conduct targeted product development based on different rim structures and application conditions.

This transforms the wheel rim from a separately manufactured component into an engineered product that undergoes systematic optimization in terms of materials, structural design, and manufacturing processes.

Professional R&D to meet the needs of different OTR operating conditions

Different vehicles have different requirements for wheel rims.

Mining dump trucks need to withstand huge loads and continuous impacts; wheel loaders need to perform frequent loading and unloading operations in complex construction environments; graders need to maintain stable operating performance; and forklifts and industrial vehicles pay more attention to reliability under high-load conditions.

For different application scenarios, HYWG has a professional R&D and engineering team to design and optimize products based on vehicle models, tire specifications, load requirements and actual working environments.

HYWG offers the following:

• 1PC one-piece rim
• 3PC three-piece rim
• 5PC five-piece rim
• Large OTR multi-piece rims
• Wheel assemblies for construction machinery and mining vehicles

By employing different structural designs and manufacturing processes, we provide customers with wheel solutions that better match the overall machine requirements.

Automated production improves product consistency

For OTR rims, dimensional accuracy and structural consistency directly affect tire installation, vehicle operation, and long-term performance.

HYWG applies automated equipment to several key stages of rim production, reducing human error through standardized production processes.

Especially in the processes of rim forming, welding, and processing of key components, automated equipment can help achieve more stable processing parameters and production accuracy.

A stable manufacturing process is an important foundation for stable product quality.

By continuously optimizing its production processes, HYWG is committed to ensuring that every wheel rim maintains consistent dimensions, structure, and manufacturing quality.

Superior welding process enhances the reliability of the wheel rim structure.

Welding is one of the key processes in the manufacturing of multi-piece OTR rims.

In actual use, wheel rims need to withstand vehicle weight, tire load, road impact, and dynamic loads generated by continuous operation. Therefore, the stability of the welded area is crucial to the entire wheel rim structure.

HYWG employs specialized welding processes, combined with automated welding equipment and strict process control, to systematically manage critical welding areas.

From controlling welding parameters to inspecting weld quality, HYWG integrates quality control throughout the entire production process. More consistent weld quality provides a reliable foundation for long-term load-bearing and operation under complex conditions.

Rigorous quality testing ensures that every wheel rim withstands the test.

HYWG integrates quality control into every stage from raw materials to finished products, conducting rigorous checks on the dimensions, appearance, welding, and related performance of its products.

Depending on the specific product and application requirements, corresponding product performance verification and testing can also be conducted.

Through comprehensive quality management, we ensure that our products meet design requirements and customer standards, providing more reliable wheel rim products for construction machinery and industrial vehicles.

From material control to manufacturing processes and finished product inspection, HYWG ensures quality throughout the entire product lifecycle.

With a complete manufacturing system and extensive product experience, HYWG's OTR wheels and rims can be widely used in many fields.
