In the fields of mining, construction, and heavy engineering equipment, wheels and rims, as key load-bearing components, operate under high loads, strong impacts, and complex working conditions for extended periods. Scientific and standardized inspection and maintenance are not only directly related to equipment operating efficiency but are also a core element in ensuring operational safety.
As a professional OTR wheel and rim manufacturer, HYWG leverages its advanced manufacturing system and rigorous quality control to provide global customers with integrated solutions from product design and manufacturing to maintenance support.
In actual working conditions, the most common problems with wheel rims include cracks concentrated in the welds and rim edges , localized deformation caused by mining impacts and overloading , and surface corrosion caused in humid and salt spray environments, all of which affect work efficiency.
Since its inception , HYWG has accumulated over thirty years of manufacturing experience . Using high-quality steel produced in-house, HYWG ensures the safety limits, consistency, and long-term reliability of its wheel rims from the source, resulting in superior concentricity, fatigue resistance, weld strength, and service life compared to standard wheel rims. The factory employs automated welding processes and 100% weld flaw detection to guarantee higher structural reliability before shipment, ensuring excellent fatigue and impact resistance and reducing the failure rate.
For multi-piece (3PC / 5PC) wheel rims commonly used in mining vehicles , there may be issues such as whether the locking ring is deformed or worn , whether the retaining ring is stuck , and whether the wheel rim components fit tightly .
HYWG has a research and development team composed of senior engineers and technical experts who design suitable rims based on vehicle performance and working conditions. Through precision machining and strict tolerance control, the lock ring and rim achieve high matching and stable locking performance, significantly improving on-site safety.
HYWG uses high-precision machining equipment to ensure the smoothness of the bead seat surface and the consistency of rim dimensions , avoiding air leakage and wear on the sealing surface , thereby effectively reducing the risk of air leakage and extending tire life. The product design fully considers uniform stress distribution and a high-strength connection structure to improve the overall vehicle's operational stability.
HYWG has a complete rim production system , from steel rolling, mold design, high-precision forming, automated welding to surface treatment and finished product inspection. This "one-stop" production model ensures that all products meet the same high standards, truly realizing full-chain manufacturing and quality control of rims.

The product is optimized for mining and heavy-duty applications . For equipment such as mining trucks and loaders , it enhances the impact resistance of the rims , optimizes the structural strength of the rims , and improves wear resistance and corrosion resistance . This ensures that the product maintains stable performance even in extreme environments.
The inspection and repair of wheels and rims on construction machinery is not only part of equipment maintenance, but also a crucial guarantee for safe production. Leveraging HYWG's strong manufacturing capabilities and quality system, users not only obtain high-performance products, but also a complete rim solution covering the entire lifecycle.
In high-intensity, high-risk engineering environments, choosing a reliable rim partner means choosing safety and efficiency.
With its strong manufacturing capabilities and engineering experience, HYWG has become a leading brand in the industry, winning unanimous praise from OEM manufacturers and end users. It is an original equipment manufacturer (OEM) rim supplier in China for well-known brands such as Volvo, Caterpillar, Liebherr, and John Deere. HYWG 's products are exported to more than ten countries including North America, Europe, Australia, and Russia , making it a trusted partner for OTR ( Original Equipment Manufacturer) users worldwide .
