The underground mining environment places extremely high demands on equipment reliability. Narrow tunnels, complex road conditions, high-intensity continuous operation, and enormous load impacts necessitate that underground mining vehicles rely on high-performance, highly durable components to ensure operational efficiency. Among these components, the wheel rim, as a crucial load-bearing part between the tire and the vehicle, directly affects the safety, stability, and service life of the equipment.
a leading global supplier of OTR wheels and rims solutions, HYWG has deep expertise in the entire OTR heavy-duty rim industry chain . HYWG has developed ultra-high strength three-piece large mining wheel rims (22.00-25/3.0) specifically for underground mining conditions, designed to withstand heavy loads, harsh environments, and high-frequency operation, providing robust load-bearing support for underground mining equipment.
The 22.00-25/3.0 is a 3PC structure wheel rim from TL tires, commonly used in underground mining vehicles. We are an original equipment manufacturer (OEM) rim supplier for Volvo, Caterpillar, Liebherr, John Deere, and Doosan in China.
Designed for the harsh environment of underground mining, delivering heavy-duty and reliable performance.
Underground mining operations differ from ordinary engineering applications, requiring vehicles to operate for extended periods in environments with low lighting, high dust levels, slippery surfaces, and rugged tunnels. Mining trucks, loaders (LHDs), and underground dump trucks generate significant impact loads and lateral pressures during operation, placing higher demands on the structural strength and durability of wheel rims.
The HYWG 22.00-25/3.0 3PC rims are designed for heavy-duty use and optimized for the operating characteristics of underground mining vehicles.
1. High-strength structural design: Enhances the impact resistance of the wheel rim to meet the requirements of long-term heavy-load operation.
2. Excellent load-bearing capacity: Provides stable support for large underground mining equipment.
3. Enhanced durability: Adaptable to complex working conditions such as gravel, potholes, and slopes.
4. Stabilizes tire matching performance: Helps improve vehicle operating safety and work efficiency.
Whether in ore transportation, underground loading, or continuous handling operations, HYWG rims provide equipment with consistently reliable performance.
The 22.00-25/3.0 3PC multi-piece rim design offers several advantages .
Large underground mining vehicles typically require multi-piece OTR rims to meet the demands of heavy-duty tire mounting and high-load applications. HYWG 3PC rims offer the following features:
1. Reinforced structure to meet high load requirements.
The 22.00-25/3.0 large-size wheel rim adopts an optimized structural design to improve overall rigidity and load-bearing capacity, and can withstand the dynamic loads and impacts generated by the long-term operation of underground mining vehicles.
2. Convenient maintenance, improving equipment uptime.
The 3PC multi-piece structure facilitates tire installation, replacement, and on-site maintenance, helping to reduce downtime and improve the operating efficiency of mining equipment.
3. Precision manufacturing ensures safe operation.
HYWG uses advanced manufacturing processes to control rim dimensional accuracy, welding quality, and structural consistency, ensuring a good match between the rim and the tire and reducing the risk of abnormalities during operation.
HYWG's professional manufacturing system ensures global quality.
High-quality wheel rims rely not only on design but also on comprehensive manufacturing capabilities. HYWG has established a complete production and manufacturing system, independently developing high-strength special steels to determine the safety ceiling, consistency, long-term reliability, and safety and lifespan of OTR wheel rims from the source. This ensures that the products outperform ordinary standard wheel rims in terms of concentricity, fatigue resistance, weld strength, and service life, guaranteeing excellent fatigue and impact resistance.
The "one-stop" production model, from steel rolling, mold design, high-precision forming, automated welding to surface treatment and finished product inspection, effectively ensures that all products meet the same high standards, truly realizing full-chain manufacturing and quality control of wheel rims.
