In the global mining and heavy construction machinery industry, the reliable operation of equipment highly depends on the core load-bearing component—the wheel system. As a representative model of large wheel loaders, the Volvo L220H has long served in mining loading, aggregate transportation, and high-intensity engineering operations, placing extremely high demands on the safety and durability of its wheel system. The equipment requires frequent loading, transporting, and unloading; the wheel system not only bears the weight of the entire machine but also needs to withstand impact loads from the ground and fatigue stresses generated by continuous operation.
Leveraging its globally leading engineering machinery wheel manufacturing system, HYWG provides Volvo L220H with a 25.00-25/3.5 5PC large OTR rim solution. With its strong factory capabilities and industry authority, HYWG provides a stable and safe operating foundation for the equipment.
25.00-25/3.5 is a 5PC structure rim for TL tires, commonly used in articulated trucks. HYWG is an original equipment manufacturer (OEM) rim supplier for Volvo, Caterpillar, Liebherr, John Deere, and Doosan in China.
HYWG 25.00-25/3.5 5PC rims are designed specifically for large OTR (over-the-counter) applications.
1. Excellent load-bearing capacity, capable of handling extreme heavy-load environments.
The 25.00-25/3.5 large wheel rim adopts a high-strength structural design, which can effectively distribute the load pressure during vehicle operation and provide stable support for the Volvo L220H.
Whether on mine slopes, rugged roads, or in high-load loading cycles, HYWG rims maintain excellent structural stability, helping equipment achieve continuous and efficient operation.
2. The 5-piece multi-unit structure improves reliability and maintenance efficiency.
Compared to ordinary rims, the 5PC multi-piece rim structure is more suitable for large-scale engineering machinery applications:
• Optimize the fit between the rim and the tire;
• Improve tire installation stability;
• Facilitates on-site disassembly and maintenance;
• Reduce equipment downtime.
For mines and large-scale engineering projects, reliable maintenance efficiency means higher equipment utilization and lower operating costs.
3. Enhanced impact resistance to adapt to complex working conditions.
Large loaders often operate in complex environments such as gravel, ore, and mud, and the wheel rims need to withstand the impact and vibration from the road surface as well as the pressure from frequent turning.
HYWG enhances the fatigue resistance of wheel rims through advanced manufacturing processes and rigorous quality testing, enabling them to meet the demands of long-term, high-intensity operations.
Globalized Manufacturing System – HYWG's Core Competitiveness
As one of the world's top three OTR (Off-The-Road) wheel and rim manufacturers, with over 30 years of manufacturing experience , HYWG has established a global industrial layout for engineering machinery wheels, forming a full-chain capability from R&D, manufacturing to delivery.
● Independent manufacturing capabilities across the entire industry chain
HYWG possesses the capability to independently produce rim-grade steel, determining the safety limits, consistency, and long-term reliability of rims from the source. This results in products that are superior to ordinary standard rims in terms of concentricity, fatigue resistance, weld strength, and service life. High-strength, high-quality steel ensures that the rims exhibit excellent fatigue and impact resistance.
It possesses a complete industrial chain from steel to finished wheel rims, including steel rolling, mold design, high-precision forming, automated welding, surface treatment, and full-process product testing . This "one-stop" production model ensures that all products meet uniform high standards, truly realizing full-chain manufacturing and quality control of wheel rims.
