Underground mines are characterized by complex environments, limited space, and harsh operating conditions, placing extremely high demands on the safety and stability of equipment. As a core load-bearing component of mining vehicles, wheel rims are particularly vulnerable; structural problems can not only affect uptime but also pose safety risks.
HYWG underground mining rims are designed for high-impact, high-load, and highly corrosive environments, offering significant advantages in strength, reliability, and durability.
HYWG possesses the advantage of independent steel profile production . This is not only a manufacturing capability, but also the foundation of quality control and safety assurance.
Unlike traditional wheel rim manufacturers that source steel from external suppliers, HYWG has the capability to independently research and develop and produce specialized wheel rim steel, enabling full-process control from steel to finished wheel rims.

This means: precisely controlling the chemical composition of steel , optimizing the matching of strength and toughness , controlling the grain structure and microstructure stability , and ensuring consistent performance of each batch of materials .
In high-risk environments like underground mines, material stability is the bottom line for safety.
Underground mining wheel rims need to be both "hard" and "tough." HYWG achieves this through source control of the steel profiles: higher bending strength , superior impact resistance , and longer fatigue life . This ensures the structure remains structurally resistant to impact and does not become brittle, and maintains stability under long-term heavy loads. Optimizing the structural cross-section and material properties enhances bending strength , impact resistance , fatigue life , and structural stability .
In underground mining operations, consistency of batch products is of paramount importance.
The advantages of independent steel production include not relying on external supply fluctuations , stable and traceable material performance , smaller batch-to-batch differences , and more controllable structural reliability .
This not only reduces the risk of sudden structural failures, but also lowers the overall operational risks of the mine.
over 30 years of manufacturing experience, HYWG boasts a research and development team composed of senior engineers and technical experts, focusing on the research and application of innovative technologies. Each rim is designed according to different working conditions. Mining rims often adopt a multi-piece structure. HYWG's advantages are reflected in the high-precision design of the locking ring , strict control of the clearance , safer on-site disassembly and assembly , and higher maintenance efficiency .
In environments with limited downhole space, a convenient and reliable structural design is particularly important.
As a globally renowned underground mining vehicle , the CAT R1600 places extremely high demands on the structural strength, safety performance, and durability of its wheel rims . Therefore, HYWG was selected as the partner wheel rim supplier .
HYWG provides professional matching 13.00-25/2.5 mining rims for CAT R1600, leveraging its high-reliability structural design and independent steel manufacturing advantages to offer safer, more stable, and more efficient support solutions for the equipment.
13.00-25/2.5 is a 5PC structure rim for TL tires, commonly used in underground mining vehicles. We are the original rim supplier for Volvo, Caterpillar, Liebherr, John Deere, Doosan in China.
The CAT R1600 is an underground mining LHD equipment that operates under high load and strong impact conditions for extended periods.
The HYWG 13.00-25/2.5 rim boasts advantages such as high structural strength, meeting the high-impact conditions of underground mining ; optimized rim cross-section design enhances deformation resistance ; load-bearing capacity matches equipment tonnage and load requirements ; and it is perfectly compatible with mainstream 13.00-25 tires . Its stable and reliable structure is the foundation for ensuring high equipment uptime.
HYWG 's biggest advantages is its self-produced rim steel . Compared to the traditional model of purchasing steel from external suppliers, self-production brings three major advantages: stable and controllable material composition , strength and toughness matched to underground impact environments , and higher quality consistency .
From raw materials to finished rims, HYWG implements end-to-end quality control to ensure that every 13.00-25/2.5 rim has reliable structural performance.
The HYWG 13.00-25/2.5 features a five-piece rim design for easy tire installation and removal , a secure and reliable locking rim structure , high maintenance efficiency , and reduced downtime .
For the CAT R1600, which operates under high-intensity, continuous conditions, high maintenance efficiency means higher productivity.
A rigorous quality system is one of the most important reasons why CAT chose HYWG . Before leaving the factory, all wheel rims undergo dimensional accuracy testing , non-destructive testing of welds , dynamic balancing and concentricity testing , and strength and structural integrity verification .
