Underground mining is one of the most demanding industries in the world. The confined spaces, rugged terrain, heavy loads, and continuous work cycles place immense stress on every piece of equipment , especially the wheels . As a critical component, underground mining wheels must possess unparalleled strength, safety, and reliability to ensure efficient operation.
the original equipment manufacturer (OEM) rim supplier for Caterpillar's underground mining equipment in China, HYWG provides high-performance rim solutions to ensure safety, efficiency, and high productivity in the most challenging environments.
HYWG rims – designed for extreme environments
Unlike open-pit mining, underground environments require equipment to operate within narrow tunnels, limiting mobility. CAT Underground mining vehicles are designed for power, reliability, and continuous operation in confined spaces. These machines require rims capable of withstanding extreme loads, sharp turns, and continuous impacts . Precision-designed underground mining rims are custom-made to CAT equipment specifications to ensure optimal fit, load capacity, and performance.
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 comprehensively outperform standard rims in terms of concentricity, fatigue resistance, weld strength, and service life. High-strength, high-quality steel ensures that the rims can meet these challenges while maintaining unaffected performance.
Improve the safety of operations in confined spaces
In underground mining , operational safety is paramount. Wheel integrity directly impacts vehicle stability and operator safety. HYWG's R&D team has designed high-quality underground mining wheels specifically for CAT vehicles , featuring a 5PC multi-piece design, reinforced flanges, a safety locking system, and precise bead seat profiles. These features reduce the risk of tire failure, ensure stability, and minimize the risk of accidents even under the most demanding working conditions.
28.00-33/3.5 is 5PC structure rim for TL tire, it’s commonly used by Underground loader and truck. Our quality of underground mining rims have been proven. We are able to supply underground mining rims for CAT, Sandvik, Atlas Copo.
Combining durability and efficiency
Downtime costs are high in underground mining. Reliable wheel solutions help reduce maintenance frequency and extend service life by improving durability and minimizing wear .
HYWG boasts a complete industrial chain from steel to finished wheel rims, encompassing steel rolling, mold design, high-precision forming, automated welding, surface treatment, and finished product inspection. This "one-stop" production model ensures that all products meet uniform high standards, truly achieving full-chain manufacturing and quality control for wheel rims.
