What is a mining wheel?

Mining wheels are heavy-duty wheel systems specifically designed for mining equipment to operate under extreme conditions. They are an indispensable core component of mining transportation and operation equipment.

Mining wheels are wheel assemblies used in both open-pit and underground mining equipment, serving vehicles such as mining dump trucks , underground scrapers , underground mining cars, wheel loaders, and mining graders . They are capable of bearing huge tonnage , resisting strong impacts and cutting , and adapting to extremely harsh working conditions to achieve long-term stable operation .

Unlike ordinary road vehicle wheels, mining wheels need to withstand complex and harsh environments such as high loads, strong impacts, sharp gravel, high temperatures, mud, and steep slopes for extended periods. Therefore, they require more stringent structural design, material selection, and manufacturing processes.

A complete mining wheel typically consists of a mining rim, mining tires, and safety structures such as lock rings and sealing components. The rim, as the load-bearing core, must be made of high-strength steel and have excellent resistance to deformation and fatigue to prevent cracking or failure under continuous heavy loads and repeated impacts.

We are one of the world's top three OTR wheel manufacturers, and our products serve extreme working conditions in mines, ports, and construction sites worldwide .

The primary function of mining wheels is to provide stable support and traction for equipment, ensuring safe vehicle operation in complex mining terrain. They also directly impact equipment efficiency and operating costs. Inadequate mining wheel performance can lead to premature tire damage, rim deformation, equipment downtime, and even safety accidents, thereby increasing maintenance costs and affecting production schedules.

Depending on their structural form, mining wheels can be divided into one-piece rims and multi-piece rims. Multi-piece rims are widely used in large mining equipment because they are easy to disassemble and maintain.

With over two decades of dedicated experience, HYWG has served hundreds of OEMs worldwide, designing and manufacturing high-quality rims for various off-highway vehicles. Boasting a research and development team comprised of senior engineers and technical experts, HYWG focuses on the research and application of innovative technologies, maintaining a leading position in the industry. The company's products are widely used in large construction machinery such as mining dump trucks, wheel loaders, graders, and articulated trucks , maintaining stable performance under extreme high loads, impacts, and harsh road conditions.

As Volvo 's original equipment manufacturer (OEM) wheel rim supplier in China , we have custom-designed high-strength professional wheel rims — 22.00-25/3.0 — for the Volvo L120H wheel loader , comprehensively improving the equipment's overall performance in mines, quarries, and heavy-duty conditions.
