8.50-20/1.7 rim for Mining rim Underground Mining Universal
Underground Mining：
8.50-20/1.7 is a widely used rim specification for engineering machinery in underground mining vehicles, primarily used in underground mining transport vehicles, underground loaders (LHDs), underground service vehicles, and underground auxiliary equipment. This specification balances load-bearing capacity, impact resistance, and adaptability to complex underground working conditions, making it one of the common small to medium-sized OTR rims for underground mining equipment.
The moderate rim width provides good tread support, more stable tire mounting, better load distribution, and stronger adaptability to various working conditions.
20 indicates a rim diameter of 20 inches.
20-inch rims are very common in underground mining equipment, suitable for small to medium-sized underground transport equipment, vehicles in narrow tunnels, and low-profile mining equipment.
Their advantages include compact structure, flexible steering, better suitability for low-depth tunnels, and improved maneuverability.
1.7 indicates the rim flange thickness and structural grade.
The 1.7 structure is typically used in heavy-duty engineering machinery, underground mining vehicles, and high-impact applications. Featuring higher flange strength, enhanced impact resistance, and longer fatigue life, the HYWG 8.50-20/1.7 rim is particularly suitable for complex rocky environments underground.
The HYWG 8.50-20/1.7 rim boasts superior impact resistance, utilizing high-strength rim-specific steel produced in-house. From the material source, the safety and lifespan of the OTR rim are determined. This results in superior concentricity, fatigue resistance, weld strength, and service life compared to standard rims. High-strength, high-quality steel ensures excellent fatigue and impact resistance.
It is ideal for continuous, high-intensity operations in underground mines.
Underground mining vehicles typically require low-profile designs, small turning radii, and greater maneuverability. The 20-inch rim helps lower the overall height of the equipment, improves tunnel clearance, and enhances steering flexibility.
The 8.50-20/1.7 rim provides stable support for mining engineering tires, reducing abnormal tire deformation, improving heavy-load stability, reducing roll risk, and enhancing underground transportation safety. Its effectiveness is particularly evident in working conditions such as slippery roadways, ramp transport, and heavy-load turns.
The underground mining environment places extremely high demands on rim corrosion and fatigue resistance. HYWG has a complete product coating line that effectively enhances corrosion resistance, fatigue resistance, and service life, reducing the frequency of maintenance for underground equipment.
