Heavy Equipment Rims

Rim specifications: These include diameter and section width. For example, common engineering-grade wide-body rims must strictly match the original vehicle's tyre model; if the dimensions do not match, the tyre cannot be fitted.
Mounting Hole Parameters: The number of bolt holes, hole spacing and centre bore size must precisely match the original vehicle's axle head; any deviation in hole positioning will result in vibration whilst driving and bolt breakage.
Offset/Mounting Face: This determines the distance between the inner and outer edges of the rim; incorrect parameters will cause the rim to rub against the chassis or braking system, rendering it unusable.

Steel plate thickness: The thickness of the rim flange and spokes. In heavy-duty rims, using thinner material is strictly prohibited; greater thickness provides superior resistance to compressive deformation.
Rated load capacity: The standard load parameter per wheel. Select the appropriate model based on the combined weight of the equipment and its load; overloading is strictly prohibited to prevent rim fracture.
Stiffener Structure: Number and arrangement of stiffeners; denser and thicker stiffeners provide superior resistance to twisting and impact, making them suitable for rough mine terrain.

Concentricity Tolerance: Industry-leading high-precision standards; the smaller the tolerance, the smoother the equipment operation, reducing tyre wear and the risk of bolt fatigue failure.
Weld Parameters: Fully automated deep-penetration welding ensures uniform weld width and thickness, free from porosity and slag inclusions, thereby eliminating the common issue of weld cracking.
Surface Coating Thickness: The thickness of the anti-rust powder coating; the more uniform and substantial the coating, the better the resistance to corrosion and abrasion from gravel and stones.

Non-destructive testing grade: Non-destructive testing to detect internal hidden cracks and sand holes; heavy-duty wheel rims must undergo either 100% inspection or high-proportion sampling.
Fatigue test cycles: Simulates long-term heavy-load vibration to test the rim's fatigue limit; the higher the number of cycles, the greater the durability.
Certification upon dispatch: Certificate of Conformity, Material Test Report, and Pressure Test Report, meeting the acceptance requirements for mining and engineering tenders.
