- Manufactured fully complying with OEM drawing specifications, mounting hole spacing and outer contour consistent with original spare parts. Plug-and-play installation without modification, greatly reducing equipment maintenance downtime.
- Constructed from high-strength low-alloy thick steel plate, with stress relief heat treatment to eliminate welding residual stress. Excellent impact resistance, resisting permanent deformation and cracking under heavy load and bumpy working environments.
- Adopt multi-piece split structure design, lock ring and flange with high-precision matching, provide stable clamping force for tire bead, prevent tire slip and ring displacement under frequent loading impact, and simplify on-site tire maintenance and replacement.
- Heavy-duty anti-corrosion coating applied on the surface, capable of resisting mud, water and gravel abrasion, slow rusting rate, suitable for all-weather outdoor long-time operation.
- High precision bolt hole layout ensures uniform stress distribution after installation, reduces local stress concentration of wheel hub, protects axle and hub assembly and extends service life of walking system.

FAQ 

Q1: What symptoms mean the wheel rim needs to be replaced?
A1: Visible cracks, permanent deformation, severe corrosion and pitting on rim body; loose lock ring, frequent tire slipping; enlarged and out-of-round bolt holes, obvious shaking during driving.

Q2: Can the rim body be reused during tire replacement?
A2: The rim body can continue to be used if there is no crack, deformation or heavy corrosion. It is recommended to replace new lock ring and sealing accessories every time of tire replacement.

Q3: What key points should be noted during rim installation?
A3: Check rim, lock ring and flange for damage before assembly; confirm tire specification is 23.5-25; ensure lock ring is fully seated; tighten wheel bolts crosswise to specified torque value.

Q4: What hazards will be caused if the lock ring is not installed in place?
A4: The lock ring may pop out during operation, resulting in sudden tire deflation, which brings serious safety risks to loaders and operators.

Q5: Can this rim adapt to mine and aggregate yard working conditions?
A5: Yes, it is designed for heavy-duty working conditions such as mines, quarries and aggregate yards, with outstanding impact resistance and wear resistance.

Q6: What are the main causes of rim cracking?
A6: Long-term overload operation, violent impact from stones, uneven bolt tightening, residual welding stress without heat treatment, material fatigue and aging after long service.
