Products Description
Our 8.5-20 two-piece construction machinery rim is a split heavy-duty steel wheel specially developed for small wheel loaders, light mining haul trucks and municipal engineering vehicles. Made of high-strength low-alloy steel Q355B, this two-piece rim consists of rim barrel and lock ring, equipped with standard engineering yellow anti-corrosion coating. It adopts thickened barrel design and optimized bolt connection structure, with strong load-bearing capacity, excellent impact resistance and convenient tire disassembly performance. All dimensions are strictly calibrated, fully matching 8.5-20 engineering tires, widely applied in construction sites, quarries, open-pit mines and road maintenance projects.
Why Choose Our Two-Piece Construction Machinery Rim?
One-stop engineering wheel procurement
Dual material optional: Cost-effective Q235B and high-load Q355B for different working condition budgets.
Low maintenance cost: Split two-piece design cuts tire replacement labor time by 40% compared with integrated rim.
Full in-house processing: Forming, welding, heat treatment, painting one-stop workshop, control product quality in whole links.
Product Advantages
Modular Two-Piece Split Design, Easy Tire Maintenance
Separate lock ring structure allows fast tire mounting & replacement without disassembling the whole wheel hub, greatly saving workshop maintenance time and labor cost, ideal for equipment with frequent tire wear in mines and construction sites.
High-Strength Steel Raw Material, Excellent Anti-Impact Performance
Optional Q235B general carbon steel and Q355B low alloy high strength steel; customized special alloy material available for ultra-heavy load scenarios. Thickened rim wall structure, strong resistance to bump impact and cyclic fatigue deformation under rough road operation.
