Core Product Features & Advantages
High-Strength Forging Process
Manufactured from alloy steel via integral die forging. The process removes internal defects and improves overall structural strength. The rims withstand heavy crane loads and frequent high-intensity operation without deformation or cracking.
01
Wear & Corrosion Resistance
Treated with heat treatment and surface finishing for high hardness. The rims adapt to gravel, muddy and rough site conditions. The anti-rust coating prevents oxidation and corrosion to extend service life.
02
Precision Machining & Stable Fitting
CNC machining guarantees accurate dimensions, standard bolt holes and smooth tire grooves. It ensures tight fit with matched OTR tires, preventing tire shake, slippage and air leakage, and improving operational safety.
03
Smooth & Reliable Operation
Optimized structure balances stress distribution, reduces friction and vibration. It keeps cranes running smoothly and lowers equipment failure and maintenance costs.
