Steel Wheel Set
Description:
The steel wheels are essential components for various types of cranes, including overhead cranes and gantry cranes. The wheels are forged from high-quality materials such as 60#, 65Mn, and 42CrMo to ensure durability and performance.
The wheel block is designed with a specialized bearing surface, while the trolley frame, end carriage, and wheel assembly support surfaces undergo precision processing. This design guarantees minimal horizontal and vertical deflection of each wheel, enabling high-precision assembly, smooth operation, and easy replacement.
The wheel block’s bearing support adopts a corner box structure, which is securely fixed to the trolley frame or the crane end beam’s bending plate using bolts. This structure allows wheel adjustments during use and maintenance, ensuring proper horizontal and vertical alignment to prevent rail gnawing. The corner box structure is a widely adopted and proven technology in China, offering reliability and ease of maintenance.
Features:
-
The wheel diameter and material selection are designed to withstand the most demanding operating conditions, ensuring that no part of the wheel is subjected to overload under maximum load-bearing forces.
-
The wheels are manufactured from 65Mn or ZG430-640 (CL60) cast steel, with the tread and inner flange surfaces undergoing high-frequency induction heat treatment. The hardness and quenching requirements comply with the following technical standards:
-
Tread and inner flange hardness: HB 300–380
-
Minimum quenching depth: ≥ 20mm
-
Minimum hardness of the hardened zone: HB 260
-
Welding repairs on the tread or inner flange are strictly prohibited, as they may compromise the wheel's performance and structural integrity.
