42CrMo Open die forging 500-1100mm Diameter Crane Wheels. Our 42CrMo alloy steel crane wheels, forged using the open die process, are designed for heavy-duty applications in port handling, lifting systems, and industrial cranes. With diameters ranging from 500mm to 1100mm, these wheels offer outstanding load-bearing capacity, wear resistance, and impact strength, making them ideal for continuous operation in demanding environments.

Forged from high-quality 42CrMo, the wheels undergo quenching and tempering to achieve optimal mechanical performance and dimensional stability.

Key Features:

• Material: 42CrMo alloy steel

• Diameter Range: 500mm – 1100mm
