Customized Free Forged Crane Wheel Hub For Heavy Duty Port

The Heat-Treated Crane Wheel Hub Free Forging is a precision-engineered forged component designed for extreme loads and repetitive motion environments in port and industrial crane systems. Manufactured from high-strength alloy or carbon steels such as 42CrMo4 or 45#, the hub delivers superior load-bearing performance, excellent fatigue resistance, and enhanced surface hardness after heat treatment. It supports flanged and solid wheel configurations, optimized for applications such as gantry cranes, RTGs, and heavy stackers operating in demanding coastal and heavy-duty environments.

Key Features:

• High structural integrity from open-die free forging with directional grain flow

• Quenching & tempering or normalizing treatment for wear and impact resistance

• Dimensional accuracy to ensure proper fit with axles, bearings, and locking mechanisms

• Suitable for integration with crane wheels or as a replacement component in wheel assemblies

Applications:

• Port gantry and container cranes

• Industrial bridge cranes and transfer carts

• Rail-mounted stacker and reclaimer systems

The steel forgings production flow:

Raw material steel ingot into warehouse(test the chemical composition) → Cutting→ Heating(Furnace temperature test) → Heat treatment after forging(Furnace temperature test) Discharge the furnace(blank inspection)→ Machining→ Inspection(UT,MT,Visal dimension, hardness)→ QT→ Inspection(UT, mechanical properties, hardness, grain size)→ Finish machining→ Inspection (dimension)→ Packing and Marking(steel stamp, mark)→ Storage Shipment.
