Customized 42CrMo Forged Blank For Ship-to-Shore Crane Wheels Trolleys

Customized 42CrMo Forged Blank for Ship-to-Shore Crane Wheels,Trolleys.This customized 42CrMo forged blank is specially engineered for ship-to-shore (STS) crane wheels and trolley systems operating in high-load port environments.

Manufactured through precision open die forging and optimized heat treatment, the block provides outstanding tensile strength, fatigue resistance, and impact toughness. The refined grain structure ensures long service life and stability under dynamic, repetitive stresses, making it ideal for critical wheel hubs and rotating assemblies in heavy-duty port machinery.

Key Features:

• High-Strength Alloy: Made from 42CrMo alloy steel with excellent mechanical properties

• Refined Grain Structure: Achieved through controlled forging ratio ≥3.0 to improve fatigue performance

• Custom Dimensions: Available in tailored sizes, shapes, and machining allowances based on customer drawings

• Machinability: Excellent for subsequent CNC or conventional machining with high dimensional stability

• Testing & Certification: Includes UT, MT, chemical, mechanical, and dimensional inspection reports on request

Application Fields:

• STS Cranes: Forged wheel hubs, trolley wheels, and drive components

• Gantry Cranes: Structural wheels and rotating load-bearing elements

• Port Logistics Equipment: Container movers, rail transfer trolleys

• Heavy-Duty Handling Systems: Wheel blanks for lifting and transport systems in marine terminals

• Shipyard Cranes: Running wheels, hub supports, and precision-machined wheel blanks

The steel forgings production flow:

raw material inspection → unloading → inspection → preheating → forging → heat treatment → inspection → rough machining → non-destructive testing → inspection → packaging → delivery.
