42CrMo4 Heavy Duty Steel Forging Blank for Port Crane Wheels

The 42CrMo4 heavy duty steel forging blank is specially engineered for port crane wheels, where extreme load-bearing capacity, repeated impact resistance, and dimensional durability are critical.

Forged from 42CrMo4 alloy steel—a chromium-molybdenum high-strength material —this blank undergoes open die forging and heat treatment to achieve excellent toughness, wear resistance, and fatigue strength, making it ideal for heavy-duty trolley wheels, traveling wheels, and lifting mechanisms operating in port terminals and shipyards.

The steel forgings production flow:

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

Application Scope

• Port Gantry Cranes: Traveling wheels, drive wheels, sheave wheels

• Container Cranes & RTGs: Heavy-load wheel blanks for horizontal movement systems

• Shipyard Gantry Lifts: Forging blanks used for trolley lifting components

• Steel Mill or Logistics Terminals: Industrial wheels subjected to abrasive surfaces and thermal gradients

Competitive Advantages:

Flexible, custom forging solutions tailored to client specifications

Raw materials sourced from reputable, certified steel mills

Short lead times and reliable delivery

Full traceability and stringent quality control at every step

Ideal for secondary machining and component manufacturing
