Rough Machined Crane Wheel in 4140 Alloy Steel Material

The Rough Machined Crane Wheel in 4140 Alloy Steel Material is engineered for demanding industrial environments where high strength, wear resistance, and dimensional reliability are critical. Forged from premium 4140 alloy steel and rough machined to your specifications, this crane wheel is ideal for heavy-duty lifting systems that operate under high loads and continuous cycles.

These are the main inspection equipments: 

Key Features

• Material: High-strength 4140 alloy steel with excellent hardenability and toughness

• Process: Precision open-die forging followed by rough machining

• Surface: Machined to near-net shape, ready for final machining or heat treatment

• Performance: Superior fatigue resistance and long service life under heavy loads

• Customization: Sizes, tolerances, and bore dimensions available upon request

Applications

This forged crane wheel is widely used in:

• Overhead cranes and gantry cranes

• Port container handling systems

• Mining and bulk material conveyors

• Steel mill transfer carts and hoisting equipment

• Industrial automation tracks and rail-guided vehicles

The steel forgings production flow:

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