Ultrasonic Tested Heavy Forged Steel Parts For Gantry Container Crane Wheels

This 42CrMo Ultrasonic-tested Heavy Steel Forging For Gantry Container Crane Wheels is specifically engineered for use in overhead crane wheels, gantry crane trolleys, and rail-driven lifting systems, where high impact resistance, load-bearing capacity, and dimensional integrity are crucial.

Forged from high-strength 42CrMo alloy steel, the component undergoes open die forging, Q+T heat treatment, and ultrasonic testing (UT) to ensure a dense internal structure and eliminate subsurface defects. Its excellent toughness and wear resistance make it ideal for wheel rims, hubs, and rail-contacting surfaces subjected to cyclic stress and abrasive environments.

Specifications

• Weight Range: 100 kg – 7 tons (customized to accommodate both medium-size drive shafts and large-section marine components)

• Machining-Ready Surface: Delivered with precise allowances for final CNC finishing

• Grain Structure: Refined through forging ratio ≥3.0 and controlled heat treatment

• Tensile Strength & Toughness: Tuned to meet ship classification society requirements

• Dimensional Tolerance: Custom tolerances per project needs

Application

This product is optimized for:

• Crane traveling wheels and drive wheels in metallurgical plants

• Trolley wheels in container gantry cranes at ports and terminals

• Rail wheel components for heavy lifting assemblies in mining or hydropower sectors

• Forged hubs for steel mill cranes operating under high temperature and shock environments

Advantages:

High Strength & Toughness

• 42CrMo alloy steel offers an ideal balance of high tensile strength, ductility, and impact resistance, enabling safe operation under sudden loading and high-frequency braking in crane systems.

Ultrasonic Tested for Internal Integrity

• Each forging undergoes ultrasonic inspection, ensuring defect-free structure with no internal cracks, shrinkage cavities, or inclusions—critical for rotating components like crane wheels.

Enhanced Wear Resistance

• Through quenching and tempering (Q+T) treatment, the forging achieves , significantly reducing wear at the wheel-rail interface and extending service life in abrasive environments.

Optimized Grain Flow

• The controlled forging ratio (≥3.0) ensures grain alignment along stress paths, improving fatigue resistance and reducing the risk of fracture or deformation under heavy cyclic loads.

Precision Machinability

• Material composition and thermal refinement allow high-precision CNC machining, enabling tight tolerance control for wheel hubs, bores, and flanges to match complex crane drive designs.

Reliable Performance in Harsh Conditions

• Suitable for extreme operating environments, such as steel mills, port gantry cranes, and mining hoists, where equipment faces high thermal cycles, shocks, and corrosive exposure.

Customization-Friendly

• Available in various sizes, machining states (rough/finish), and bore/keyway configurations, the forging can be tailored to specific crane models or OEM requirements.
