Product Description

42CrMo Open die forging 500-1100mm Diameter Crane Wheels. Our 42CrMo alloy steel crane wheels, forged using the open die process, are designed for heavy-duty applications in port handling, lifting systems, and industrial cranes. With diameters ranging from 500mm to 1100mm, these wheels offer outstanding load-bearing capacity, wear resistance, and impact strength, making them ideal for continuous operation in demanding environments.


Forged from high-quality 42CrMo, the wheels undergo quenching and tempering to achieve optimal mechanical performance and dimensional stability.

Key Features:

  • Material: 42CrMo alloy steel

  • Diameter Range: 500mm – 1100mm

  • Forging Method: Open die forging + rough machining

  • Heat Treatment: Quenched and tempered for high strength and toughness

Applications:

  • Port gantry cranes (STS, RTG, RMG)

  • Overhead cranes and hoisting systems

  • Rail-based transport and transfer systems

  • OEM replacements for brands such as ZPMC, Konecranes, etc.

Advantages:

  • Uniform grain structure and high load resistance

  • Long service life with low maintenance

  • Custom bore size, keyway, and hub configurations available

  • Ultrasonic tested, dimensionally verified, and fully traceable

Our laboratory testing equipment includes:

Spectral Component Analyzer – for chemical composition analysis

Hydraulic Universal Testing Machine – for tensile and yield strength testing

Impact Strength Testing Machine with Cryogenic Tank – for room temperature and low-temperature impact testing

Brinell & Rockwell Hardness Testers – to assess surface and core hardness

Ultrasonic Flaw Detector – for internal defect detection (UT)

Metallurgical Microscope – for grain structure and heat treatment evaluation

Program-Controlled Box Furnace – for heat treatment simulations and metallurgical testing
