The Large 42CrMo Forged Crane and Port Machinery Wheels for Heavy-Duty Applications are engineered for superior strength, durability, and reliability in demanding industrial environments. Manufactured from high-quality 42CrMo alloy steel, these wheels are produced through precision open-die forging, followed by optimized heat treatment to achieve excellent hardness, toughness, and wear resistance. Each wheel undergoes rigorous non-destructive testing, including ultrasonic and magnetic particle inspection, ensuring flawless internal integrity and compliance with international quality standards.
| Item | Details (Heavy-Duty Open Die Forged Crane Wheel) |
|---|---|
| Material | 4140 Alloy Steel – Offers excellent shock resistance, fatigue durability, and wear performance under dynamic heavy-load conditions. |
| Forging Capability | Hydraulic Hammers: 5T / 8T / 12T – Enable deep plastic deformation and directional grain refinement during open die forging, ensuring internal soundness. |
| Main Application | Developed for large-scale lifting systems, including gantry cranes, port cranes, and heavy-duty container carriers operating in high-load environments. |
| Production Process | Open Die Forging → Heat Treatment (Normalizing + Tempering) → Rough Machining – Delivers high strength and dimensional accuracy throughout the process. |
| Deformation Ratio | Forging Ratio ≥ 3.0 – Improves grain flow alignment and reinforces load-carrying structure, reducing the risk of internal failure under fatigue. |
| Delivery State | Delivered as rough-machined and heat-treated, including stress relieving to prevent deformation during final machining or service. |
| Inspection Tools | Comprehensive testing with: Spectrometer, UT device, tensile & impact machines, metallographic scope, micrometers, bore indicators, hardness testers, etc., ensuring traceable quality control. |
| Service Package | Tiangong Forging offers an end-to-end service, including forging, machining, heat treatment, quality inspection, custom packing, port clearance, and global shipment coordination — fully aligned with client specifications and international standards. |
These are the main inspection equipments:
| Our Lab inspection equipment | |
| 1 | Spectral component analyzer |
| 2 | Impact strength testing machine |
| 3 | Impact test cryogenic tank |
| 4 | Ultrasonic flaw detector |
| 5 | Brinell hardness tester |
| 6 | Rockwell hardness tester |
| 7 | Digital hydraulic universal testing machine |
| 8 | H.Metallurgical microscope |
| 9 | Program-controlled box furnace |
Key Features
Material Excellence – 42CrMo alloy steel offers high tensile strength, impact resistance, and superior fatigue performance.
Forging Precision – Dense internal grain structure for enhanced load-bearing capacity and extended service life.
Surface and Core Strength – Uniform hardness distribution to resist deformation under heavy loads.
Quality Assurance – 100% UT and MT inspections to guarantee defect-free performance.
Applications
These forged wheels are ideal for heavy-duty port cranes, gantry cranes, container handling systems, and other harbor machinery. They are also suitable for use in mining transport equipment, large metallurgical machinery, and rail-mounted lifting systems, providing stable and reliable operation under high-load, high-impact conditions.
