The Heavy-Duty Crane Wheel Forged by Open Die Process is designed to perform in extreme working conditions where high
loads, impact, and continuous operation are present. Manufactured
through open die forging, this wheel features superior internal
integrity, refined grain structure, and exceptional mechanical
strength — making it ideal for heavy industrial lifting systems.
| 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. |
