42CrMo Forged Wheels for Gantry Cranes and Heavy Port Handling Equipment.Manufactured from premium 42CrMo alloy steel, these forged wheels are designed to withstand extreme mechanical stresses and ensure long service life in heavy-duty industrial environments. The forging process refines the steel’s internal structure, providing exceptional strength, toughness, and wear resistance. Precision machining guarantees tight dimensional tolerances, smooth rolling performance, and compatibility with various crane and port handling systems.
Key Features
High Strength & Toughness – 42CrMo alloy steel offers superior load-bearing capacity and impact resistance.
Excellent Wear Resistance – Heat-treated surface resists abrasion under high-load rolling conditions.
Dimensional Accuracy – Precision machining ensures perfect fit and smooth operation.
Long Service Life – Designed for extended performance in demanding working environments.
Applications
These forged wheels are widely used in:
Gantry Cranes – Heavy lifting operations in shipyards, construction sites, and logistics hubs.
Heavy Port Handling Equipment – Container cranes, rail-mounted gantries, and ship-to-shore systems.
Industrial Transport Systems – Rail carts, transfer trolleys, and other load-bearing wheel systems.

| Product Name | 42CrMo Forged Wheels for Gantry Cranes and Heavy Port Handling Equipment |
| Material Grades | - Alloy steel: 42CrMo — Delivers high tensile strength, excellent toughness, and outstanding wear resistance for long service under heavy rolling loads. |
| Forging Equipment | - Hydraulic hammers: 5T / 8T / 12T — Capable of forging thick-section wheel blanks. - 3600T open-die forging press — Ensures uniform internal structure and dense grain flow. - Specialized wheel blank tooling for precise hub and rim profile formation. |
| Manufacturing Process | Steel billet cutting → Hot forging (wheel blank formation) → Heat Treatment (quenching + tempering) → Ultrasonic testing → CNC machining of tread, hub bore, and mounting surfaces → Final dimensional inspection. |
| Forging Ratio | ≥ 3.0 — Promotes uniform fiber flow from hub to rim, improving fatigue resistance and load capacity in cyclic rolling operations. |
| Applications | - Gantry crane travel wheels in shipyards, construction, and container terminals. - Rail-mounted port handling equipment for container loading/unloading. - Heavy-duty industrial transfer carts and crane bogies. |
| Heat Treatment Options | - Quenched + Tempered — High strength and toughness for continuous heavy load operation. - Induction hardening of tread surface for extended wear life. - Optional stress relief to minimize distortion before precision machining. |
| Testing & Inspection | - Chemical: Spectrometer analysis of composition. - Mechanical: Tensile, yield, hardness, and Charpy impact tests. - NDT: 100% Ultrasonic Testing (UT) for internal defect detection. - Dimensional: Tread diameter, bore size, runout, and concentricity verification. |
| Value-Added Services | - Precision machining of hub bore, keyways, and bolt holes. - Surface finishing (shot blasting, anti-corrosion coating). - Export-grade packaging for overseas transport. - Full traceability with heat number, batch number, and certified mechanical & NDT reports. |
