Heavy-Duty Gantry Crane Wheel Free Forging for Port and Industrial Crane Applications.The Heavy-Duty Gantry Crane Wheel Free Forging is a precision-engineered forged component designed to support the high loads and continuous rolling conditions in port cranes, shipyard gantries, and heavy industrial lifting systems. It serves as a critical wheel unit that ensures smooth, reliable movement of crane bridges and trolleys under extreme working environments.

Manufactured from high-strength alloy steels such as 42CrMo4, these wheels feature exceptional wear resistance, impact toughness, and load-bearing capacity. The free forging process ensures refined internal grain flow and structural integrity, minimizing internal defects and improving fatigue performance.

Key Features:

  • One-piece free forging for enhanced durability and structural consistency

  • Optional heat treatments (Q+T or normalizing) for surface hardness and core ductility

  • Machined treads, flanges, and bores with strict dimensional tolerances

  • Custom profiles for double-flanged, single-flanged, and flat-wheel designs

Applications:

  • Port gantry cranes, container terminals, shipyard bridge cranes

  • Rail-mounted stacking cranes, rubber-tyred gantry systems (RTGs)

  • Heavy industrial overhead cranes and transfer carts

Item Details
Product Name Heavy-Duty Gantry Crane Wheel Free Forging for Port and Industrial Crane Applications
Material Grades - High-strength steels: 42CrMo4 - Excellent wear resistance, surface hardness, and load-bearing performance in repetitive rolling operations
Forging Equipment - Hydraulic hammers: 5T / 8T / 12T - 3600T open-die forging press capable of producing large-diameter, solid or hubbed wheel forgings - Supports integrated tread and flange profiles
Manufacturing Process Hot Forging → Normalizing / Quenching + Tempering → Ultrasonic Testing → Rough / Semi-Finish Machining → Dimensional & Surface Inspection
Forging Ratio ≥ 3.0 — Promotes directional grain orientation for improved fatigue resistance and impact absorption in high-cycle crane operation
Applications - Gantry cranes and container stackers at ports and shipyards - Bridge cranes, RTGs, and industrial transfer carts - Rail-mounted and rubber-tyred crane systems
Heat Treatment Options - Quenched + Tempered for core strength and surface hardness - Normalizing for uniform grain refinement - Optional stress relief before finish machining
Testing & Inspection - Chemical: Alloy verification via spectrometer analysis - Mechanical: Hardness, tensile strength, yield, impact resistance (transverse & axial) - Ultrasonic (UT): Full-body flaw scanning - Dimensional: Tread concentricity, flange thickness, bore alignment
Value-Added Services - Pre-machining of flanges, bores, keyways, or custom tread profiles - Full traceability with heat number, forging batch, and inspection reports

The steel forgings production flow:

Raw material steel ingot into warehouse(test the chemical composition) → Cutting→ Heating(Furnace temperature test) → Heat treatment after forging(Furnace temperature test) Discharge the furnace(blank inspection)→ Machining→ Inspection(UT,MT,Visal dimension, hardness)→ QT→ Inspection(UT, mechanical properties, hardness, grain size)→ Finish machining→ Inspection (dimension)→ Packing and Marking(steel stamp, mark)→ Storage Shipment.
