Heavy Duty Free Forging Gantry Crane Wheel For Port And Industrial Crane
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
