Reliable Forged Crane Wheels – ZPMC’s Leading Supplier at Your Service. ZPMC Port Crane Wheel Supplier – 42CrM Alloy Forged Wheel. We supply high-strength 42CrMo alloy forged wheels specifically designed for ZPMC port cranes and other heavy-duty lifting equipment. Manufactured through precision open die forging and strict heat treatment, our crane wheels are engineered to deliver exceptional load-bearing capacity, wear resistance, and impact strength under harsh working conditions.
These forged wheels are widely used in gantry cranes, ship-to-shore (STS) cranes, rail-mounted container cranes (RMGC), and rubber-tyred gantry cranes (RTGC), offering long service life and reduced maintenance for continuous port operations.
Key Features:
Material: 42CrMo
Forging Method: Open die forging
Heat Treatment: Normalizing and tempering for optimal hardness and toughness
Applications:
ZPMC STS & RTG cranes
Rail-mounted and rubber-tyred gantry cranes
Container handling systems
Heavy-duty port transport systems
Advantages:
Excellent wear and fatigue resistance
Precise dimensional control and concentricity
Compatible with OEM crane standards (e.g. ZPMC)
Custom machining and surface treatment available
Long service life under continuous operation
We design and manufacture forged parts for all industrial areas by applying our experience and unique professionalism, taking into account the specific technical and performance requirements of each market. This has made us a trusted forging partner across a wide range of industries, collaborating with world-leading companies.
