ZPMC Port Rotary Forged Wheels Open Forging 42CrM Alloy Forged Wheel

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.

Forging process flow quality control:

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.
