Crane Wheel Assemblies: High Load Capacity,
Wear & Fatigue Resistance

Suitable for overhead cranes, gantry cranes, and port cranes.
Supports both standard wheel dimensions and non-standard customization.
Compliant with FEM, ISO, DIN, and GB standards.

5 Crane Wheel Assemblies Types for Different Application Requirements

L Block Crane Wheel Assembly
- Wheels forged are typically made of 42CrMo or 65Mn.
- Integral welded structure.
- Equipped with labyrinth seals to prevent dust and moisture ingress.
45°Split Bearing Box Crane Wheel Assembly
- The wheel body is typically made of ZG340–640 or 42CrMo.
- 45° split bearing box design.
- Even load distribution with strong impact resistance.

Gear Ring Type Round Bearing Box Crane Wheel Assembly

Integrated Forging Crane Wheel Line Ensuring Quality & Short Lead Time

The production process integrates heating → forging → rolling → heat treatment → continuous precision machining, delivering high efficiency, fast production cycles, and short lead times.

Forged with ultra-high-tonnage presses.
All wheels undergo stress-relief treatment and surface hardening.
A dense microstructure and refined grains can extend service life by 20–50%.
Heat treatment significantly improves strength, toughness, and fatigue life.
