CRANE WHEEL Assembly
Crane wheel assembly work under continuous stress — carrying heavy loads, absorbing impact, and running on fixed rails over long periods.
OLICRANEPARTS supplies wheel assemblies for applications like port cranes, steel mills, and workshop lifting systems, where reliability is not optional.
We configure each set based on practical factors such as wheel load, rail profile, and service conditions, with both standard options and custom designs available.

Custom Crane Wheel Assembly Solutions
Not every crane system fits a standard wheel assembly. In many projects, factors like load distribution, rail profile, installation space, and working conditions require a more tailored approach.
OLICRANEPARTS provides custom crane wheel assemblies based on actual operating requirements. From wheel diameter and flange design to bearing housing structure and connection type, each component can be configured to match your system.
Whether you are replacing existing wheel sets or designing a new crane system, we support both standard modifications and fully custom-built solutions.
Core Selection Guide for Crane Wheel Assembly
| Selection Dimension | Core Selection Requirements | Key Notes |
|---|---|---|
| Basic Working Conditions | Clarify crane type, running speed, working environment and duty class; distinguish between low-speed heavy-duty/high-speed light-duty, indoor/outdoor scenarios. | Directly affects material, hardness and sealing requirements. |
| Load Parameters | Calculate total lifting load + crane dead weight, determine the number of wheels, arrangement method and maximum wheel load (kN/ton). | Determines wheel diameter, tread width and bearing model. |
| Wheel Structure & Dimensions | Structure: Flat tread (for straight running), conical tread (anti-rail gnawing), double-flanged (most commonly used); Dimensions: Diameter matches wheel load, tread width matches rail head. | The larger the diameter, the smaller the contact stress and the longer the service life. |
| Rail Matching | Match rail model (P24/P43/QU70, etc.), and the tread shape is completely consistent with the rail head. | Avoid uneven wear, rail gnawing and running vibration. |
| Material & Heat Treatment | Light-duty: ZG50SiMn; General heavy-duty: 65Mn; Heavy-duty: 42CrMo/forged steel; Hardness HB300-380, quenching depth ≥15-20mm. | The higher the duty class, the stricter the material requirements. |
| Bearing & Shaft | Commonly used: integral hub + double row spherical roller bearing; Axle is solid forged shaft, safety factor ≥2.5. | Split hub is easy to replace without removing the shaft. |
| Sealing & Lubrication | Outdoor/dusty environment: multi-channel labyrinth seal; High temperature: heat-resistant bearing + grease; Centralized lubrication system is optional. | Extends the service life of bearings and wheels. |
| Quick Selection Steps | 1. Confirm maximum wheel load → 2. Clarify working conditions/duty class → 3. Match rail and wheel dimensions → 4. Select material → 5. Determine bearing/axle set → 6. Check sealing and lubrication. | The rationality of selection can be verified with the manufacturer's load table. |
Why Choose Our Crane Wheel Assemblies
Our crane wheel assemblies are designed based on real operating conditions, with a focus on durability, load performance, and long-term reliability.
🔹 Forged Steel Construction
Wheels are manufactured from forged materials such as 42CrMo or 65Mn, ensuring better internal structure and higher resistance to impact compared to cast alternatives.
🔹 Controlled Heat Treatment
Heat treatment processes are applied to achieve the required hardness and depth, improving wear resistance while maintaining core toughness.
🔹 Precision Machining
All critical dimensions — including tread, flange, and bore — are machined to ensure proper alignment with crane rails and stable operation.
🔹 Adapted to Heavy-Duty Conditions
Designed to perform under continuous load, frequent starts and stops, and demanding environments such as ports and steel plants.
🔹 Flexible Design Options
Configurations can be adjusted based on project requirements, including wheel diameter, bearing housing type, and connection structure.
