Types of Overhead Crane Wheels
Overhead crane wheels can be categorized into several types based on design, application, and material. Understanding the differences helps in selecting the most suitable type for specific operational needs.
| Type | Description | Applications |
|---|---|---|
| Double Flange Wheels | Features two flanges for added stability and alignment. | Used in bridge and gantry cranes. |
| Single Flange Wheels | Has one flange, making it easier to navigate curves and turns. | Suitable for lighter cranes and trolley systems. |
| Non-Flange Wheels | Lacks flanges, providing flexibility and reduced friction. | Commonly used in specialized applications. |
| Forged Wheels | Made from forged steel, offering higher durability and strength. | Heavy-duty industrial applications. |
| Cast Wheels | Produced by casting processes; generally less expensive. | Suitable for standard lifting operations. |
Key Differences Among Wheel Types
Each type of crane wheel comes with its own set of advantages and disadvantages based on the manufacturing process, material used, and intended application. Here’s a detailed comparison:
| Wheel Type | Advantages | Disadvantages |
|---|---|---|
| Double Flange | Enhanced stability, better alignment | Heavier and may increase overall crane weight |
| Single Flange | Lighter, easier maneuverability | Less stability, may require more maintenance |
| Non-Flange | Flexible, reduced friction | May not provide sufficient support for heavy loads |
| Forged | Higher tensile strength, longer lifespan | Typically more expensive than cast wheels |
| Cast | Cost-effective, suitable for standard use | Generally less durable than forged options |
