| Wedge Dog Stops | Adjustable stops that fit various rail sizes. | Versatile use across different cranes. |
| Non-Slide Stops | Designed to prevent sliding of the crane. | Ideal for high-speed operations. |
Best Practices for Using Overhead Crane Stoppers
- Training Operators: Ensure all crane operators are trained on the proper use of stoppers and the importance of not relying solely on them to stop the crane.
-
Regular Inspections: Conduct routine inspections of stoppers to ensure they are functioning correctly and are not damaged.
-
Proper Installation: Follow manufacturer guidelines for installation to ensure stoppers are securely attached and can withstand operational forces.
-
Limit Switches: Consider using limit switches to cut power to the crane when it approaches the end stops, preventing potential collisions.
- Load Management: Always be aware of the load being lifted and ensure it does not exceed the stopper’s weight capacity.
Conclusion
Overhead crane stoppers are vital for ensuring safety and efficiency in lifting operations. By understanding the different types and technical features, operators can select the appropriate stoppers for their specific needs. Companies like Konecranes, Aldon Company, Overhead Lifting, and ULS Lifting provide a range of options to suit various applications. Implementing best practices will further enhance safety and operational efficiency.
