What is ISO 4309?

ISO 4309 is the international standard covering the inspection and maintenance of crane rope. ISO 4309 provides internationally respected criteria for the discard of wire rope as installed on cranes and other lifting appliances.

What are the benefits of ISO 4309 compliance?

1. Improved Safety

ISO 4309 allows you to perform inspections on crane rope with full confidence that you are operating safely. With discard criteria to cover all the main modes of deterioration, including deformation, corrosion, broken wires, and wear, you can be sure that everything has been covered when you use the standard.

2. Improved Rope Life

ISO 4309 allows you to quantify the factors that lead to wire rope deterioration. By quantifying these factors, you can buy a rope that is more resistant to whatever is causing you the most issues. In the long-term, these improved procurement decisions can help you significantly improve wire rope life.

3. Faster Inspections

With procedure comes practice, and with practice comes speed. Applying a consistent framework to your crane rope inspections allows your inspectors to get better at what they do, and therefore faster.

4. Greater Surety

ISO 4309 allows you to perform inspections with greater certainty and lets you be sure that you are doing the right thing. Think about how much stress you would save yourself if you didn't have to debate whether a rope was safe or not with your colleagues!

The standard covers almost all situations you may encounter with your crane rope and can be used to make most of your rope decisions for you.

5. Supports Magnetic Rope Testing

ISO 4309 provides discard criteria for MRT inspections. The standard provides guidance for both Loss of Metallic Area (LMA) and Local Fault (LF) traces.

MRT is particularly useful for identifying internal wire rope corrosion.

6. Improved Consistency of Inspections

By applying a standard to inspecting your ropes, you can achieve greater consistency between inspections. Improving uniformity allows you to leverage previous inspection reports and data to improve your crane rope operation.

7. Greater Credibility

More and more companies are insisting that their external inspectors use ISO 4309. If you are an inspection company, using ISO 4309 will boost your credibility, and therefore your ability to get and retain customers.

8. Reduced Chance of Damaging Your Ropes

ISO 4309 provides guidance on how to install your ropes correctly. Following the guidance will significantly reduce your chances of damaging your ropes during installation.

9. Reduced Insurance Costs

ISO 4309 compliance means fewer accidents, and fewer accidents mean cheaper insurance.

10. Reduced Exposure to Risk

ISO 4309 compliance helps you reduce your exposure to risk from both a workforce and business point-of-view. ISO 4309 reduces the risk for your workforce by improving safety and for your business by improving your safety posture. If an accident does strike, using ISO 4309 will prove that you have taken every possible step to ensure safety around your crane rope.

11. Condition Based Monitoring

ISO 4309 provides a framework to switch to condition based monitoring (CMB). CMB can help you:

• Minimise unplanned downtime.
• Predict the future condition of your rope.
• Integrate your data with computerised maintenance management systems like Rope IQ.

Conclusion

ISO 4309 provides many benefits to organisations looking to make the switch. If utilised to its full potential, ISO 4309 allows organisations to dramatically reduce risk, improve safety, and with the right tools, cut costs.
