What is the minimum breaking strength of a simple anchor?

The minimum breaking strength of a simple anchor being 20 kN is based on the established safety standards and parameters used within rope rescue and climbing practices. A breaking strength of 20 kN ensures that the anchor can withstand significant loads without failing. This value provides a crucial safety margin in rescue scenarios, where unexpected forces might occur due to dynamic movements, additional equipment, or the weight of a rescued individual.

Furthermore, using an anchor with a minimum breaking strength of 20 kN aligns with industry best practices, where both the strength of the anchor and the weight of the load it will bear are considered. This standard also takes into account the potential for wear and fatigue that may affect the anchor over time. Safety protocols emphasize the importance of using anchors that are rated adequately to handle not just the known weight but also any additional dynamic forces that can arise during a rescue operation.

In contrast, breaking strengths lower than 20 kN may not offer the same level of safety, especially in scenarios involving multiple rescuers, equipment, or when potential shock loading occurs. Therefore, a minimum of 20 kN ensures that the anchor is robust enough to support the demands of rope rescue operations effectively.
