What is the minimum tensile strength specification for the becket on general use pulleys?

The minimum tensile strength specification for the becket on general use pulleys is established at 19.5 k/N. This strength ensures that the pulley system can safely handle the loads typically encountered during rescue operations without risking failure. A becket that meets or exceeds this tensile strength is crucial because it serves as the attachment point for the rope and plays a key role in the overall integrity of the pulley system.

Using a pulley with an insufficient tensile strength rating could lead to catastrophic failures under load, potentially resulting in severe injury or fatality during rescue operations. The specificity of 19.5 k/N takes into account various factors including the materials used in manufacturing the pulleys, the dynamic loads experienced during rescues, and safety factors critical to ensuring resilience and reliability in high-stress situations. Understanding and adhering to these specifications is essential for anyone involved in technical rescue training and operations.
