What is the maximum load angle from a sheave or pulley before a redirection is required?

The maximum load angle from a sheave or pulley before a redirection is required is 10 degrees. This standard is established to ensure safe rigging practices when handling loads. When the angle exceeds this threshold, the forces acting on the rigging can lead to increased stress and potential failure of the equipment or slippage of the load. Maintaining the load angle at or below 10 degrees helps in optimizing the mechanical advantage of the pulley system, ensuring more control and reducing the risk of accidents.

Understanding this limit is crucial for technicians working in telecommunications and rigging contexts, as it directly impacts safety, equipment integrity, and operational efficiency.
