How many cable clamps are required on a cable?

The requirement for a minimum of three cable clamps on a cable is based on safety and secure attachment principles in hoisting and rigging practices. The specific configuration of having a U-bolt on the dead end and a saddle on the live end ensures that the cable is affixed in a way that minimizes the risk of slippage or failure under load.

A U-bolt is often used on the dead end of the cable because it grips the cable securely, preventing it from sliding out of the clamp. On the live end, using a saddle helps distribute the load and maintain the integrity of the cable, which is crucial in applications that involve lifting or hoisting heavy loads. By employing this configuration, the cable maintains a strong connection, thus enhancing the overall safety of the rigging system.

Other configurations, such as having only one clamp on the dead end or only two clamps, do not provide sufficient redundancy or security. Involving three specific clamps with designated functions promotes not only safety but also compliance with established rigging standards. Thus, having a minimum of three clamps is essential for ensuring effective and safe operation in hoisting scenarios.
