What must be fitted to flanged boom pins once they are installed?

Locking pins are essential for securing flanged boom pins after installation. Their primary function is to prevent the boom pins from becoming dislodged during operation, which is crucial for maintaining the stability and integrity of the rigging setup. By ensuring that these locking pins are fitted, they provide an additional layer of safety, reducing the risk of accidental release or movement of the boom.

The use of locking pins is standard practice in rigging to enhance safety measures. It is critical that these components are used as designed, as they help to ensure that the equipment operates as intended, thereby protecting both the equipment and personnel involved in the lifting operation.
