By what method should boom sections be lifted?

Lifting boom sections using lifting lugs is the correct method because lifting lugs are specifically designed for handling heavy loads safely and efficiently. These lugs are attached to the boom sections and provide designated points for a secure connection, ensuring proper weight distribution during the lifting process. This minimizes the risk of structural damage to the boom and enhances safety for personnel involved in the lifting operation.

Using chains or hooks may not be recommended as they can lead to improper load distribution, especially if they are not attached to the lugs or designed to handle the specific shape and weight of the boom sections. Manual lifting is also not advisable due to the risk it poses to workers' safety and the potential for injury. Employing lifting lugs is essential for adhering to safety standards and ensuring that the boom sections are handled correctly during installation or maintenance.
