What must be ensured regarding the suspension ropes during boom assembly?

Ensuring that suspension ropes do not interfere with the boom pins during boom assembly is crucial for the safe operation of cranes. The boom pins are essential components that secure the boom in place, allowing it to function correctly and safely while lifting loads. If the suspension ropes are positioned in a way that obstructs or interacts with the boom pins, it can lead to potential hazards, such as improper assembly or even mechanical failure during operation. In addition, any interference could compromise the integrity of the lifting mechanism and pose a risk to personnel and equipment. Therefore, keeping the suspension ropes clear from the boom pins is a fundamental safety measure while assembling the boom.
