What method is used to relieve tension on the rear jib support cables when stowing the A-frame jib?

The method used to relieve tension on the rear jib support cables when stowing the A-frame jib involves reeling in a hoist cable attached to the jib mast. This action effectively reduces the load on those cables by retracting or lowering the jib, which in turn relieves the tension. When the hoist cable is reeled in, it allows for controlled movement of the jib and the associated structural components, ensuring that the repositioning is done safely and efficiently.

This approach is crucial as it minimizes the risk of damage to the cables and the overall structure. On the other hand, attempting to manually adjust the cables could lead to improper tensioning or slack not addressing the underlying load concerns. Likewise, extending the jib mast or loosening the cable joints may not provide the necessary adjustments to alleviate tension effectively. Each of these methods lacks the direct control and precision provided by the hoist cable retraction, making it integral for safe operations in stowing the jib.
