When the hook is lowered to its lowest position, how many wraps of wire rope should remain on each side of the drum?

2026-03-04

When the hook is lowered to its lowest position, at least 3 wraps of wire rope should remain on each side of the drum. This is to ensure safety and prevent the wire rope from slipping off the drum. The specific reasons are as follows:

Safety: Retaining a sufficient number of wraps prevents the wire rope from slipping on the drum, avoiding accidents.

Prevent Equipment Damage: If the wire rope is fully released, it may cause excessive stress at the rope-to-drum connection point, potentially damaging the wire rope or the drum.

Maintain Normal Operation: Keeping a certain number of wraps ensures that the hook can maintain normal operating status even at its lowest position, preventing the lifting equipment from being affected by a rope that is too short.
