The maximum list allowed for a land crane on a barge is?

Explanation:
In floating crane operations, stability depends on how much the barge lists (tilts to one side). A small list is tolerable, but there’s a defined limit to prevent unsafe conditions. Five degrees is the commonly accepted maximum list for a land crane on a barge because, as the barge tilts, the vertical line of the crane’s weight shifts relative to the hull, reducing the righting moment that resists further tilt. This makes the system more prone to tipping, and the crane’s capacity is also reduced as list increases. Staying within five degrees keeps the stability margin acceptable and ensures safe lifting conditions.
