When ought one to employ a tagline?

From the top of the reel to the top of the drum, the rope extends.

The separation between the load’s center of gravity and the crane’s center of rotation

When a load’s rotation could be hazardous 1910.180(h) & 1926.1417(w)(3)(xvi) If it becomes essential, a tag or restraint line must be employed to stop the weight from rotating in a dangerous way.

Crane capacity in the gray regions above the bold lines are determined by hydraulic or structural constraints. Based on stability ratings, the crane capacity are below the bold lines.
