The first variable: knowing exactly what you are lifting. Manufacturer Reference Books At a angle, the tension

The fleet angle is the angle between the centerline of a wire rope lead and the sheave flange. Poor fleet angles cause severe rope wear and improper spooling on the drum. Fleet Angle Limits Maximum 1.5° Grooved Drum Winch: Maximum 2.0°

A rigging plan cannot look at the load in isolation; it must account for the machine performing the lift and the ground supporting it. Crane Capacity Deductions
