Tag Line Pull and Handler Count
Tag-line tension to control a suspended load, the number of handlers at a safe per-person pull, and a flag when a mechanical tag is needed. The lift director governs.
Formula and source
tag_tension = lateral_force / cos(angle); handlers = ceil(tag_tension / per_person); mechanical_help when tag_tension > 2 x per_person.
OSHA 1926 Subpart CC and standard rigging practice by name; first-principles statics on the tag-line geometry.
