Tag Line Pull and Handler Count
Tag-line tension to control a suspended load, the number of handlers at a safe per-person pull.
Example
You enter
- Lateral force to resist (lb) 328
- Tag-line angle above horizontal (deg) 30
- Safe pull per handler (lb) 50
You get
- Tag-line tension 378.7 lb
- Handlers at the per-person limit 8
Checked against published worked examples from: OSHA 1926 Subpart CC / rigging practice.
Details, formula, and sources
ScopeTag-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 or tabletag_tension = lateral_force / cos(angle); handlers = ceil(tag_tension / per_person); mechanical_help when tag_tension > 2 x per_person.
Source and editionOSHA 1926 Subpart CC and standard rigging practice by name; first-principles statics on the tag-line geometry.
Free accessOSHA 1926 Subpart CC is free at osha.gov. The geometry is public.
What governsEstimate. Head rigger and manufacturer working-load-limit charts govern. Inspect every piece of hardware before the show.
