Working Load Limit (WLL) vs. Minimum Breaking Strength (MBS)
Safety margins are built into every rigging component to account for dynamic loading, wear, and minor calculation variances.
: Model, boom length, operating radius, and net capacity at that specific radius.
When searching online for verified training manuals, calculation matrices, and industry guidelines, target these authoritative organizations:
