SIMPLIFIED RIGGING-RATING GUIDELINES
DETERMINING THE FORCES THROUGHOUT AN ARRAY REQUIRES
COMPLEX CALCULATIONS. THESE GUIDELINES ELIMINATE THE NEED
1. THESE SIMPLIFIED RIGGING-RATING GUIDELINES PROVIDE
RATINGS FOR TYPICAL ARRAYS BASED ON THE:
A. VERTICAL ANGLE OF EACH ENCLOSURE.
B. TOTAL WEIGHT OF EACH ENCLOSURE PLUS ALL
ENCLOSURES AND RIGGING SUSPENDED BELOW IT.
C. RELATIVE ANGLES OF THE FRONT RIGGING STRAPS.
D. RELATIVE ANGLE OF THE Xrhg OR Xrhp HINGES.
WORKING-LOAD RATINGS. OTHER ARRAY CONFIGURATIONS MAY BE
FOR WEIGHT-DISTRIBUTION CALCULATIONS BY UTILIZING CONSERVATIVE
