SAFE LIFT APPROVED77% Rated

Net load (28,000 lbs) is within safe net capacity (37,100 lbs).

Union Operator's Exam Load Chart Cheat Sheet:

  • Always deduct rigging & hardware: Slings, shackles, spreader beams, and hook blocks count against chart capacity.
  • Interpolation rule: If operating radius falls between chart increments (e.g. 42 ft when chart lists 40 ft & 45 ft), ALWAYS use the capacity listed for the next LONGER radius (45 ft).
  • Bold line on chart: Values above the bold line are structural stability limits; values below are tipping stability limits.
  • Stowed extensions: A stowed jib creates a constant structural weight deduction regardless of whether it is used.
