🪢 ASME A17.1 (Safety Factor SF >12, Sheave-to-Rope Ratio D/d ≥ 40, Fatigue Cycles)

Traction Elevator Wire Rope Safety Calculator

Size hoist and compensation steel wire ropes for high-speed traction passenger elevators under ASME A17.1/CSA B44 Section 2.20: calculate required static factor of safety (SF > 12 based on car speed up to 1,400 FPM), drive sheave D/d bending ratio (≥ 40:1 to prevent reverse-bend fatigue wire breaks), and elevator maintenance profits.
