What is the maximum allowed stirrup overhang for platforms?

• A. 10 inches
• B. 14 inches
• C. 18 inches
• D. 22 inches

Answer: (C)

Stirrup overhang is the distance the stirrup can extend beyond the edge of the platform. Limiting this distance helps control tipping moments and keeps the platform’s center of gravity within the supporting structure when it’s loaded with people and gear. The maximum allowed is 18 inches, a value chosen to balance practical working space with safety. Exceeding that limit increases the lever arm on the rigging and raises the risk of tipping or overstressing the suspension. Smaller overhangs are more conservative but reduce usable area, while a 22-inch overhang would be unsafe.
