Challenge Problems
Push your limits with challenges.
Question 1
A crane's tipping load is 120 tons. If it's operating with a safety margin of 75%, what is the man safe working load?
💡 Hint: Use the tipping load as a starting point to find the working load.
Question 2
If two different cranes, a crawler and a truck-mounted crane, are rated at 80 tons and 60 tons respectively, how much load can they lift combined when using outriggers?
💡 Hint: Think about how outriggers directly enhance the capacity allowed for lifting.
