Challenge Problems
Push your limits with challenges.
Question 1
A lattice boom crane has a load of 5000 kg at an operating radius of 10m. Calculate the overturning moment if the distance to the tipping axis is 5m.
💡 Hint: Consider how the load's weight contributes to the tipping moment.
Question 2
If a truck-mounted crane's manufacturer rated its maximum load at 100 tons, but the crane is set up on a sloped surface and outriggers are not used. How should you adjust the lifting capacity?
💡 Hint: Reflect on how surface conditions affect crane operations.
