What is the distance from the load line to the tipping axis referred to as?
💡 Hint: Focus on the definitions we've just discussed.

Challenge Problems
Push your limits with advanced challenges
A truck-mounted lattice boom crane has an operational radius of 50 feet with a maximum lifting capacity of 80 tons. If the operational radius increases to 70 feet, what will happen to its lifting capacity? Discuss mathematically and conceptually.
💡 Hint: Refer back to our discussion on operational radius and tipping stability.
Given that a crane is rated for a maximum load of 100 tons on a level surface, calculate how this must change when operating on an uneven surface without outriggers. Provide a brief explanation.
💡 Hint: Consider how ground stability affects lifting capacity.
