Challenge Problems
Push your limits with challenges.
Question 1
If a truck-mounted crane has an operating radius of 15m with a load line measuring 12m from the center, calculate the changing safe working load as the radius increases to 18m under the same conditions.
💡 Hint: Use values of X in the equation to understand how L is affected by radius change.
Question 2
A crane capable of lifting 200 tons at maximum capacity fails to stabilize due to insufficient outrigger extension. If conditions are remedied and load is reduced to 80 tons, how will the operational guidelines change?
💡 Hint: Consider the factors like ground conditions and load distribution.
