Challenge Problems
Push your limits with advanced challenges
A crane has a weight of 10,000 kg, with counterweights of 5,000 kg and lifts a load of 8,000 kg at an operating radius of 12 m. Calculate the stability of the crane based on the overturning and stabilizing moments.
💡 Hint: Use the formula: Load Moment (overturning) vs. Weight Moment (stabilizing).
If a lattice boom crane can load 1,200 kg but weighs 600 kg, what will be the operational limits for using this crane at greater distances from its base?
💡 Hint: As the radius increases, consider how weight distribution affects tipping.
