Challenge Problems
Push your limits with advanced challenges
A crane is lifting a load with a weight of 800 kg. If the operational radius is 12 meters, calculate the maximum allowed lift based on a 75% safety margin.
💡 Hint: Apply the safety margin to the load weight.
Analyze a scenario where a truck-mounted crane has a tipping load of 2000 kg. If the operational radius is increased from 5m to 15m, discuss the implications for stability and lifting capacity.
💡 Hint: Focus on how the load position influences stability.
