Challenge Problems
Push your limits with challenges.
Question 1
A crane must lift a load weighing 18000 kg at a horizontal distance of 15 meters with a required lifting height of 30 meters. The load chart indicates that the crane can lif 20000 kg at this radius. Calculate if the crane can safely lift the load, considering the rigging weight of 1800 kg.
💡 Hint: Always sum up the rigging with the main load.
Question 2
The crane's boom length needed to lift a load 50 meters high at a 25-meter radius is determined using the crane range diagram. What boom length should you expect based on typical diagrams?
💡 Hint: Referring to diagrams can help visualize and plan for different configurations.
