Compare the heights involved in excavation.
What is the ideal angle of swing for maximum productivity?
Think about the angle that allows most efficient operations.
True or False: A greater angle of swing leads to shorter cycle times.
Consider what happens to the swing path.
A shovel with a heaped volume of 5m³ operates with a fill factor of 0.9. If the cycle time is 25 seconds, calculate the productivity if the optimal height is 6m but the actual height is 4.5m.
Remember to adjust for the actual height.
