Challenge Problems
Push your limits with advanced challenges
An excavator has an optimum height of cut of 7 meters, while the actual height it is operating at is 4.5 meters. Calculate the percentage of the optimum height and determine the correction factor needed if the table suggests a correction factor of 0.85 for this height.
💡 Hint: Calculate the percentage first, then use the correction factor.
If the average angle of swing is measured at 130 degrees, how would you modify your productivity estimates based on the provided correction factors for differing angles?
💡 Hint: Review swing angles and their corresponding productivity impacts.
