Challenge Problems

Push your limits with challenges.

Question 1

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.

Question 2

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.
