Challenge Problems
Push your limits with advanced challenges
You have an excavator with an optimum height of cut of 6 meters, and today you are working at 4.5 meters. If your correction factor for height is 0.83, what is your adjusted productivity if the ideal production is 400 m³/hr?
💡 Hint: Apply the correction factor to the ideal production.
A loader takes 25 seconds per cycle at optimum height with a 95-degree swing. If the ideal productivity is 600 m³/hr, how would you adjust for the angle of swing correction factor of 0.85?
💡 Hint: Don’t forget to multiply the ideal production by the correction factor.
