Question 1

What happen to productivity if the angle of swing exceeds 90 degrees?

  • It increases
  • It decreases
  • It remains the same

💡 Hint: Think about how extended swings increase movement.

Question 2

Is it true that a correction factor of 1 indicates no needed adjustment?

  • True
  • False

💡 Hint: Recall what a correction factor represents.

Challenge Problems

Push your limits with challenges.

Question 1

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.

Question 2

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.
