6 sample questions

Question 1.
What is the ideal angle of swing for maximum productivity?
Show hintHide hint
Think about the angle that reduces unnecessary swing.
Question 2.
Define cycle time in excavation terms.
Show hintHide hint
Consider it similar to a round trip in transportation.
3Question 3.
What happen to productivity if the angle of swing exceeds 90 degrees?
- It increases
- It decreases
- It remains the same
Show hintHide hint
Think about how extended swings increase movement.
4Question 4.
Is it true that a correction factor of 1 indicates no needed adjustment?
- True
- False
Show hintHide hint
Recall what a correction factor represents.
Question 5.
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?
Show hintHide hint
Apply the correction factor to the ideal production.
Question 6.
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?
Show hintHide hint
Don’t forget to multiply the ideal production by the correction factor.
