Challenge Problems
Push your limits with challenges.
Question 1
If a shovel has an average cycle time of 30 seconds and the truck is positioned at 120 degrees, how would you estimate the increase in cycle time? Calculate using an assumed factor for swing angles over 90 degrees.
💡 Hint: Review the swing angle impacts discussed earlier.
Question 2
A project requires you to optimize a shovel’s productivity running on a 6-hour shift. If the shovel operates efficiently for only 75% of that time, calculate the effective productive time. Include factors affecting operational time, like wait times for trucks and equipment adjustments.
💡 Hint: Account for the job efficiency discussed in class.
