Challenge Problems

Push your limits with challenges.

Question 1

A construction site has scrapers with a cycle time of 4.5 minutes. If the project shifts to a new area that increases haul time by 30 seconds, what is the new cycle time?

💡 Hint: Consider how each increment in time affects the overall cycle.

Question 2

If a loader scrapes 100 tons in an hour but increases the payload by 100% without modifying the loading efficiency, what will be the effect on the loading time and the production rate?

💡 Hint: Analyze the implications of load growth on the overall time.
