Challenge Problems
Push your limits with challenges.
Question 1
Calculate the cycle time if a scraper has the following times: LT = 0.8 min, HT = 3.5 min, DT = 1.2 min, RT = 2.3 min, ST = 0.5 min, TT = 0.25 min. Consider also ADBT = 0.15 min. What is the total cycle time?
💡 Hint: Add all the specified times together following the formula.
Question 2
A project has two haul routes, one taking 5 min to traverse and the other taking 3 min. The loader takes 2 min, dump time is 1 min, and return time is 4 min. What can be done to reduce the cycle time?
💡 Hint: Identify the longest process and see how you can enhance its efficiency.
