Challenge Problems
Push your limits with advanced challenges
Calculate the total time for a scraper with a cycle time of 7.78 minutes operating with a pusher of 1.37 minutes, taking into account loading, dumping, and travel times. How many scrapers should be operational for optimal efficiency?
💡 Hint: Break down the components of time and consider the operational limits.
If a hauling path increases gradient resistance to 30 kg per ton instead of 20 kg per ton, how would this affect the overall productivity of the scrapers? Calculate the impact on the estimated productivity.
💡 Hint: Consider how resistance prevents movement and slows down the loading process.
