Challenge Problems
Push your limits with advanced challenges
A scraper has a heaped capacity of 30 m³. If the swell factor is modified by a 15% increase when a pusher assists, calculate the effective bank volume it can carry.
💡 Hint: Split the problem into steps, starting with the effective load and then modifying the swell factor.
Calculate the total cycle time if a scraper has loading time of 1.2 minutes, dump time of 0.5 minutes, and return to load time of 2 minutes.
💡 Hint: Make sure to factor in all components, even shorter ones.
