Challenge Problems
Push your limits with challenges.
Question 1
If an excavator’s fill factor is 0.85 and actually digs at 60% of the optimum height with a swing angle of 100 degrees, calculate the productivity per hour.
💡 Hint: Pay attention to corrections from height and angle!
Question 2
Consider a site where the truck positioning leads to excessive waiting time. Discuss strategies to optimize truck exchange and the influence on excavation productivity.
💡 Hint: Think about how to implement efficient scheduling.
