Challenge Problems

Push your limits with challenges.

Question 1

A shovel has a heaped bucket volume of 4 cubic meters, a fill factor of 0.8, and operates at an actual height of cut of 3 meters with an optimum height of 4 meters. Calculate its productivity if the cycle time is 30 seconds.

💡 Hint: Pay attention to the difference between actual and optimum heights.

Question 2

Discuss how changes in the truck availability can alter the overall productivity of an excavation site and propose a management strategy to optimize machine scheduling.

💡 Hint: Consider how efficient truck scheduling can minimize idle times.
