Question 1.
What does ADBT stand for in the cycle time equation?
Show hintHide hint
Think about what happens when a vehicle speeds up or slows down.
Question 2.
What is the primary reason for maintaining haul routes?
Show hintHide hint
Consider what factors might slow down a vehicle.
3Question 3.
What defines the variable components of cycle time?
- Depends on site speed
- Does not change with distance
- Includes dumping time
Show hintHide hint
Think about how distance affects time taken.
4Question 4.
True or False: Pushing scrapers to maximum load always increases efficiency.
- True
- False
Show hintHide hint
Remember the loading growth curve discussed.
Question 5.
Analyze a loading curve where initially the load is increased but the loading rate decreases after reaching 85%. How would this affect operational costs?
Show hintHide hint
Think about the efficiency each loading can provide.
Question 6.
A project manager reports that the haul route is poorly maintained. Calculate the potential impact on cycle time for a project with 10 scrapers working. Assume each scraper experiences a slowdown of 20%.
Show hintHide hint
Quantify the impact based on a standard cycle time.
