Question 1.
What is the definition of cycle time?
Show hintHide hint
Think about what encompasses the entire operational process.
Question 2.
What happens when a scraper is overloaded?
Show hintHide hint
Consider the effect of filling the scraper bowl too full.
3Question 3.
What is the primary purpose of the load growth curve?
- To maximize load capacity
- To analyze loading efficiency
- To measure vehicle speed
Show hintHide hint
Think about what the curve represents in relation to performance.
4Question 4.
True or False: Diminishing returns occur when the scraper is loaded beyond 85%.
- True
- False
Show hintHide hint
Recall the optimal loading percentage we discussed.
Question 5.
Design a study on measuring the impact of haul route conditions on the efficiency of a fleet of scrapers. Include variables, methodology, and the anticipated outcome.
Show hintHide hint
Consider what measurements would provide a direct link to operational efficiency.
Question 6.
Calculate the potential savings by optimizing loading time for a fleet of scrapers, assuming each scraper's cycle is improved by 5 minutes per operation over 15 operations per day.
Show hintHide hint
Multiply the time saved by the number of scrapers and consider the cost implications.
