1.3. Load Growth Curve

Try these first

1. 1.

   What is the definition of cycle time?

   Hint

   Think about what encompasses the entire operational process.

2. 2.

   What happens when a scraper is overloaded?

   Hint

   Consider the effect of filling the scraper bowl too full.

3. 3.

   What is the primary purpose of the load growth curve?

   • To maximize load capacity
   • To analyze loading efficiency
   • To measure vehicle speed

   Hint

   Think about what the curve represents in relation to performance.

4. 4.

   True or False: Diminishing returns occur when the scraper is loaded beyond 85%.

   • True
   • False

   Hint

   Recall the optimal loading percentage we discussed.

5. 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.

   Hint

   Consider what measurements would provide a direct link to operational efficiency.

6. 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.

   Hint

   Multiply the time saved by the number of scrapers and consider the cost implications.
