1. Cycle Time of a Scraper

Try these first

1. 1.

   What does LT stand for in cycle time?

   Hint

   Think about the time it takes to load the scraper.

2. 2.

   Which component of cycle time is influenced by distance?

   Hint

   Consider the time spent traveling.

3. 3.

   What does ADBT stand for?

   • Accelerate
   • Decelerate
   • Brake Time
   • Accelerate
   • Decelerate
   • Bypass Time
   • Accelerate
   • Dismantle
   • Brake Time

   Hint

   Think of common terms used in motion.

4. 4.

   True or False: Loading time is consistent regardless of scraper size.

   • True
   • False

   Hint

   Consider the role of the pusher.

5. 5.

   Determine the impact on cycle time if the loading time is increased by 0.5 minutes due to poor material conditions.

   Hint

   Think about how often loading occurs in a cycle.

6. 6.

   Calculate the optimal loading percentage if data shows that loading increases time significantly beyond 85%.

   Hint

   What does the data say about performance degradation?
