2. Pusher Cycle Time

Try these first

1. 1.

   What does LT stand for in the cycle time formula?

   Hint

   It's the first component in the cycle time formula.

2. 2.

   Define Dump Time.

   Hint

   Think of what happens at the end of the haul.

3. 3.

   What is ADBT in the cycle time formula?

   • Acceleration
   • Deceleration
   • and Breaking Time
   • Additional Brake and Deceleration Time
   • Acceleration
   • Direction
   • and Braking Time

   Hint

   Relate it to changes in speed.

4. 4.

   True or False: The loading time for scrapers is the same regardless of size.

   • True
   • False

   Hint

   Remember the role of the pusher.

5. 5.

   Evaluate how a 10% increase in load time impacts the overall cycle time if other components remain constant.

   Hint

   Think about how much heavier the load affects overall performance.

6. 6.

   Compare two scenarios: one with well-maintained haul routes and the other with poorly maintained routes. Discuss the differences in haul time and overall efficiency.

   Hint

   What specifics can you see affecting speed?
