6.2. Loading Time Consistency

Try these first

1. 1.

   What is back-track loading?

   Hint

   Think about how the process flows.

2. 2.

   Name one advantage of chain loading.

   Hint

   Consider the process speed.

3. 3.

   Which loading method is considered the slowest?

   • Back-Track Loading
   • Chain Loading
   • Shuttle Loading

   Hint

   Consider the need for return trips.

4. 4.

   True or False: Chain loading involves the pusher returning to get the next scraper.

   • True
   • False

   Hint

   Think about movement efficiency.

5. 5.

   A construction site uses back-track loading, with an average return time of 8 minutes and load time of 5 minutes. If they switch to chain loading, predict the potential time savings in completing a cycle.

   Hint

   Compare the total cycle times of both methods.

6. 6.

   If a project requires 100 loads and the pusher cycles every 3 minutes, how many scrapers would ideally be needed to keep up with this pace without delays?

   Hint

   Break down the problem into required cycles and the time taken.
