3. Shuttle Loading Method

Try these first

1. 1.

   What is back-track loading?

   Hint

   Think about how the pusher moves after each load.

2. 2.

   What is the cycle time?

   Hint

   Consider how long the entire process takes.

3. 3.

   What is the primary disadvantage of back-track loading?

   • Quick returns
   • Increased cycle time
   • High efficiency

   Hint

   Think about the extra steps involved.

4. 4.

   True or False: Shuttle loading is effective only when there is a single fill area.

   • True
   • False

   Hint

   Recall where shuttle loading is applied.

5. 5.

   A construction site has 5 pushers and 15 scrapers. If each pusher can only handle 3 scrapers due to cycle time issues, what would you recommend to optimize productivity?

   Hint

   Think about the relationship between the number of scrapers and pushers.

6. 6.

   Using the provided cycle time formula, if Lt is increased to 7 minutes, what will be the new cycle time for the pusher?

   Hint

   Substitute the new loading time into the established formula.
