6.3. Optimal Loading Time

Try these first

1. 1.

   What is Back-Track Loading?

   Hint

   Think about the travel involved after loading.

2. 2.

   Name one advantage of Chain Loading.

   Hint

   Consider how scrapers are positioned.

3. 3.

   Which loading method is the slowest?

   • Back-Track Loading
   • Chain Loading
   • Shuttle Loading

   Hint

   Think about the return times needed for this method.

4. 4.

   True or False: Chain Loading involves the next scraper waiting near the pusher.

   • True
   • False

   Hint

   Consider how this method operates.

5. 5.

   Given an optimal loading time of 8 minutes for a scraper, calculate the pusher cycle time. Also, discuss how this affects overall project scheduling.

   Hint

   Apply the formula carefully and analyze how changes in Tp can influence project outcomes.

6. 6.

   In a project setup, you have 4 scrapers and 1 pusher. Calculate if the current setup is optimal if the cycle time for the scrapers is 25 minutes.

   Hint

   Consider how many scrapers one pusher can serve effectively to minimize waiting times.
