7.1. Summary of Key Points

Try these first

1. 1.

   What is the main characteristic of back-track loading?

   Hint

   Think of the term 'back-track'.

2. 2.

   Which loading method is recommended for long, narrow cuts?

   Hint

   Consider where you might see this method—like a road.

3. 3.

   What is the slowest loading method discussed?

   • Back-track Loading
   • Chain Loading
   • Shuttle Loading

   Hint

   Remember which method has to go back after loading.

4. 4.

   True or False: Chain loading requires the pusher to return to the previous scraper after loading.

   • True
   • False

   Hint

   Consider how chain loading operates.

5. 5.

   If a pusher has a cycle time of 5 minutes and the loading time for a scraper is 10 minutes, how many scrapers can be efficiently serviced by this pusher?

   Hint

   Make sure to distinguish between the loading times.

6. 6.

   Consider a construction site needing to move materials in both directions. Describe how implementing shuttle loading could improve operation efficiency compared to back-track loading.

   Hint

   Reflect on the dynamics of loading in both scenarios.
