5. Cycle Time Calculation

Try these first

1. 1.

   What is back-track loading?

   Hint

   Think about what happens to the pusher once the scraper is loaded.

2. 2.

   Which loading method reduces return time by having scrapers wait near the pusher?

   Hint

   Recall the method that allows the next scraper to come to the pusher without backtracking.

3. 3.

   What is the slowest loading method?

   • Back-Track
   • Chain
   • Shuttle

   Hint

   Think about which method requires the most travel time for the pusher.

4. 4.

   True or False: Chain loading involves scrapers waiting near the pusher.

   • True
   • False

   Hint

   Recall how scrapers are positioned in this method.

5. 5.

   If a pusher has a cycle time of 10 minutes and serves 5 scrapers equally, what is the cycle time for each scraper?

   Hint

   Division will help you find the cycle time attributable to each scraper.

6. 6.

   In a construction project, if the loading time is 8 minutes for a scraper, calculate the pusher cycle time. Also, explain the significance of this in project planning.

   Hint

   Plugging the loading time into the equation will guide you to the answer.
