2. Chain Loading Method

Try these first

1. 1.

   What is the main advantage of the chain loading method?

   Hint

   Think about how the scrapers and pushers interact.

2. 2.

   Name a situation where chain loading is preferable.

   Hint

   Consider the shape and design of construction sites.

3. 3.

   What method allows the pusher to reduce return time while loading scrapers?

   • Back-track loading
   • Chain loading
   • Shuttle loading

   Hint

   Think about the efficiency of each method.

4. 4.

   True or False: The back-track method is faster than the chain loading method.

   • True
   • False

   Hint

   Recall the characteristics of each loading method.

5. 5.

   In a construction project, a pusher has a cycle time of 1 minute, while a scraper load time is 2 minutes. How many scrapers can one pusher efficiently serve?

   Hint

   Apply the balancing formula correctly for your calculations.

6. 6.

   Evaluate the likely scenarios in contrast to chain loading and backtrack loading on a site requiring a minimum of 5 scrapers. Discuss productivity metrics.

   Hint

   Think about the implications of cycle times while contrasting the methods.
