2.1. Introduction to Chain Loading

Try these first

1. 1.

   What is back-track loading?

   Hint

   Think about the travel involved in this method.

2. 2.

   Name one advantage of chain loading.

   Hint

   Consider how it saves time in operations.

3. 3.

   What is the primary benefit of chain loading?

   • Longer cycle times
   • Reduced wait time
   • Increased backtracking

   Hint

   Consider the workflow of scrapers and pushers.

4. 4.

   True or False: Back-track loading has a shorter cycle time than chain loading.

   • True
   • False

   Hint

   Think about how backtracking affects time.

5. 5.

   If a project site requires 5 scrapers to be served by 1 pusher with an average scraper loading time of 10 minutes, calculate the ideal cycle time using the formula provided.

   Hint

   Apply the formulas correctly to find the relationship.

6. 6.

   In a scenario where back-track loading causes delays, propose a chain loading strategy that could replace it, detailing the expected improvements in cycle time.

   Hint

   Analyze workflow and think about material flow.
