4.1. Cycle Time Analysis

Try these first

1. 1.

   What is the back-track loading method?

   Hint

   Think about how the pusher moves after loading.

2. 2.

   Name one advantage of chain loading.

   Hint

   Does it have to go back like the back-track method?

3. 3.

   What is the slowest loading method?

   • Back-Track Loading
   • Chain Loading
   • Shuttle Loading

   Hint

   Think of how the pusher moves after loading.

4. 4.

   True or False: Chain loading eliminates backtracking.

   • True
   • False

   Hint

   Consider how the pusher operates after loading the first scraper.

5. 5.

   A construction site needs to calculate the productivity of scrapers operating under different loading methods. If scraper loading time remains constant at 4 minutes, analyze how the methods' cycle times affect overall production over an 8-hour shift.

   Hint

   Focus on understanding how each cycle time affects total time available.

6. 6.

   Given the average pusher takes 3 minutes per cycle, calculate how many scrapers can be effectively managed by one pusher if the loading time is established at 6 minutes using the balancing formula N = Ts/Tp.

   Hint

   Substitute into the formula for a clear understanding.
