6. Balancing Scraper and Pusher Operations

Try these first

1. 1.

   Define cycle time in the context of scraper and pusher operations.

   Hint

   Think about the steps involved in using the scraper and pusher.

2. 2.

   What is one reason why balancing scraper and pusher operations is crucial?

   Hint

   Consider how idle machines affect productivity.

3. 3.

   What is the primary function of a pusher in earth-moving operations?

   • Loading material
   • Assisting scrapers
   • Operating independently

   Hint

   Think about the role each machine plays in a team.

4. 4.

   Cycle time refers to the total time taken for which process?

   • True
   • False

   Hint

   Consider all movements involved.

5. 5.

   A construction site has found that the pusher cycle time needs to reduce to enhance productivity. If currently, the scraper cycle time is 8 minutes and the target is to serve 7 scrapers, calculate the maximum pusher time feasible for balance.

   Hint

   Balance the equation step-by-step focusing on known variables.

6. 6.

   After analyzing operations, a project manager sees that running six scrapers reduces turnaround time; however, governing efficiency also demands higher operational costs. Evaluate how the project manager can justify this decision economically.

   Hint

   Every operational adjustment should relate to higher productivity initially outweighing costs.
