2.2. Cost Calculation for 6 Scrapers

Try these first

1. 1.

   What is the volume per load of the scraper?

   Hint

   Look for the information about volume in the text.

2. 2.

   Define cycle time in the context of scrapers.

   Hint

   Consider loading, transporting, and unloading.

3. 3.

   What is the estimated productivity when using 5 scrapers?

   • 636.89 bank cubic meters/hour
   • 723.36 bank cubic meters/hour
   • 500 bank cubic meters/hour

   Hint

   Refer to the productivity section for specifics.

4. 4.

   True or False: The use of 6 scrapers results in a lower production cost.

   • True
   • False

   Hint

   Compare the unit costs for both scenarios.

5. 5.

   Given that using 5 scrapers results in significant idle time, argue for or against increasing the number of scrapers in terms of overall project efficiency and costs.

   Hint

   Consider the trade-offs between productivity demands and financial constraints.

6. 6.

   Calculate the total cost over a specified period if you use 5 scrapers for 10 hours per day versus 6 scrapers for 10 hours per day. Which approach is more cost-effective?

   Hint

   Add productivity with unit costs over the total operational timeframe.
