3.1. Rimpull Sufficient Analysis

Try these first

1. 1.

   Define rimpull.

   Hint

   Think about what enables the scraper to move its load.

2. 2.

   What does cycle time represent?

   Hint

   It includes loading, transporting, and unloading time.

3. 3.

   What is the relationship between the number of scrapers used and their productivity?

   • Inversely proportional
   • Directly proportional
   • Unrelated

   Hint

   Think about how more resources affect work output.

4. 4.

   Rimpull is defined as what?

   • True
   • False

   Hint

   Consider what ability rimpull grants to the machinery in operation.

5. 5.

   Given a project at 600 meters altitude requiring sufficient rimpull from a scraper with a total weight of 76,000 kg, calculate the effective rimpull after applying altitude corrections.

   Hint

   Start by calculating the maximum rimpull and then apply the altitude correction.

6. 6.

   Analyze a scenario where using six scrapers provides higher productivity but higher unit costs. How would you decide on the best configuration?

   Hint

   Evaluate the metrics of both productivity and costs comprehensively to arrive at an informed conclusion.
