3.3. Correlating Rimpull with Horsepower

Try these first

1. 1.

   What is the maximum production output with five scrapers?

   Hint

   Remember the calculations presented for five scrapers.

2. 2.

   What does rimpull refer to?

   Hint

   Think about where the wheels meet the ground.

3. 3.

   What is the production of five scrapers per hour?

   • 636.89 bcm
   • 723.36 bcm
   • 500 bcm

   Hint

   It was mentioned as part of the initial calculations.

4. 4.

   True or False: Increasing the number of scrapers always increases production efficiency.

   • True
   • False

   Hint

   Consider the balance of productivity vs costs.

5. 5.

   For a scraper at 600m altitude with given coefficients, calculate the effective rimpull in different gears after corrections. Discuss whether the machine should continue functioning in the top gear.

   Hint

   Focus on your calculations regarding coefficients and weight adjustments.

6. 6.

   In a scenario with competitive projects, analyze the implications of choosing five versus six scrapers from an efficiency and cost perspective and suggest an ideal combination.

   Hint

   Review what was said about project deadlines and cost concerns.
