Challenge Problems
Push your limits with challenges.
Question 1
A scraper operates at an altitude of 600m with a coefficient of traction of 0.6, and the gross weight is 80,000 kg. Calculate the maximum rimpull and the rimpull after altitude adjustment.
💡 Hint: Remember to apply the altitude deduction after calculating initial rimpull.
Question 2
Discuss how to effectively plan a scraper operation in a region with a 5% gradient considering altitude effects and necessary adjustments.
💡 Hint: Consider both initial rimpull calculations and adjustments needed for expected site conditions.
