Example 1 A wheel tractor-scraper weighing 100 tons
(91 t) is being operated on a haul road with a tire penetration of 2
in. (5 cm). What is the total resistance (lb and kg) and effective
grade when (a) the scraper is ascending a slope of 5%; (b) the
scraper is descending a slope of 5%?
A. Ascending (5%) :
Total resistance=9100kg
Effective Grade=10%
B. Descending (5%) :
Total resistance=0kg
Effective Grade=0%
Example 2 A crawler tractor weighing 80,000 lb (36 t) is
towing a rubber-tired scraper weighing 100,000 lb (45.5 t)
upa grade of 4%. What is the total resistance (lb and kg) of
the combination if the rolling resistance factor is 100 lb/ton
(50 kg/t)?
A. Ascending (5%) :
Total resistance=5535kg
