Points A scraper is operating on an earthen road and has penetration of 2.5 in. This scraper has an EVW of 90,000 lb and its GVW is 170,000 lb. The grade from cut to fill is 3%. Calculate the total resistance in both pounds and equivalent grade and also use Using the performance chart given on slide 32 (Numerical Example 1 Equipment Power) determine the speeds
A scraper [low pressure rubber tires] is working on a road that is earth (compacted & maintained) as a haul road. The grade of the road is 2.5 % (cut to fill). Weight of vehicle is 98000 lb. Weight of soil to be hauled is 70000 lb. Calculate the total resistance that the scraper must overcome.
