Based on the scraper specifications in Table 8.1 and on the "performance charts" in Figs. 8.9 and 8.10, and for haul conditions as stated here, analyze the probable scraper production. How many scrapers would be used and what will be the production m bey per hr? The maternal to be hauled is a sandy clay (dry earth), 2,800 lblbcy. The expected rolling . resistance for the well-maintained haul road is 40 lblton. Use a O.85-mm load time. This will result in an average load of 91 % heaped capacity. To account for both acceleration and deceleration use an average speed of 5 mph over a distance of 200 ft. Use a 50-min hour efficiency factor. The total length of haul is 3,200 ft and has the following individual segments when moving from cut to fill:
