You are using a CAT 6216 scraper for an earthmoving operation. The material to be hauled is a sandy-clay (dry earth) 1820 kg/m3. The expected rolling resistance for the well-maintained haul road is 30 kg/ton. The scraper loads in 0.85-min. This will result in an average load of 91 % heaped capacity. The maximum safe driving speed is limited to 55 km/h. To account for both acceleration and deceleration use an average speed of 8km/hr over a distance of 60m. Use a 55-min hour efficiency factor. The total length of haul is 1000m and has the following individual segments when moving from cut to fill: a 400m +8%grade load factor = 0.82 600m +3% grade heaped Capacity = 15 m 200m 0%grade Rated Load =23,950kg Dump time = 0.3 minute Calculate the haul and return time for the scraper and its total cycle productivity.
