You are using a wheel loader (static tipping load of 14,800 lb) to load trucks from a stockpile of moist loam soil. The bucket size is 3 CY. The soil has a loose unit weight of 2,255 lb/LCY. The haul distance is 200 ft. The fixed time related to gear change and maneuvering is 0.7 minutes. The average speed of the loader when hauling the material is 3.5 mph and the average return speed is 7 mph. (a) Can the loader safely carry a full bucket load? (b) Estimate the production of the loader based on a 45 min/hour efficiency (c) What would be the production rate if the soil is blasted rock (fill factor=0.9; density= 3,300 lb/LCY)
