1. A CAT D7H (power-shift) crawler is used in a pushing operation. The dozer is equipped with a straight blade. The material (dry and noncohesive) weighs 106 pcf in the bank state. It is estimated that the material will swell 7%, from bank to loose state. The center-of- mass-to- center-of-mass pushing distance is 300 ft on a 3% grade. The operators have average skill and the job will be performed in dusty visibility conditions. Job efficiency can be assumed to be equivalent to a 50- min hour. Calculate the production in bcy per hour.
