Problem
A CAT D7H (power-shift) dozer 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 downhill on a 3% grad& The operators have average skill and the job will be performed in dusty conditions. lob efficiency can be assumed to be equivalent to a 45-min hour.
