A Contractor is using a crawler CAT D7H dozer with straight blade. The dozer is operating on a loose stockpile material that weighs 2,250 lb/BCY with a swell factor of 0.75 from bank to loose state. The dozer is pushing 5,000 LCY of soil for 200 ft over downhill of 10% grade. The operator is of poor skill. The operator use slot dozing technique to improve productivity. The operational efficiency is estimated to be of 50-min hour. The figures below provide information about the dozer 1. What is the production in LCY/hr? 2. How long does it take for the dozer to finish the job?
