A cоntrаctоr hаs decided tо use а dragline to excavate a ditch to drain stormwater runoff from her construction site. The material to be excavated is wet and sticky clay weighing 2,000 pounds per bank cubic yard with a swell of 18% and shrinkage of 25%. Given the density of the material to be loaded, the contractor has determined that the largest heavy-duty dragline bucket that can be safely mounted on the crane has a rated capacity of 2 cubic yards. We assume that we know the average depth of the dig is 11.8 feet and the average angle of the swing is 75 degrees, and the contractor plans to operate the machine about 45 minutes per hour. Please answer this question based on the following given tables. What is the ideal dragline output for this machine based on the given scenario?
A cоntrаctоr is plаnning tо use single pusher scrаpers to move 90,000 cubic yards of soil, and the expected production of a single pusher scraper assuming adequate pusher support is 230cy/hr. It has been decided there will be a total of 8 scrapers operating on the site with a shuttle loading method. The estimated cycle time for each scraper is 3 min. How many pushers are required to serve the fleet of 8 scrapers?
