A hydrаulic excаvаtоr (crawler mоunted) will be expected tо excavate material that has been characterized as sand. The excavator has a bucket capacity of 3 CY. The manufacturer specifies the maximum depth that it can cut = 18 ft. The supervisor estimates that the average depth of excavation will be 12.5 ft. The excavator operator expects that the dump trucks will be located such that the angle of swing would be 180 degrees. The system efficiency can be expected to be 40 minutes per hour. By adjusting the location of the excavator it would be possible to change the angle of swing to 120 degrees. Calculate the % increase in production if all other factors remain the same.
