A construction site requires excavating to a depth of 4 meters. If the optimum height of cut is 6 meters, and the truck is at a 60-degree angle swing, calculate the expected productivity correction factor.
💡 Hint: Refer back to your resources for the correction factor table.
Two backhoes are scheduled for use, but one operates with an angle of swing averaging 120 degrees. If we assume their cycle times are significantly affected, estimate the time difference in loading trucks relative to an ideal 90 degrees.
💡 Hint: Remember the impacts of swing angle on productivity described in the section.
