Yоu аre using а bаckhоe excavatоr for foundation excavation. The rated struck capacity of the bucket is 2.5 CY. The type of soil is sand. The fill factor is 1.05. The soil consists of less than 25% of rock content. Depth of excavation is 50% of the machine’s maximum digging depth and the swing angle is less than 60 degrees. The operational efficiency of the backhoe is 50 min/hr. The excavated materials are loaded into dump trucks with heaped capacity of 25 LCY. The cycle time of a truck is 16 minutes. You can use Table 11.6 to determine the cycle time for this backhoe excavator. (a) What is the hourly production of the excavator?(b) How many trucks do you need?(c) Using the number of trucks obtained in part (b), how would the hourly production of the operation change if the cycle time of the trucks changes to 26 minutes due to traffic on the haul road (no calculations required for this part– just explain how would the change impact the production)
