An excavator bucket has a heaped capacity of 6.2 CY and a bucket fill factor of 0.85. What is the bucket capacity?a. 5.35 CY b. 6.1 CY c. 7.3 CY d. 5.27 CY
In a truck and shovel operation, the time for a truck to position itself at the shovel and be loaded are 0.50 minute and 3 minutes respectively. It then takes the truck 10 minutes to haul the ore, dump it at the coarse ore bin, and return to the shovel. How many trucks do you need to keep the shovel busy with a little waiting time for the trucks?
A hydraulic excavator with a 2 cubic yard heaped capacity bucket is excavating in common earth. The depth of the excavation is 8 feet. The excavator has a maximum rated digging depth of 16 feet. The excavated material will be positioned so that the swing angle is 75 degrees. The job efficiency is 55 minutes per hour. Find the expected production per hour.

A contractor plans to buy a backhoe machine for a construction project. The total useful hour of the machine is estimated to be 6 years with 9,000 hours of use. He estimates the unit cost to be $2.82/CY. If the backhoe has to excavate 2,000 CY of soil, what is the total cost for this operation? $5,640 $25,380 $54,000 $12,000
A contractor has a contract to construct a 12,000-ft-long tunnel in 30 months. He is trying to decide whether to do the job with his own forces or subcontract the job. He asks you to calculate the equivalent monthly cost of each alternative. His i = 1 percent per month. Production under both alternatives will be 300 ft per month. Alternative A Buy a tunneling machine and work with contractor's own forces. cost of tunneling and machine = $ 2,400,000 paid now salvage value of machine at EOM 30 = $ 540,000 cost of labor and materials = $ 250/ft for the first 10 months, increasing by 0.5%/month at EOM each month thereafter Alternative B Subcontract the work. Cost $500 per foot of advance of the tunnel heading, for the full 12,000 ft. %3D
