A project consists of replacing the track on an existing railroad line, involving 3,000 feet oftrack. The old track can be removed at a rate of 70 feet per hour. The old railroad ties can beremoved at a rate of 200 feet (measured along the track) per hour. The new ties can be installedat a rate of 25 feet per hour and the replacement track can be installed at a rate of 40 feet perhour. Show this operation on a linear schedule. Assume that the minimum float for an activity atany location is one day

You need to rip a field that is 780 feet wide and 230 feet long to a depth of 11 inches. The dozer is working at a speed of 0.9 mph and it takes 24 seconds to turn and reengage the rippers. If the dozer is making its passes in the "Tength" direction and can reach the full required depth with each pass, determine how many hours it will take to rip the entire field If the width between passes is 41 feet Use a 50 minute work hour. Round your answer to 1 decimal place. Only fill in numeric values with no units.

3. A portable conveyor system is used to load wet sand from a stockpile to a concrete mix plant. The conveyor has a 30" wide belt that has a travel speed of 300 feet per minute. The angle of repose for the sand is 15°. Compute the average production rate of the conveyor in cubic yards per hour.
2. Determine the balanced hauls and indicate the direction of haul for the mass diagram shown below. The LPH is 4,000 ft. Also, show on the profile what cut sections will be hauled to what fill sections, and indicate any borrow or waste sections. Calculate the average haul distance for each. balanced haul.. 75000 50000 25000 0 -25000 -50000 -75000 0 Distance along centerline, ft 14000 15000
7. A hydraulic shovel will be used to excavate sandy clay and load it into a 12 BCY dump truck. The shovel production at 100% efficiency is estimated to be 300 BCY/hour and job efficiency is 0.80. Truck travel time is estimated to be 8.0 minutes and truck fixed cycle time (excluding loading) is estimated to be 2.0 minutes. Equipment costs for the shovel and trucks are $40/h (shovel) and $20/h (truck). A. How many trucks are theoretically required to obtain maximum production? B. What is the expected production of the system in banked measure using this number of trucks? C. What is the expected unit loading and hauling costs in $/BCY?
Estimate the volume of the earth that has to be removed to make room for the 96 km, 7 m diameter, concrete-lined water tunnel. Also, investigate the capacity of typical dump trucks used in removal of earth materials. P R O B L E M Copyright
Chapter 8 SCRAPER CYCLE TIME (See ppg. 236-244) Determine the cycle time for a single-engine scraper rated at 21 cy heaped that is used to haul material from a pit to a fill 900 ft away under severe conditions. The average haul speed will be 14 mph The average return speed will be 20 mph Assume, at an average speed of 5 mph that 200 ft is required to both accelerate and decelerate. The operating efficiency will be equal to a 50-min hour. It will take 0.80 min to load this scraper. distance,ft 88 conversion factor = = Time, min. speed,mph x 88 Distance, ft.
