What is the approximate optimum hourly production rate for a wheeled backhoe filling hauling units? Struck capacity for the bucket is 6 loose cubic feet and the bucket fill factor is 110%,. The cycle time is 2 minutes, the soil type is moist loam with a 25% swell factor.
A project to move packed earth requires you to decide whether to usea dozer/scraper operation or excavator/truck operation. Determinethe most economical operation based on the dozer/scraper operationestimated at $1.25/cy. All equipment carries a rated heaped capacity, hasa fill factor of 100%, and works 45-min hours. Excavator costs $95/hr（including operator), cycle time is 0.28 min, and bucket heaped capacityis 5.0 cy. Truck costs $150/hr.(including operator), dump time is 0.5 min（maneuver, dump, turn), heaped capacity is 31.7 cy, and 12 trucks areavailable for the project.Hauling equipment operates in one directionfrom A to B to C and finally to D.

A loader operating at 107 cy/hr has 2.5-cy heaped capacity bucket and has a 1.2-min load cycle. The trucks have 11-cy capacity and a 30-minute dump + haul + return time. A 95% fill factor applies to the loader. The project works 50-minute hours. Determine the job production for 7 trucks. A 94.70 cy/hr B 95.55 cy/hr C 93.70 cy/hr D 96.70 cy/hr
It is determined that a 5-m width-of-cut combine is traveling 1.5-m/s.

75. A 4-ha field was plowed using a three-bottom 12-inch tractor-mounted moldboard plow. It took 11 hrs. to complete the operation at a tractor speed of 5 kph.Find the theoretical field capacity:a. 0.46 ha/hr b. 1.45 ha/hrc. 1.13 ha/hr d. 1.8 ha/hr
a. Assuming that each load is a full-capacity load, howmany truckloads are required to construct the fill?b. What should be the volume of the pit that remains in theborrow area after all the material required for the fill hasbeen removed?c. How many liters of water will have to be added per truckload,assuming that the moisture lost by evaporation duringexcavation, haulage, and handling is negligible?d. If the fill should become saturated at some time subsequentto the construction and does not change volumeappreciably, what will be its saturation water content?
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 900ft 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 200ft 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.
Calculate the total operation time for this construction activity if the volume of soil to be removed is 8 cu.m. (considered 33% for bulking of materials.) The speed of dumptruck is 30 kph and travel distance (round trip) from the source to disposal area vice-versa is 6 km. The bucket size of excavator is 0.50 cu.m at 0.50 min loading time, tipping time is 4 mins. a. 15.18 minutes b. 22.02 minutes c. 25.32 minutes d. 30.00 minutes
