#5) Find the load time if a 2 LCY articulated wheel loader transfers average material from a stockpile to 18 CY trucks. Assume that volume controls and that travel time can be neglected. Assume that the average material fill factor is 90%and the loader production is at 100% efficiency #6) If a project has an estimated production of 400 LCY/hr., find the number of haulers needed (N) if the load time is determined to be 3 minutes and the truck...

(50) 7. Analyze the following operation. A 385C Excavator will be used to load material into a CAT 740 (no ejector) articulated truck. The excavator is equipped with a 6 cy heaped bucket and is capable of cycling every 30 seconds. The material being loaded weighs 3,300 lbs cy. The job efficiency is 90%. The trucks will be hauling the nmaterial 4000 feet over a road with a total rolling resistance of 9% to the dumpsite and 10% total rolling...
