Bucket fill factor table
WebSolution: Bucket fill factor (average) = 0.95 (From table) Bucket load = 0.75 x 0.95 = 0.71 LCY Job efficiency = 50 / 60 = 0.833 Production = volume/cycle x cycles/h (include efficiency) = LCY/h1060.833x203600x0.71 Time required = h4.7106500 WebUse Tables 9.4 and 9.5 to find the bucket fill factor and cycle time. If a range is given, use the average value. The exchange time is 0.60, 0.80, 1.00, and 1.20 min. respectively for the four trucks. The material is being hauled to a fill located 4.0 miles away. The trucks average 30 mph during the haul and 40 mph during the return.
