Case Study Of Earthmoving by Using Um-cyclone

Loaders Used in Simulation ModelCAT 936CAT 950E Machines available21 Bucket Size (m 3 )22.4 Soil loaded in loader’s bucket, S (m 3 ) Bucket Size* N[1,0.05] Bucket Size * N[1,0.04] Time to load a scoop of soil in truck (min) 0.40+0.05S0.43+0.035S Cost (\$/hr)4562

Truck Equipment That Used. ModelCAT 769CCAT 773B Machines available83 Capacity (m 3 )23.634.1 Max. speed (km/hr)7562 Actual speed (km/hr) Calc. Speed *N[1,0.03] Calc. Speed *N[1,0.02] Dumping time (min)11.12 Maneuvering time at loading area (min) 0.60.72 Cost (\$/hr)117175

Result of Cyclone  The total time that required moving 200,000 m 3 based on 3 loader and 11 trucks is 19128.7 minute = 318.8 hours = 45.5* working days. *Assuming 7 hours/day.  Cyclone software. Cyclone software
