total loader cost/hr. - tiyv
$ o r /hr. divided by _�_ shifts/day = $ average truck cost/hr.
divided by shifts/day = $ i yo.&4 average loader cost/hr.
MATERIAL QUANTITIES:
Bank volume = BCY x swell factor = 806 -;z LCY
Verification method(s) used /h-✓ —G-��°L•
HOURLY PRODUCTION:
Haul distance =S-a 8 c, ft. , return distance = ft. , altitude = ' ft.
Total resistance au � % rolling res. plus h grade res. +or- _ p %
Total resistance (return): rolling res, plus grade res. (+or-)= _7 $
Note: for grade resistance, (+) = unfavorable, favorable (downhill )
Truck capacity LCY (nominal heaped)
Loader capacity = LCY (nominal heaped) x /o o bucket fill factor from
fill factor adjustment table in Section VII = LCY/bucket load (adj. cap'y)
No. of loader passes required to fill truck = = (round to nearest whole no.)
Adjust truck capacity = 3o ? LCY
Loader cycle time: basic cycle (load, maneuver and dump) = min.
1st pass = 0.1 min (bulk of 1st pass completed cfuring truck exchange time)
