2. Conveyor corridor station 34+00 to 40+50
The average haul distance here is 400 feet. A 637D scraper has the following
cycle time:
Fixed time - 1 .1 minutes
Haul time (6% total resistance) .45 min.
Return Time (0% total resistance) 30 min.
Cycle Time 1.97TTF7.
With this cycle time, 637D scraper can move 702 CY per 50 minute work hour. A
total of 2,700 CY must be moved. Only one scraper could be assisted by one
D9L dozer with this short cycle time. Therefore, the following is the cost
for this portion of the operation.
1 - D9L dozer @ $144.29/hr. = $ 548.00
1 - D8L dozer @ $110.10/hr. = 418.00
1 - 637D scraper @ $208.79/hr. = 793.00
3 - Operators @ $54.00/hr. = 205.00
Total Cost $ 1,964.00
3. Bin bench and fill area
The average haul distance to the bin bench and fill area is 1 ,000 feet. A
637D scraper would have the following cycle time.
Fixed time 1 . 1 minutes
Haul time (6% total resistance) .80 min.
Return Time (0% total resistance) .50 min.
Cycle Time 2.4_m1n -
With this cycle dime two scrapers can be loaded by one D9L. A 637D ca
complete-18.5 cycles in a 50 minute work hour for a total of 481 CY/hr d
total-of 14,500 CY of topsoil must be moved. With two scrapers, the Sob o
be completed in 30 hours at the following cost: Z
