100,000 yd³ of embankment material to compact.
815 can do 616 yd³/hour (4-passes) (4mph) (6-inch lifts) *
2000 can do 2,600 yd³/hour (4-passes) (7mph) (6-inch lifts)
Yes the Impactor 2000 can do thicker lifts. We'll get to that in a second.
815 will take 162-hours to do the job.
2000 will take 39-hours to do the job.
815 takes about 10-gallons of fuel per hour.
2000 takes about 6-gallons of fuel per hour. (Being towed by
a John Deere 4840)
815 = 162-hours x 10-gallons = 1,620 gallons fuel/hour to accomplish
2000 = 39-hours x 6-gallons = 234 gallons fuel/hour to accomplish
The IMPACTOR 2000 uses 1,386
fewer gallons than the Caterpillar 815.
above was calculated with the Impactor 2000 compacting 6" lifts.
Often the Impactor 2000 may produce the required results while compacting
24-inches or more at a time. In this case the job could be completed
in as few as 10-hours. In which case the fuel
saving may be as high as 1,561 gallons for this job.

example shown above, the job may be performed by the IMPACTOR 2000 in
as little as 10
man-hours as opposed to the 162 man-hours required by the Caterpillar
The IMPACTOR 2000 requires 152
fewer man-hours than the Caterpillar 815. Multiply that
times you're operator's wage.
