The formula is as follows:
Q = (60_q_z_n_kf) / kl
, where Q is the productivity of the excavator, q is the capacity of each rotor bucket in cubic feet, z is the number of buckets on the wheel and n is the speed of rotation of the rotor, measured in revolutions per minute.
How is excavator bucket volume calculated?
We all know that the volume is calculated by
multiplying Width x Height x Length or Area of the end x Length.
How many cubic yards can an excavator dig in a day?
1/2 Yard bucket, one cycle every 30 seconds = 120 cycles or 60 yards per hour X (6) productive hours =
360 yards
excavated per day.

14 feet
.
How do I know my excavator capacity?
Divide the per cycle payload
(6.67 tons) by the material density (1.25 tons/cu. yd.) to determine the nominal bucket capacity: 6.67 / 1.25 = 5.28 cu yds.
What is bucket fill factor?
Fill Factor is
the percentage of an available volume in a hauler body, bucket or bowl that is actually used
. For example, a fill factor of 87 percent for a hauler body means that 13 percent of the rated volume is not being used to carry material. Buckets often have fill factors over 100 percent.
How wide is an excavator bucket?
Up to 0.75-ton machine: Bucket widths of
6 inches to 24 inches
, or 30-inch grading buckets. 1-ton to 1.9-ton machine: Bucket widths of 6 inches to 24 inches, or grading buckets 36 inches to 39 inches. 2-ton to 3.5-ton machine:Bucket widths of 9 inches to 30 inches, or 48-inch grading buckets.
How much fuel does a mini excavator use per hour?
Under a normal workload the excavator should use
approximately 12 gallons per hour
. Under medium load factor, its consumption increases to around 2.6 to 3.1 GPH and when the load is to its maximum, the fuel consumption is 3.1 to 3.8 GPH.
How many hours is a lot on a mini excavator?
Mini-excavators typically offer a similar average lifespan of
around 10,000 hours
. For both excavators and mini-excavators, you’ll want to pay special attention to the undercarriage wear and the condition of the tracks.
Can a mini excavator remove stumps?
Yes
, you can remove tree stumps with a mini excavator, but of course, there is a limit to how big a tree stump it can remove. For smaller stumps, a mini excavator can simply pull it out. For larger stumps, you may need special attachments for mini excavators.
How is earth work calculated?
To calculate the earthwork estimate requires multiplying the area by the difference between the average of two sets of levels. Formula:
Volume = Area * Difference between the average of two sets of levels
.
How do you price an excavation?
A typical residential excavation job runs
between $1,445 and $5,267 with an average of $3,253
. Though most companies charge anywhere from $40 to $150 an hour, residential jobs receive project bids. Project bids reflect cubic yards of dirt moved, anywhere from $50 to $200 per cubic yard.
