How to use excavator productivity calculator
- Compare your result with the worked example.
- Check the assumptions and limitations.
WHEN IT HELPS
Common uses
- Use this excavator production estimate to compare equipment and plan loading operations. The result describes loose material handled per productive hour under your assumptions.
Method and assumptions
Cycles/h = 3,600 / cycle seconds × efficiency. m³/h = cycles/h × bucket m³ × fill factor. t/h = m³/h × loose bulk density.
Worked example
A 2.5 m³ bucket, 90% fill, 30-second cycles and 75% efficiency produces 202.5 m³/h. At 1.8 t/m³ the estimate is 364.5 t/h.
Limitations
Capacity is loose-volume capacity, not in-situ bank volume. Do not mix swell and density bases. Spotting, queueing, truck availability and haulage can constrain real output.
Frequently asked question
Does excavator capacity equal mine production?
No. Actual mine production may be limited by hauling capacity, delays, material conditions and operational constraints.
