How to use haul truck fleet sizing calculator
- Compare your result with the worked example.
- Check the assumptions and limitations.
WHEN IT HELPS
Common uses
- Size a preliminary truck fleet for a chosen production target while exposing availability and utilization separately.
Method and assumptions
Effective t/h per truck = payload × (60 / cycle minutes) × availability × utilization. Required trucks = ceiling(target / effective t/h).
Worked example
For 800 t/h, 60 t payload, 30 min cycle, 85% availability and 80% utilization, one truck supplies 81.6 t/h; 10 trucks are estimated.
Limitations
Cycle time should include loading, loaded travel, dumping, empty return and recurring delays without counting the same losses twice. Verify shovel matching, queueing and road constraints.
Frequently asked question
Why round fleet size up?
Truck counts are whole numbers. Rounding up avoids falling below the target in the mathematical estimate.
