How the loader & haul truck matching calculator works

Passes are ceil(truck payload divided by loader payload per pass). A partly filled final pass still takes a full cycle. Loading time is passes times pass duration; full truck cycle adds away time, and continuous balance is full cycle divided by loading time.

Loader capacity is one payload per loading time. Fleet capacity is trucks times payload per full cycle. The lower continuous rate is multiplied once by system efficiency; whole balancing trucks round upward.

This is an ideal steady-state calculation, not a queue/dispatch simulation or guarantee of no waiting. No truck legality, loader rated capacity, haul-road condition or safe operating practice is determined.

Worked example

A 20-t truck at 5 t/pass needs four one-minute passes. With 20 minutes away, cycle is 24 minutes and continuous balance is six trucks. Five trucks at 80% system efficiency yield 200 t/h; six yield 240 t/h.

Sources and assumptions

The source material explains the underlying calculation or pricing structure. Entered prices, costs, schedules and scenario choices are your assumptions; this tool does not obtain supplier quotes or predict actual results.

  • Wheel Loader Productivity

    Relate loose bucket load, observed active cycle and a separate delay allowance to hourly output.

  • Material Stockpile Quantity

    Model a pile with a constant trapezoidal cross-section and vertical ends, then apply your bulk density and unit value.

  • Bucket Payload Estimate

    Combine nominal bucket volume, fill and loose density. Compare the estimated material mass with a limit you supply.

  • Earthmoving Truck Loads

    Apply an entered swell allowance to bank volume, then use both loose-volume and approved payload constraints.
