How to size a mining truck fleet: a decision framework.

Fleet size is not simply production divided by payload. Cycle time, availability, utilization, loading balance and operating variability change the answer.

Use this framework for discovery—not as a substitute for site engineering or OEM confirmation.

01 / DEFINE OUTPUT

Start with the production requirement.

Clarify material, target tonnes by period, working calendar, shifts, planned stops and the difference between average and peak demand.

02 / MODEL THE CYCLE

Break the cycle into observable parts.

Loading, loaded travel, dumping, empty return, queueing and delays should be estimated from site evidence and tested against variability.

03 / APPLY REALITY

Availability and utilization are not interchangeable.

Mechanical availability describes readiness; utilization describes productive use when available. Both require project-specific definitions and records.

04 / CHECK THE SYSTEM

Balance trucks with loading, roads and dumping.

A theoretical fleet count can fail if loaders, intersections, dumping capacity, road condition, refuelling or maintenance resources become bottlenecks.

05 / VERIFY

Run scenarios before committing.

Compare base, constrained and peak cases; document assumptions; obtain technical confirmation; and define how actual performance will be measured.
