Aggregate Loader Cycle Rate at 94% loader operating efficiency: a worked example

This scenario runs the aggregate loader cycle rate calculation on the strong side: 94% loader operating efficiency, with every other input held at its documented default. a loader operator or plant manager needs to verify stockpile-to-bin feed capacity for aggregate or RAP

The inputs for this scenario

  • Loader bucket cycles per hour: 42 cycles / hr (unchanged)
  • Aggregate per bucket: 5.5 tons / bucket (unchanged)
  • Loader operating efficiency: 94 % (raised for this scenario; the documented default is 82)

Working through the calculation

  • Applying the documented formula (Gross loader feed rate = loader bucket cycles × aggregate per bucket) to the inputs above produces each figure below.
  • At this operating point the engine returns 764 tons / hr loaded for rate, the number this scenario is built around.
  • At this operating point the engine returns -670 points for gap to target.
  • At this operating point the engine returns 42 count for affected count.
  • At this operating point the engine returns 5.5 count for total count.

How this compares with the baseline

  • Against the tool's baseline example, where loader operating efficiency sits at 82% and the headline result is 764 tons / hr loaded, this scenario lands almost exactly on the baseline at 764 tons / hr loaded.
  • Use it when checking whether a loader can keep a plant fed, sizing a loader for a new plant, or benchmarking operator productivity against a target. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Rate: 764 tons / hr loaded (headline result)
  • Gap to target: -670 points
  • Affected count: 42 count
  • Total count: 5.5 count
