Bulk Solids, Mining, Aggregates & Material Processing worked example

Truck Loadout Time at 8.64% spotting, weighing and tarping allowance: a worked example

This worked example runs the truck loadout time numbers for a tougher week than the baseline: 8.64% spotting, weighing and tarping allowance instead of the typical 12%. Estimate truck loadout time for truck loadout time for bulk solids, mining, aggregates, and material processing using plant-floor material, production, quality, capacity, or cost inputs.

The inputs for this scenario

  • Tonnage to load into the truck: 1,200 tons (held at the documented default)
  • Loadout conveyor or chute fill rate: 150 tons / hr (held at the documented default)
  • Spotting, weighing and tarping allowance: 8.64 % (the input this scenario stresses; the baseline uses 12)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base truck loadout time = truck loadout time workload รท truck loadout time completion rate.
  • Truck Loadout Time works out to 8.69 hr at these inputs, and this is the headline figure for the scenario.
  • Base truck loadout time works out to 8 hr at these inputs.
  • Truck Loadout Time allowance works out to 8.64 % at these inputs.
  • Truck Loadout Time completion rate works out to 150 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where spotting, weighing and tarping allowance sits at 12% and the headline result is 8.96 hr, this scenario comes in 3% below the baseline at 8.69 hr.
  • Use it when scheduling truck appointments, sizing a queue lane, or quoting a turnaround time to a haulage customer. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Truck Loadout Time: 8.69 hr (headline result)
  • Base truck loadout time: 8 hr
  • Truck Loadout Time allowance: 8.64 %
  • Truck Loadout Time completion rate: 150 pieces / min

Run it with your numbers

  • To rerun this with your own numbers, open the live Truck Loadout Time calculator, set spotting, weighing and tarping allowance to your actual value, and adjust the remaining inputs to match your operation.
