Fixture Loading Time at 29% rigging, alignment, and inspection allowance: a worked example

What does the result look like when rigging, alignment, and inspection allowance reaches 29%? The full calculation is worked below with real intermediate numbers. scheduling fixture capacity and material handling for heavy attachment builds

The inputs for this scenario

  • Fixture load and unload moves required: 36 units (unchanged)
  • Fixture handling pace: 5.5 units / hr (unchanged)
  • Rigging, alignment, and inspection allowance: 29 % (raised for this scenario; the documented default is 25)

Working through the calculation

  • Applying the documented formula (Base fixture handling time = fixture load and unload moves รท fixture handling pace) to the inputs above produces each figure below.
  • At this operating point the engine returns 8.44 hr for estimated fixture loading time, the number this scenario is built around.
  • At this operating point the engine returns 6.55 hr for base fixture handling time.
  • At this operating point the engine returns 29 % for rigging, alignment, and inspection allowance.
  • At this operating point the engine returns 5.5 moves / hr for fixture handling pace.

How this compares with the baseline

  • Against the tool's baseline example, where rigging, alignment, and inspection allowance sits at 25% and the headline result is 8.18 hr, this scenario comes in 3.2% above the baseline at 8.44 hr.
  • A figure at this level is achievable when rigging, alignment, and inspection allowance is genuinely sustained, not just peaked for a shift. It assumes a steady handling pace; one badly seated 1,200-lb coupler frame or a crane wait can blow past the allowance, so treat the result as a planning baseline, not a guarantee.

Results at a glance

  • estimated fixture loading time: 8.44 hr (headline result)
  • base fixture handling time: 6.55 hr
  • rigging, alignment, and inspection allowance: 29 %
  • fixture handling pace: 5.5 moves / hr
