Port, Crane & Terminal Equipment worked example

Control Cabinet Assembly Time at 12% setup, handling, and delay allowance: a worked example

What does the result look like when setup, handling, and delay allowance reaches 12%? The full calculation is worked below with real intermediate numbers. Use it when control cabinet assembly time in port, crane and terminal equipment needs a defensible run time before a quote goes out.

The inputs for this scenario

  • Control cabinets to wire and build out: 120 units (unchanged)
  • Cabinets completed per minute (build rate): 12 units / min (unchanged)
  • Setup, handling, and delay allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base control cabinet assembly time = control cabinet assembly time workload รท control cabinet assembly time completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required control cabinet assembly time, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base control cabinet assembly time.
  • At this operating point the engine returns 12 % for control cabinet assembly time allowance applied.
  • At this operating point the engine returns 12 pieces / min for control cabinet assembly time completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where setup, handling, and delay allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • A figure at this level is achievable when setup, handling, and delay allowance is genuinely sustained, not just peaked for a shift. A single blended rate hides the gap between a simple relay panel and a fully-loaded VFD drive cabinet with hundreds of terminations.

Results at a glance

  • Required control cabinet assembly time: 11.2 hr (headline result)
  • Base control cabinet assembly time: 10 hr
  • Control cabinet assembly time allowance applied: 12 %
  • Control cabinet assembly time completion rate: 12 pieces / min
