Guide Rail Length Planning with hoistway travel height per rail of 410 ft: a worked example

This scenario runs the guide rail length planning calculation on the strong side: hoistway travel height per rail of 410 ft, with every other input held at its documented default. an estimator or installation planner needs a guide rail footage estimate for an elevator project

The inputs for this scenario

  • Hoistway travel height per rail: 410 ft (raised for this scenario; the documented default is 165)
  • Number of guide rail runs: 4 rail runs (unchanged)
  • Rail length unit conversion factor: 1 x (unchanged)
  • Cut, splice, and waste multiplier: 1.08 x (unchanged)

Working through the calculation

  • Applying the documented formula (Base rail footage before waste = hoistway rail height basis × guide rail runs × rail unit conversion) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,771 ft for required guide rail length, the number this scenario is built around.
  • At this operating point the engine returns 1,640 ft for base rail footage before waste.
  • At this operating point the engine returns 1.08 x for cut, splice, and waste multiplier.
  • At this operating point the engine returns 1,640 ft for rail height times rail runs.

How this compares with the baseline

  • Against the tool's baseline example, where hoistway travel height per rail sits at 165 ft and the headline result is 713 ft, this scenario comes in 148% above the baseline at 1,771 ft.
  • Use it during material take-off and procurement for a new installation or modernization, before issuing the steel purchase order. 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

  • Required guide rail length: 1,771 ft (headline result)
  • Base rail footage before waste: 1,640 ft
  • Cut, splice, and waste multiplier: 1.08 x
  • Rail height times rail runs: 1,640 ft
