Result Interpretation

Elevator Hoistway Width Sizer per ASME A17.1/CSA B44 Clearance Rules calculator computes Required Hoistway Width in m using the defined engineering formula and the input values provided. Required Hoistway Width is expressed in m. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Elevator Car Width = 1.4
  • Single-Side Guide Rail Clearance = 0.075
  • Single-Side Safety Buffer Zone = 0.15

Expected Result:

  • Required Hoistway Width = 1.85

Engineering Interpretation:

Under the given input conditions, the calculated result is: Required Hoistway Width = 1.85 m.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.

Formula / Method

required hoistway width = elevator car width + (2 * single-side guide rail clearance) + (2 * single-side safety buffer zone)

Required Hoistway Width.
