Result Interpretation

ISO 4301-1 & ISO 4308 Minimum Sheave Pitch Diameter for Steel Wire Rope calculator computes Minimum required sheave pitch diameter in m using the defined engineering formula and the input values provided. Minimum required sheave pitch diameter is expressed in m. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Nominal wire rope diameter = 0.012
  • Minimum sheave-to-rope diameter ratio (from ISO 4301-1 Table 2 & ISO 4308 Annex A) = 18

Expected Result:

  • Minimum required sheave pitch diameter = 0.216

Engineering Interpretation:

Under the given input conditions, the calculated result is: Minimum required sheave pitch diameter = 0.216 m.

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