Nominal Diameter – The Nominal Diameter is the diameter by which the rope is designated in a catalogue or on the Declaration of Conformity.

Reference Diameter – The Reference Diameter is the measured diameter of a section of rope that is not subject to bending, taken directly after running in the new rope. More simply this is the diameter of the rope when new and should be used as the baseline for uniform change in diameter.

Measured Diameter – The Measured Diameter  is the diameter that you  measure  as part of your examination  and should be assessed by taking the average of two measurements, taken at right angles to one another.

POSITION OF CALIPER

The Severity Rating represents the amount of deterioration expressed as a percentage towards discard . This rating may relate to either an individual mode of deterioration like decrease in diameter or the cumulative effect of more than one type of deterioration which might include visible  broken wires.


What is Wire Rope Diametric Reduction?

Over time, wire rope diameters decrease due to wear and tear. This reduction impacts the rope's strength and increases the risk of failure. The ISO 4309 standard establishes guidelines for measuring and assessing this diametric reduction to ensure safe operation.

 

How Does Our Calculator Help?

Our calculator simplifies the process of using the ISO 4309 standard. Simply enter the following:

  • Reference Diameter: The original diameter of your new wire rope.
  • Measured Diameter: The current diameter of your wire rope, measured at two perpendicular points.

The calculator will then calculate the percentage of diametric reduction and provide guidance on the remaining safe working life of your wire rope based on ISO 4309 benchmarks.

 

Benefits of Using Our Calculator:

  • Improved Safety: Make informed decisions about wire rope replacement, preventing accidents and equipment damage.
  • Enhanced Efficiency: Reduce downtime and maintenance costs by proactively managing your wire rope's lifespan.
  • Compliance with ISO 4309: Ensure adherence to industry standards for safe lifting operations.

Combined with Carl Stahl Evita's expertise in wire rope and lifting equipment, this calculator empowers you to confidently maintain the safety and performance of your lifting systems.
