Wire rope calculator


Wire ropes are a ubiquitous part of almost everything you see around you every day. They can be found in cars, boats, planes, trains, buildings, cranes, winches, rigging, guard rails, bridges, flexible pipes, etc., all around the world.

They make excellent tensile structural members (take a look in most modern airport terminal buildings) in that they can support much higher tensile loads than any plain steel beam of a similar cross-sectional area and tolerate much larger assembly tolerances.

The wire rope calculator determines the expected properties of multi-strand cables based upon the effects of increased packing density and dimensional changes under tension.

The nature of these products renders them difficult to calculate accurately. Only controlled testing will provide an accurate result for any given design, and any such test will only apply to the length of rope tested.
Refer to CalQlata's Technical Help for expected levels of accuracy for this calculator.
