In a core-dependent Twin rope construction, the interior core bears the entire load. The role of the cover is to protect the core from abrasion and other potential damage.
Construction of load-sharing Twin
In a double braid rope, the core and cover share the load equally, even though applications may vary considerably.
Construction of One
With a round braid the alone-standing loadbearing braid determines the technical properties: it functions without a core – or without a cover, depending on your viewof things…
Construction of Square
In a square plait rope, eight strands are interwoven to form a roughly square-shaped cross-section. It is very robust and has good grip, while simultaneously being relatively economic and easy to splice.
