SEMI ROTATION RESISTANT WIRE ROPE
Designed to generate only small levels of
torque and rotation when loaded. Designed without any rope core. The outer strands have an extremely long
lay length and therefore almost no tendency
to start to rotate under load.
According to VDI 2358, a wire rope is semi
rotation-resistant when: "the wire rope which turns
around its longitudinal axis when subjected to
unguided load and/or hardly transmits a torque to
the attachment at the end in the event of guided
" According to ISO 21669 and DIN EN 12385-3: "a rope is considered to be semi rotation resistant if it rotates at least once and at most four times around its axis at a length of 1000 x d under a load of 20 % of the minimum breaking force. In terms of rotation angle, the defined limits are between 360° and 1440°.
