About Non Rotating Wire Rope
Non Rotating/Rotation-resistant wire ropes are specially designed to re-sist spin or rotation while under load.
Due to their design, they have certain restrictions on their application and special handling requirements that are unnecessary with other constructions.
The rotation-resistant characteristics are attained by a design of two or more layers of strands having differing (right and left) directions of lay, as shown below.
Under load, one layer’s directional rotation is counteracted by the tendency of the other layer(s) to rotate in the opposite direction. To impart greater resistance to rotation, these ropes are
designed with a greater number of smaller diameter strands (when compared with the design of 6- strand constructions).
The combination of smaller diameter strands and differing rope lays makes for a very delicate balance which can easily be “unbalanced” at anytime.

Features
17x7 Non Rotating Wire Rope
Ropes of those constructions are offered in the range of diameters 6 - 60 mm; these are the ropes with reduced spinning, which are intended mainly for building and industrial cranes (cranes, travelling cranes, industrial overhead cranes) with medium lifting height, working with sheaves, with multi-rope sheave block rigging.
NOTE: the ropes described above should not work with rotating clamping (swivel shackle)!!! It is allowable to operate the rope with rotating clamping in the first lifting cycle only, in order to compensate stresses, which arose due to installation. After the first lifting, the rope end should be blocked permanently.
Applications
Equipment for port load and unload derrick tower crane.
