Non Rotating galvanised steel wire rope 4 Strands 4V x 39S 5fc
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
4 Strands wire rope was developed for ship cranes using bulk grabs to unload coal, iron ore, and other abrasive bulk loads. Moreover, it has shown it's superior feature of crush resistance when used with many other tough loads like timber logs which tends to easily crush normal wire rope.
Because of it's crush resistance it is also used on pile drivers and other heavy duty construction equipment which requires a crush resistant rope for multiple layer windings, even on smooth drums
Applications
Equipment for port load and unload derrick tower crane.
