Special Rope Constructions

Unusual operating conditions often require ropes of special design to better withstand stresses or environments that would seriously impair performance of more conventional designs.  Ropes that may meet these needs include the following:

Flex-X®. A special process that creates more strand surface area on each strand to help spread contact, decrease wear, reduce corrugation and extend service life.  With greater surface area and more steel per diameter than conventional ropes, Flex-X provides higher strength and better wear resistance.  Its high-density strands are compacted for extra strength and resistance to abrasion, crushing, and bending fatigue.

 

TUF-KOTE®/PFV®.  A plastic impregnated wire rope proven to provide longer service life and a cleaner operation.  On the inside, top-of-the-line wire rope effectively withstands the demanding pressures of your job.  The polymer is applied at high pressure to force the material into the rope, serving to cushion the strands, distribute internal stresses, keep in wire rope lubricant and keep out dirt and debris.  On the outside, the engineered polymer plastic is designed to provide a cleaner operation and reduces wear on sheaves and drums.

 

7-Flex®.  A rope construction that offers improved resistance to bending fatigue compared to a 6 strand rope of the same diameter due to a combination of the outer wire size and the seventh strand.  The use of a 26 Warrington Seale (WS) strand construction provides a good balance of operating characteristics.

 

Swaged ropes.  These ropes offer higher strength than standard ropes of the same diameter while providing greater resistance to drum crushing, scrubbing, and similar surface wear.  During manufacture, the rope is swaged to produce a compact cross-section with minimum voids and greater surface area.
