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:

 

 

 

 

» Special Rope Styles

 

Flex-X. A special process that creates more strand surface area on the rope 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®/PF V®. 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.

8 strand wire ropes. In general, 8 strand ropes are designed for specialized applications that can take advantage of their special traits. An 8 strand rope will have smaller strands and a larger core than a 6 strand rope of the same diameter. So, it can be expected to display greater bendability, but lower minimum breaking force due to the reduction in metallic area of strand cross-sections. A standard 8 strand rope will be less stable, as a general rule, than a 6 strand rope and will be more subject to crushing, especially when it has a fiber core.

 

 

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.

 

FLEX-K0TE®/PFV®. Our highest-performance rope that combines the unique qualities of Flex-X compacted wire rope with the toughness of TUF-KOTE/PFV. FLEX-KOTE/ PFV enhances the advantages of a compact, higher-strength wire rope by impregnating to the core with polymer plastic to increase fatigue, crushing and abrasion resistance.

 

Flattened (triangular) strand. These ropes feature
"shaped strands formed so they will close together to achieve greater metallic area in the rope's cross-section and greater bearing surface for contact with sheaves and drums.

 

 

 

 

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.
