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. |
