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. Following are some of our special constructions that have been developed through WireCo WorldGroup's exclusive PowerSteel Technology.

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. |

TUF-MAX
These shovel ropes are manufactured
with an enhanced coating process that
makes them more resistant to external
rope wear and helps extend drum and
sheave life. |
|
|
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. |

8 strand
wire ropes. In general,
8 strand wire 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. |

|
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.

Flex-X 7® CC (LoadStar).
Flex-X 7® CC (LoadStar) extended duty crane and hoist ropes were developed primarily for the container crane industry where repetitive, continuous operations are a fact of life. Subsequent research and extensive testing have shown that Flex-X 7® CC (LoadStar) delivers the same exceptional fatigue resistance and service life to other applications where bending fatigue is a problem.
