Flex-X® 6 wire ropes
Flex-X 6 Flyer (732kb - right click to save)
Most applications for wire rope are extremely demanding.
Wire rope must resist crushing, bending fatigue and
abrasion. For example, clamshell closing lines must
resist bending fatigue and boom hoists are subject
to pressures that cause crushing. Overhead hoists
test the stability and strength of a wire rope. All
drum-related applications demand a rope that will
spool and operate smoothly and dependably.
Flex-X 6 users receive superior performance and increased
service life in many applications compared to the
ropes they had previously employed. When compared
to conventional 6 strand ropes, Flex-X 6 ropes provide
greater surface area and more steel per given diameter,
which increases rope stability and strength, too.
This results in longer service life and less sheave
and drum wear.

Flex-X® 9 wire ropes
Flex-X 9 Flyer (595kb - right click to save)
Wire Rope Corporation of America, Incorporated
announces the newest addition to the Flex-X
family, Flex-X 9.
Our research and field engineers have devoted
a great deal of time and effort to design Flex-X
9, the very latest in compacted wire rope. Its
high-density strands deliver extra strength,
surprising bendability, a stubborn resistance
to abrasion, and perhaps its greatest asset
to users, a high resistance to drum crushing.
Beyond the design, Flex-X 9 is manufactured
with a dual compaction process to produce a
compact cross-section with minimum voids and
greater surface area on outer wires that contact
drums, sheaves and the rope, itself, during
operation. This process also results in high-density,
compacted strands to minimize nicking at strand-to-strand
contact points. |
Flex-X 9 features
compacted strands and swaging for
an extra measure
of drum crushing resistance and increased stability. |

Now you can keep your crane up and running longer.
Flex-X 9 has been designed to resist crushing. However,
when rope deterioration inevitably occurs, Flex-X
9’s unique design greatly assists the operator
with crucial rope inspections. Wire breaks with Flex-X
9 are typically found on the outside of the rope,
making them much easier to identify. Any rope inspector
can appreciate that.
TUF-KOTE® / PFV wire ropes
TUF-KOTE / PFV, the plastic-impregnated wire rope,
has proven in many applications to give you longer
service life and cleaner operation than conventional
wire ropes.
On the inside, you'll find our top-of-the-line wire
rope that effectively withstands the tough pressures
of your demanding jobs. On the outside, you'll see
a specially engineered polymer plastic designed to
overcome even harsher conditions. This polymer is
applied at high pressure to force the material into
the rope, filling the valleys of the strands. TUF-KOTE
/ PFV cushions the strands, distributes internal stresses,
keeps in wire rope lubricant and keeps out dirt and
debris.
TUF-KOTE / PFV doesn't melt or soften from the heat
of your normal operating temperatures. It's also virtually
unaffected by sunlight and cold weather. The result
is longer service life from your wire rope.
TUF-KOTE / PFV also helps shed water and dirt, giving you
a clean, smooth surface to make it easy to pass over sheaves
and onto drums. This smooth surface works to clean and polish
as it extends the service life of your sheaves and drums.
That reduces your cleanup requirements and your maintenance
costs.
A unique plastic impregnated
wire rope designed specifically for severe corrosive conditions.
Space Lay Ropes

Ordinary plastic-coated wire rope vs.
SPACE-LAY
With ordinary plastic-coated wire rope, the individual metal
strands are in direct contact with each other at many points.
As a result, the metal-to-metal contact causes internal friction
and wear. Even more important, with conventional constructions,
there is no interlocking bond. If the outer cover (blue) becomes
cut or abraded, it is easily peeled off, exposing the bare
metal strands to corrosion.
In SPACE-LAY construction, each individual strand is separated
from all the others by one or more extra-large “spacer-wires.”
This design serves two important functions: (1) It enables
the extruded plastic (yellow) to form a wall of protection
around EACH strand. (2) It also assures a tight, interlocking
bond between the inner plastic filler and the outer plastic
jacket.
No peeling or leaking. PLUS, in
SPACE-LAY construction, each individual wire is galvanized
for additional corrosion protection.
For many applications, the SPACE-LAY design
has proven far superior to all other known types of plastic
coated wire rope. It has also outlasted bright, galvanized
and stainless steel ropes – especially where submersion
or abrasion prevents formation of a protective oxide film,
which these metals require to resist corrosive elements. Under
such conditions, SPACE-LAY plastic-impregnated and coated
galvanized wire rope offers important advantages to users.

Flattened Strand Ropes
Also called triangular strand, flattened strand ropes perform
exceptionally well on certain installations, especially those
involving heavy loads where the speed of operation is slow,
where adequate diameter sheaves and drums are used, or where
a crush resistant rope is required. Typical installations
include skip hoists, large overhead cranes, boom hoist ropes
and mine shaft hoists.
Their distinguishing physical feature is their relatively
flat exposed surfaces of strands. As a result, the rope
exterior is more nearly a smooth, continuous circle than
that of regular round strand wire rope. Flattened strand
ropes are made with two layers of 12 wires around a triangular-shaped
center. We offer a 6x30 Style G using a six-wire center
as the standard construction.
The advantages of flattened strand ropes
The flattened shape forms a bearing surface
with more contact points on each strand than a round strand
rope. With more sheave contact, weight and wear on the rope
are distributed more uniformly than on a typical round strand
rope. The triangular strand structure also results in more
steel in the cross-section than a standard round strand
rope of equal size.
