Rotation Resistant Wire Ropes
19 X 19 ROTATION-RESISTANT
19 x 19 is recommended for both multipart load and singlepart fast line applications where rotational stability of the lifted
load is needed, such as for use as a long fall on offshore pedestal cranes, rough and all terrain cranes, and crawler cranes.
19 X 19 PROVIDES:
1 9 X 1 9 R O TAT I O N - R E S I S TA N T
Fatigue Resistance
Improved fatigue properties are derived through the
combination of the flexible 19 x 19 construction and die
drawn strands. The drawn strand surfaces minimize the
interstrand and interlayer nicking that take place in round
rotation-resistant ropes.
Resistance to Drum Crushing
19 x 19 wire ropes are resistant to the effects of drum
crushing due to the compacted strands and smoothness
of the rope surface.
Flexibility
With 19 strands of 19 wires in all diameters, 19 x 19
remains extremely flexible and easy to handle during both
the installation process and under the extremely harsh
conditions form fast line speeds during spooling.
WIRE ROPE
Abrasion Resistance
Die drawn ropes provide improved abrasion resistance as
compared with round wire ropes because of the greater
wire and strand bearing surfaces contacting sheaves and
drums.

WARNING: Any warranties, expressed or implied, concerning the use of this product apply only to the nominal strength of
new, unused wire rope. All equipment using this product must be properly used and maintained. Most importantly, wire
rope must be regularly inspected during use. Damage, abuse or improper maintenance can cause rope failure. Consult the
AISI Wire Rope Users Manual, ASME or ANSI Standards, before usage. Wire rope removal criteria are based on the use of
steel sheaves. If synthetic sheaves are used, consult the sheave equipment manufacturer.

Rotation Resistant Wire Ropes
35 X 7 ROTATION-RESISTANT
35 x 7 offers the best operating and performance characteristics of all rotation-resistant ropes. 35 x 7 is recommended for
crawler and truck-type crane load lines, tower crane hoist ropes, and other applications where high strength, low rotation
and/or the ability to withstand long falls is needed.

High Strength
35 x 7’s design and manufacturing process provides a
high strength rope which exceeds EEIP nominal breaking
strength.
35 X 7 ROTATION–RESISTANT
Superior Rotation Resistance
35 x 7 is the most rotation-resistant rope of all rotationresistant ropes. 35 x 7’s special design and multiplestrand construction provides superior rotation resistance.
Due to its rotation-resistant properties, 35 x 7 may be
used with a swivel in both singlepart and multipart
reeving.
Flexibility
35 x 7’s multiple strand design provides increased
flexibility, making it easy to install, and 35 x 7 offers
improved service life and better spooling at high line
speeds.
