<strong>Wire</strong> <strong>Rope</strong><br />
<strong>Python</strong> ® Compac 18 Rotation Resistant <strong>Wire</strong> <strong>Rope</strong><br />
2-layer type, refer<br />
to page 10<br />
Compac 18 (18x19)<br />
12 outer rope strands<br />
19 wire SEALE strand construction for better flexibility<br />
Complete rope is compacted for increased abrasion resistance and better spooling<br />
Inner strands are reversed lay to provide rotation resistance feature<br />
Main Applications:<br />
<strong>Python</strong> ® Compac 18 is recommended for both multipart load and<br />
single part applications where a medium rotational stability is<br />
needed. Use as main- and auxiliary hoist line on GROVE, LINK<br />
BELT, MANITOWOC, TEREX and other US made mobile- and truck<br />
cranes. Often used as a single point line. Large lifting heights will<br />
require a tag line to prevent spinning of the load.<br />
Also used very successfully as a pulling rope on underground cable<br />
pulling winches.<br />
NOT recommended for construction tower cranes.<br />
<strong>Rope</strong> Characteristic:<br />
Using the rope to it’s maximum fatigue life will cause the rope to<br />
deteriorate from the inside out. For this reason we do not<br />
recommend this rope to be used on construction for tower cranes.<br />
However, mobile and truck mounted cranes are operated on a<br />
much less severe duty cycle and it is not expected that <strong>Python</strong> ®<br />
Compac18 has to be replaced because of inner rope fatigue but<br />
because of other mechanical damages. Keep in mind that this<br />
statement covers normal mobile crane use only.<br />
Compacted strands provide improved abrasion resistance as<br />
compared with round wire types because of the greater wire and<br />
strand bearing surfaces contacting sheaves and drums.<br />
<strong>Python</strong> ® Compac 18 wire ropes are more resistant to the effects of<br />
drum crushing than 19x7 due to the compacted strands and<br />
smoothness of the rope surface.<br />
With 18 strands of 19 wires in all sizes, <strong>Python</strong> ® Compac 18<br />
remains extremely flexible and easy to handle.<br />
<strong>Python</strong> ® Compac 18 ropes are ROTATION<br />
RESISTANT but NOT non-rotating.<br />
Do NOT use <strong>Python</strong>®<br />
Compac 18 wire rope<br />
attached to a swivel or<br />
have one or both rope<br />
ends rotate freely under<br />
load. Doing so will result<br />
in a loss of rope strength<br />
of between 30% to 40%.<br />
Block Twisting (Cabling)<br />
will occur when used<br />
exceeding certain lifting<br />
heights. This is NOT a<br />
non-rotating rope.<br />
