Wire Rope Python ® Compac 18 Rotation Resistant Wire Rope 2-layer type, refer to page 10 Compac 18 (18x19) 12 outer rope strands 19 wire SEALE strand construction for better flexibility Complete rope is compacted for increased abrasion resistance and better spooling Inner strands are reversed lay to provide rotation resistance feature Main Applications: Python ® Compac 18 is recommended for both multipart load and single part applications where a medium rotational stability is needed. Use as main- and auxiliary hoist line on GROVE, LINK BELT, MANITOWOC, TEREX and other US made mobile- and truck cranes. Often used as a single point line. Large lifting heights will require a tag line to prevent spinning of the load. Also used very successfully as a pulling rope on underground cable pulling winches. NOT recommended for construction tower cranes. Rope Characteristic: Using the rope to it’s maximum fatigue life will cause the rope to deteriorate from the inside out. For this reason we do not recommend this rope to be used on construction for tower cranes. However, mobile and truck mounted cranes are operated on a much less severe duty cycle and it is not expected that Python ® Compac18 has to be replaced because of inner rope fatigue but because of other mechanical damages. Keep in mind that this statement covers normal mobile crane use only. Compacted strands provide improved abrasion resistance as compared with round wire types because of the greater wire and strand bearing surfaces contacting sheaves and drums. Python ® Compac 18 wire ropes are more resistant to the effects of drum crushing than 19x7 due to the compacted strands and smoothness of the rope surface. With 18 strands of 19 wires in all sizes, Python ® Compac 18 remains extremely flexible and easy to handle. Python ® Compac 18 ropes are ROTATION RESISTANT but NOT non-rotating. Do NOT use Python® Compac 18 wire rope attached to a swivel or have one or both rope ends rotate freely under load. Doing so will result in a loss of rope strength of between 30% to 40%. Block Twisting (Cabling) will occur when used exceeding certain lifting heights. This is NOT a non-rotating rope. Call for advice -26-
Wire Rope Breaking Strengths Note: The maximum CAPACITY, WORKING LOAD LIMIT (WLL), or LINE PULL of the rope usually is 1/5 of the below stated values. For specific information consult the standards applicable to your rope application.

Use as main- and auxiliary hoist line on GROVE, LINK BELT, MANITOWOC, TEREX and other US made smaller mobile- and truck cranes. Often used as a single point line. Larger lifting heights will require a tag line to prevent spinning of the load and/or block twisting. NOT recommended for construction tower cranes.
