Product Information
Characteristics
Inner strands are left lang lay; outer strands are right regular lay; the natural rotation tendency of one layer is balanced by the other. Not recommended for multiple part lifting.

*Acceptance strength is not less than 2 1/2% below the nominal breaking strengths listed.
Note: These strengths apply only when a test is conducted with both ends fixed.
When in use, the strength of these ropes may be reduced if one end is free to rotate.
Blue Strand Rotation Resistant Ropes are available in a full range of sizes, grades
and constructions:
• Standard constructions for single part and multipart lifting.
• Special wire rope constructions for increased service life in particularly demanding
applications – DYFORM-18, Dyform 34LR and 35LS.
NOTE:
1. Swivels are not recommended for use with rotation resistant ropes.
2. Although B30 standards permit rotation resistant ropes to be used under certain
conditions at design factors of 3.5:1.

NOT FOR AIRCRAFT USE. (“Aircraft Cable” has become an accepted industry term for small diameter 7×7 and 7×19 construction wire rope intended for industrial and marine application.) Read important warnings and information.
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. Wire rope must be properly stored, handled, 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. WARNING!
