15 SECTION 1 - Wire RopeRotation Resistant RopesIn certain instances the use of rotation-resistant wire rope is necessary to provide rotational stability to thelifted load. In general, the use of these wire ropes is limited to those situations where it is impractical to:1. Use a tag line2. Relocate rope dead end.3. <strong>Inc</strong>rease sheave sizes.4. Eliminate “odd-part” reeving.5. Significantly reduce rope loading and rope fall length.Rotation-resistant wire ropes have less of a tendency to unlay when loaded than do conventional wire ropes.This results in improved rotational stability to the lifted load. Rotation-resistant wire ropes are designed in sucha way that the rotational force of the outer strands is partially counteracted by the rotational force of the innerstrands or core when the rope is subjected to a load.The chart compares the rotational properties of rotation-resistant ropes with a standard 6x25 wire rope. Therotation-resistant ropes far surpass the rotational stability of a conventional 6x25 IWRC wire rope on both shortand long falls.SAFETY DESIGN FACTORSASME B30.5 specifies that rotation-resistant ropes have a safety design factor of five or greater. The required strengthdesign factor of rotation-resistant rope becomes very important from the standpoint of maintaining the inherent low rotationof the rope and eliminating any tendency to overload the inner core, thereby causing a reduction in rope strength.HANDLING & INSTALLATIONPrecautions should be followed when using rotation-resistant wire rope. The rope ends must be properly seized andsecured (refer to Handling and Installation: Seizing Wire Rope) and cut with a saw or impact hammer to prevent unlaying ofthe strands.Attachment of end fittings must be done with care to prevent kinking or unlaying of rope, which harms the rotationalbalance of the rope.Operation of rotation-resistant wire ropes (excluding SFP 35 ) with a swivel is generally not recommended. Theuse of a swivel allows the inner core to twist tighter, resulting in a significant reduction in rope strength, possibly leading topremature rope failure. A swivel may be used as a temporary device only during the initial installation period to help eliminateany installation-induced twisting or cabling.The swivel must be removed from the reeving after the rope installation is completed and before the crane beginsoperation.Due to the opposite lay direction of the inner core and outer strand layers in rotation-resistant ropes, care should betaken to avoid shock loading. Shock loading will result in distortion of the rope structure, causing birdcaging, core protrusion,etc. Due to the potential for complete rope failure, shockloaded wire ropes must be immediately removed from service.FOR MORE INFORMATION CONTACT OUR NEAREST BRANCH OFFICE
SECTION 1 - Wire Rope 16CAUTIONThe rated strengths of the 19 x7 class and 8 x19 class wire ropes are less than wire ropes in the 6x19 and 6x36 Classes.Larger sheaves are required in order to achieve comparable fatigue life. Refer to Technical Information: Effect of SheaveSize for further information on proper sheave sizes.19x7 Rotation-Resistant8x19 Rotation-ResistantStrands: 19Wires per strand:7Core: WSCStandard grade(s):EIPSLay: RegularFinish: BrightStrands: 8Wires per strand: 19Core: IWRCStandard grade(s):EIPSLay: RegularFinish: Bright19x7 is recommended for hoistingunguided loads with a single-part line.The rotation-resistant properties of thisrope are secured by two layers of strands. Theinner strands are left lay, while the 12 outerstrands are right lay, which enables one layer tocounteract the other layer’s rotation.The rotation-resistant characteristics ofthe 19x7 wire ropes are superior to those of the8x19 Class wire ropes.The 8x19 Classification rotation-resistantropes are recommended for hoisting unguidedloads with a single-part or multi-part line.The eight outer strands are manufactured inright lay, with the inner strands being left lay.These ropes are slightly stronger and significantlymore rugged than the 19x7 construction.However, the rotation-resistant properties of the8x19 rotation- resistant ropes are much less thanthose of the 19x7 construction.These ropes are manufactured in right regularlay in the 8x19 Seale and 8x25 Filler Wireconstructions.Rope Diameter Approx.
