With tuck splices in three-strand and eight-strand synthetic ropes, no less than four full tucks shall be used. Short splices shall contain at least six full tucks, three on each side of the center of the splice. Strand end tails in all tuck splices shall not be trimmed short (cut flush with the body of the rope). In cases where the projecting tails may be objectionable, the tails shall be tapered and buried into the body of the rope using two additional tucks. Synthetic rope slings shall have a minimum undisturbed length of rope of 10 times the rope diameter between the last tuck of tuck splices or between the ends of the buried tails or strands of other types of splices. The diameter and width of the bearing surface of the fitting can affect the strength of the sling. The sling manufacturer's recommendation should be followed when fittings are used with the sling. Knots, clips, or clamps shall not be used to fabricate slings. If thimbles do not have ears to prevent rotation, they should be lashed to the rope. Thimbles should be used in the sling whenever possible, installed in a manner that will prevent the thimble from rotating inside the eye or falling out of the eye. 9-4.7.4 Replacement of Sling Identification Replacement of the sling identification shall be considered a repair as specific in paras. 9-4.9.5(a) and (b). Additional proof testing is not required. SECTION 9-4.8: EFFECTS OF ENVIRONMENT 9-4.8.1 Temperature (a) (b) Polyester and nylon rope slings shall not be used in contact with objects or at temperatures in excess of 194°F (90°C) or at temperatures below -40°F (-40°C). Some synthetic yarns do not retain their published breaking strength during long-term exposure above 140°F (60°C). The rope sling manufacturer should be consulted for the effects of long-term heat exposure. 9-4.8.2 Chemically Active Environments The strength of synthetic rope slings can be degraded by chemically active environments. This includes exposure to chemicals in the form of solids, liquids, gases, vapors or fumes. The sling manufacturer or qualified person should be consulted before slings are used in chemically active environments. 9-4.8.3 Sunlight & Ultraviolet Light J Henry Holland Alabama Sling Center Tennessee Sling Center Phone: 757-460-3300 Phone: 205-744-0230 Phone: 901-345-8918 (Memphis) Phone: 205-345-4701 www.jhenryholland.com www.alabamaslingcenter.com Phone: 423-634-9005 (Chattanooga) www.kcicraneservice.com www.tennesseeslingcenter.com KCI Crane Service Overhead Cranes / Jibs Fall Protection Contractors Supply Load Securement The strength of synthetic rope slings is degraded by exposure to sunlight or ultraviolet light.

Matching the Rope to the Application All ropes have individual characteristics, reflecting the different properties of the various materials used in rope making. For example: Polyester (Dacron) has excellent resistance to abrasion, flexing, creep (tendency to elongate and break under continuous load), ultraviolet radiation, high temperature and most chemicals. It has low elongation and is unaffected by water. Nylon is about 17% lighter than polyester, rates about the same in abrasion, flexure, ultraviolet, and chemical resistance, but resistance to creep and elevated temperatures is somewhat lower, and it loses 10% to 15% of its breaking strength when wet. Higher elongation makes nylon excellent for dynamic loading, but due to its rapid recovery on release of load, there are hazards from recoil. Use eye splices at points of attachment. Avoid knots in rope. Avoid running rope over sharp corners or edges or around diameters less than eight times the diameter of the rope. Protect from damage such as cutting, wedging and severe abrasion. Store away from exposure to sun or rain, and avoid such exposure as much as possible. To dry wet rope, hang it loosely in coils. Keep rope away from chemicals harmful to your specific type of rope. (With nylon rope, avoid strong acids; polyester rope: strong alkalis; polypropylene rope: hot petroleum-based oils and solvents; manila rope: acids, alkalis, detergents, and most other chemical agents.) Before Loading Inspect the rope. Be sure the rope is in satisfactory condition and that you are using it in the recommended manner. Be sure that the load weight is accurately estimated, and that the rope selected is correct for that working load. You must determine if your application involves shock loading, long-term sustained loading or rated temperatures. If knots must be used for attachment or along the rope, or if the rope must be used around sharp bends or small radii, you must reduce by 40 percent the acceptable working load on the rope being used. Overhead Cranes / Jibs Hoists Services Contractors Supply Polypropylene is the lightest of rope materials. It floats and is unaffected by water. It resists most chemicals, and has fair resistance to abrasion and flexure. Degradation will result from continuous or excessive exposure to sunlight or ultraviolet radiation. Breaking strength decreases as temperature rises, and its resistance to creep is poor. Combination ropes—blends of polyester and polyolefins—provide surface characteristics of Engineered Products You can best utilize the strength of your rope and promote on-the-job safety by following these rules: Slings Cuts, gouges, badly abraded spots. Seriously worn surface yarns. Considerable filament or fiber breakage along the line where adjacent strands meet. (Light fuzzing is acceptable.) Particles of broken filaments or fibers inside the rope between the strands. (Check inside the rope.) Discoloration or harshness that may mean chemical damage or excessive exposure to sunlight. Check filaments or fibers for weakness or brittleness. Kinks or hockles. If any of the above signs of possible damage appear, the rope may be unsafe.

Recommended Procedure for Using Rope Hardware When inspecting rope, look for the following: Lifting Products The most common error in using rope is ignoring signs of excessive wear or damage incurred on the job. Any rope should be inspected frequently, especially if it is used in applications involving a risk of personal injury or property damage. Wire Rope polyester with the lightweight and economy of a polyolefin. Aramid (Kevlar) fiber is slightly heavier than polyester and has more than twice polyester’s tenacity. Creep resistance is excellent but resistance to abrasion and flexure are inferior. Low stretch prevents efficient utilization of its very high fiber strength except in small lines or special constructions. Cordage Inspection SEE PRODUCT GUIDELINES ON PAGES 794 - 795. Load Securement GUIDELINES Rope Technical Data 763 MazzellaCatalog13_Cordage.indd 763 7/3/13 10:20 AM GUIDELINES Efficiencies of Common Rope Splices, Knots, Bends & Hitches Besides being more closely related to actual field use, this splice is most convenient for test purposes since it offers the longest method of attachment. These pages have been compiled so that both our own personnel and those of our customers can better understand exactly what to expect from ropes which have been spliced, knotted or hitched. It should be noted that only Eye Splice, either with or without a thimble, should be seized with marline or wrapped with tape for longer wear. When using a thimble for an Eye Splice with synthetic fiber rope, it is advisable to use an eared thimble for greater security. All of the efficiencies listed herein either correspond with or take precedence over previously published figures. Short Splice—The Short Splice, which is used to join two ends, is essentially the same as the Eye Splice. If the splicer uses the same number of tucks back in each direction and tapers the splice in a manner similar to the Eye Splice, the efficiency, of the Short Splice will be very close to that of the Eye Splice (See Figure 1). The only disadvantage to the Short Splice is that it greatly increases the diameter of the rope at that point so that it may not pass through rings or over sheaves. Efficiency of Splices Before discussing individual splices, it should first be understood that we have traditionally based our published rope strengths on tests using an eye splice at both ends. When tested, the ropes invariably part at the splice. This may seem conservative, on our part, since a straight, unspliced line will have greater strength. However, it is hard to conceive an actual “in use” application where sufficient force can be applied to reach the breaking point without some sort of splice, knot or hitch being utilized. Occasionally, where small ropes may be tested by securing both ends with several turns around a post or cleat, break strengths at slightly higher than eye-spliced results may sometimes be achieved. Long Splice—You will note in Figure 1 that Long Splices do not afford the strength of the Short Splice. However, the Long Splice causes a smaller increase in diameter. Properly tucked and well pounded down, the Long Splice will often run satisfactorily over sheaves. If ordered from our mills, care must be taken in terminology to avoid confusion with the Long Blind Splice, listed below. In the Long Splice, strands are not divided, but are tucked back over and under in both directions. As you will see, in certain cases, obtainable splice efficiencies may sometimes suggest the desirability of using a slightly smaller diameter continuous length of line for a larger diameter, which must be long or short spliced. Long Blind Splice—Sometimes called the “Transmission Splice”, the Long Blind Splice sacrifices a great deal of strength in order to preserve a constant bulge-free diameter. Instructions for making the various splices are shown in specific brochures and booklets, which deal with the proper use of rope. The mating strands are divided in half and recombined. This introduces points of seriously reduced strength. The Long Blind Splice should never be used except where the reduced strength is acceptable.

Therefore we can, for comparison purposes, consider this splice to be 100% efficient. Long Splice The test data were compiled using rope constructed of Nylon, Dacron, Polypropylene, Manila and P/D combinations. Percentage of efficiency varies little for ropes of dissimilar Figure 1 compositions used in the same type of splice.

It is recommended that the end user establish working loads and safety factors based on best practices established by the end user's industry; by professional judgment and personal experience; and after thorough assessment of all risks. The SWL is a guideline for the use of a rope in good condition for non-critical applications and should be reduced where life, limb, or valuable property is involved, or in cases of exceptional service such as shock loading, sustained loading, severe vibration, etc. The Cordage Institute specifies that the SWL of a rope shall be determined by dividing the Minimum Tensile Strength of the rope by a safety factor. The safety factor ranges from 5 to 12 for non-critical uses and is typically set at 15 for life lines. Heat: Polyester melts at 480°F with progressive strength loss above 300°F. Dielectrics: Good resistance to the passage of electrical current. However, dirt, surface contaminants, water entrapment, and the like can significantly affect dielectric properties. Extreme caution should be exercised any time a rope is in the proximity of live circuits. Sheaves: Recommended sheave diameter to rope diameter is 8:1.

To avoid diving, CROSS WINDING: SECOND CROSS cross winding is recommended. When cross winding, start with two layers of level wound rope using the appropriate back tension. At the end of the second layer, pull the rope quickly across the drum, allow it to wind one full CROSS WINDING: LEVEL LAYER turn at the side of the drum, then quickly pull it back to the opposite side of the drum. This will force the rope to cross in the middle, and form a barrier that will prevent the rope from diving into the lower layers of the drum when placed under load.

Break strength should not be mistaken for safe working load. Safe Working Load: Because of the wide range of rope use, rope condition and the degree of risk of life or property, it is not possible to make a blanket recommendation for safe working load. It is ultimately dependent on the rope user to determine what percentage of break strength is their own safe working load. Wear: Ropes wear out with use; the more severe the usage, the greater the wear. It is often not possible to detect wear on a rope by visible signs alone. Therefore, it is recommended that the rope user determine a retirement criteria for ropes in their application. For assistance in developing safe working load and retirement criteria for each application please call or write Phillystran.

For complete warning and application information, see Phillystran, Inc. at www.phillystran.com 794 MazzellaCatalog13_Cordage.indd 794 7/3/13 10:20 AM Cordage Institute International Warnings & Guidelines - Loads are not accurately known - High or continuous dynamic loads are anticipated (See Section 6) - Shock loads are anticipated - Extensive cyclic loads are likely to occur - Tension is on the rope for long periods - Knots are used, as knots can reduce strength by as much as 50% - Operators are not well trained - Operation/use procedures are not well defined and/or controlled. - Severe abrasion is likely to occur from exposure to rough surfaces or cutting edges, or by contamination from dirt and grit. WARNING The use of rope and cordage products has inherent safety risks which are subject to highly variable conditions and which may change over time. Compliance with standards and guidelines of the Cordage Institute does not guarantee safe use under all circumstances, and the Institute disclaims any responsibility for accidents which may occur. If the user has any questions or uncertainties about the proper use of rope or cordage or about safe practices, consult a professional engineer or qualified individual. Expert Guidance is Strongly Suggested for the Following Situations: ■ Rope is used constantly over pulleys or around a small bend. ■ Rope is used at elevated temperature that may glaze, weaken or melt the fibers. ■ Rope is used in the presence of hazardous chemicals. ■ Rope is not new and is of unknown properties and/or prior use. ■ Rope is not inspected frequently or adequately. Rope will be in service for long periods that may lose strength ■ due to fatigue. CI Guideline 2003 Fibers for Cable, Cordage, Rope and Twine explains some of the effects of elevated temperature and chemicals on synthetic fibers. 5. Calculation of Values ■ After the WL has been estimated and the DF for an application has been determined, a rope can be selected by calculating the necessary new rope Minimum Breaking Strength. The required MBS is determined by multiplying the Working Load by Design Factor. WL x DF = MBS. For example, an application with a Working Load of 3 tons and a Design Factor of 10 would require an rope with MBS = 3 x 10 = 30 tons. ■ Similarly, the Working Load Limit of a new rope is determined by dividing the Minimum Breaking Strength by the Design Factor for a given application. MBS ÷ DF = WLL. Examples of WLL, based on a DF of 5:1 and 12:1, are given in individual Cordage Institute Standards. The WLL in CI standards are for new ropes with standard terminations. 6. Dynamic Loading ■ Nearly all rope in use is subject to Dynamic Loading to some degree. Whenever a load is picked up, stopped, moved or swung there is an increased force due to the acceleration or dynamics of the movement. The more rapidly or suddenly such actions occur, the greater the forces. In extreme cases, the force sustained by the rope may be two, three, or even more times the static load. (e.g., when picking up a tow on a slack line or using a rope to stop a falling object) Therefore, in applications such as towing lines, lifelines, safety lines, climbing ropes, etc., the DF must reflect the added risk involved. If significant dynamic load is foreseen, a DF at or above the high end of the range should be considered. Loads should be handled slowly and smoothly to minimize dynamic effects. ■ Users should also be aware that dynamic effects are greater on a low elongation rope, such as manila, than a high-elongation rope, such as nylon. Also note that dynamic effects are more significant on short segments of rope as opposed to longer ones. ■ Excessive dynamic loading will shorten the life of a line and/or cause premature failure. 7. Recoil / Snapback Safety Warning ■ When a tensioned rope breaks, an attachment fails, or either are suddenly released, the energy in the rope will cause it or the attachment to recoil back in unpredictable directions with great force, resulting in possible injury or death to persons in its path. Persons should never stand in line with or in the general path of rope under tension to avoid snapback injuries. 8. Special Applications ■ The DF ranges can be lower or higher than recommended in applications where actual field experience has proven successful, where a recognized standard or specification exists, where qualified professionals have made a thorough engineering analysis of all conditions of use and/or a regulatory agency has granted specific permission. In such controlled cases, breaking strength, elongation, energy absorption, and other factors, including operating procedures, must be evaluated during the selection of the Design Factor. ■ In addition to the above, more specific guidelines should be considered for applications such as life safety and marine use. CI 1401-06 Safer Use of Fiber Rope Purpose ■ This Guideline is provided to help in the selection and safer use of cordage products. Compliance with Cordage Institute Standards and Guidelines does not guarantee safe use under all circumstances, and the Institute disclaims any responsibility for any accidents that may occur. 1. Overview ■ There are inherent risks in the use of rope and cordage because such products are subject to highly variable conditions that change over time. Therefore, Design Factor selections and Working Load Limits must be calculated with consideration of exposure to risk and actual conditions of use for each application. If in doubt, consult an experienced engineer or other qualified individual regarding the design, application and selection of a rope product. 2. Minimum Breaking Strength ■ The Minimum Breaking Strength (MBS) is the force that a given rope is required to meet or exceed in a laboratory test when it is new and unused. MBS values are given in Cordage Institute Standards and individual manufacturers’ specifications. 3. Working Load / Working Load Limit ■ The Working Load (WL) is the weight or force applied to rope or cordage in a given application. ■ The Working Load Limit (WLL) is a guideline for the maximum allowable capacity of a rope product and should not be exceeded. ■ Applied loads higher than a specified WLL can overstress and damage fibers, resulting in premature rope failure. The Working Load of an application should not exceed the WLL of the rope for optimal product performance and the safety of personnel and property. 4. Design Factors ■ The Design Factor (DF) is the ratio between the MBS and WL. This value is the margin of safety for an application. For a particular application, the factors affecting rope behavior and the degrees of risk to life, personnel and property must be considered when setting a DF. ■ Commercial and industrial users must determine a DF based on actual service conditions and establish operating procedures for a specific application. A “general use” consumer must also assess his application and determine conditions of use and hazards that may apply. ■ As a rule, the more severe the application, the higher the DF needs to be. Selection of a DF in the general range between 5:1 and 12:1 is recommended. A design factor at the low end of this range should only be selected with expert knowledge of conditions and professional estimate of risk. DF at or above the high end of the range should be used for more severe conditions of use. When in doubt, always select the highest practical DF, or contact the manufacturer for additional guidance. Engineering assistance may be necessary to determine the service loads and risks and to set the appropriate DF. Considerations in the Selection of a Design Factor ■ Experience is the best guide for determining a DF. Select a DF value used in a similar application that proved successful. ■ Consider increasing the Design Factor if: - Problems have previously been observed in similar applications - Injury, death or loss of property may result if rope fails For complete safety and usage information, see Cordage Institute International at www.ropecord.com 795 MazzellaCatalog13_Cordage.indd 795 7/3/13 10:20 AM
