know more about a Rope

Working Loads -It is impossible to establish hard and fast recommendations regarding working loads due to the wide range of rope use, rope conditions, exposure to several factors affecting rope behavior, and the degree of risk to life and property involved. The tabulations for working loads are based on new, unused rope in excellent condition. These are only guidelines, even when having appropriate splices, and being used in non-critical applications and under normal conditions. If possible injury to people or damage to property exist, working loads should be reduced.
Never increase the working load beyond given guidelines without expert advice as to the conditions and risk involved. It must be determined that the rope is in excellent condition. Figures given as working loads are void if the rope has been subjected to dynamic loading, high temperatures, long periods of load, extreme stress, improper storage or improper use.

DYNAMIC LOADING - occurs when rope is subjected to sudden or extreme stress such as abrupt starting or stopping of a load. The effect of dynamic loading is greater on low-elongation rope, such as polypropylene than on high-elongation rope, such as nylon. Also the effect is greater on a short rope than on a long rope.

TENSILE STRENGTHS - are determined from tests on new, unused rope in accordance with standard test methods of the Cordage Institute, 994 Old Eagle Schoolhouse Rd., Suite 1019, Wayne, Pennsylvania 19087.

Rope Construction:
HOLLOW BRAIDS - Fully spliceable, and resistant to moisture and rot. It floats indefinitely and cannot hockle, kink or backlay. A few of the many uses for hollow braid rope include water ski tows, anchor lines, pool rope, dog leashes and applications where quick easy splicing to hardware or other components is desirable

SOLID BRAIDS - Abrasion resistance, high strength, low stretch and ease of handling are qualities which make solid braids ideal for clotheslines, pulleys, tie downs, flag poles, awnings and applications where strength resistance to wear are important.

TWISTED ROPE - Size for size and pound for pound, is the strongest and least expensive rope manufactured today. It is a spliceable, general purpose rope used widely for anchor lines, dock lines, blocks and tackle, winch ropes, tow ropes, tie downs plus many industrial and marine uses.
When turned the opposite direction of the rope lay, twisted rope will hockle. Hockles are detrimental to rope wear and cause permanent damage when strain is applied.

MaterialNatural Fiber Ropes- Although less affected by sunlight than synthetic fibers, its very important to recognize the characteristics & limitations of natural (Abaca) fiber ropes such as manila. Even under ideal storage conditions, natural fibers will decompose & lose up to 50% of their tensile strength. Because theyre prone to mildew & dry rot, natural fiber ropes must be stored completely dry.

Synthetic Ropes -Man made fiber ropes are stronger and more durable than natural fiber ropes. They are generally not affected by rot, mildew or most chemicals and may be stored wet or dry. The service life of synthetic exceeds that of natural fiber ropes and have proven to be more efficient and cost effective.
NYLON - The strongest rope we supply. Nylons elasticity can absorb shock loads that would break ropes of other fibers. Resistant to abrasion, rot, petroleum products, marine growth and most chemicals, nylon rope will last many times longer than natural fiber ropes. When wet, nylon rope has approximately 15% less strength and this should be considered when selecting nylon rope.
POLYESTER - has less stretch and elasticity than nylon plus greater resistance to ultraviolet degradation from sunlight. Other characteristics of the two fibers are practically the same.
POLYPROPYLENE - Extensively used for many applications, polypropylene is a strong, lightweight, floating rope. Resistant to rot, mildew, petroleum products and most chemicals, polypropylene is an excellent all purpose utility rope.


Rope Use and Care:
OVERLOADING -
Avoid sudden strain. When a working load has been used to select a rope, the load must be handled slowly and smoothly to minimize dynamic effects and avoid exceeding the provision for them.

ABRASION - All rope will be severely damaged if subjected to rough surfaces or sharp edges. Chocks, winches, drums and other surfaces must be kept in good condition and free of
