	Wire rope - Wikipedia, the free encyclopedia
		Modern wire rope was invented by the German mining engineer Wilhelm Albert in the years between 1831 and 1834 for use in mining in the Harz Mountains in Clausthal, Lower Saxony, Germany.
		In America wire rope was later manufactured by John Roebling, forming the basis for his success in suspension bridge building.
		This flexibility is particularly vital in ropes used in machinery such as cranes or elevators as well as ropes used in transportation modes such as cable cars, cable railways, funiculars and aerial lifts.

	An Introduction to Wire Rope
		Wire rope is composed of wires, strands and a core.
		Ropes in this class are furnished in regular and lang lay with fiber core or independent wire rope core, preformed or not preformed.
		The wires under the outside layer of the Filler Wire rope are made up of a combination of main wires, each of the same size, and smaller filler wires, each of the same size, nested between the main wires.

	NASD: Wire Rope
		A wire rope thimble should be used in the loop eye at the end of the rope that is attached to the unloader.
		U-bolt wire rope clips must be attached with the base of the clip bearing against the live end of the rope, while the ‘U’ of the bolt presses against the dead end.
		Wire rope used to hoist silo unloaders is subject to neglect because it is normally used only once a year.

		Wire rope is a machine with dozens–even hundreds– of individual wires which are formed and fabricated to move or operate at close tolerances to one another.
		When a wire rope bends, each of its many wires slides and adjusts to accommodate the differences in length between the inside and outside of the bend.
		Wire ropes are identified by classifications based upon the number of strands and nominal number of wires in each strand.

	Wire Rope
		This method is not only useful for measuring the diameter of the rope, but also for determining the amount of wear and compression that has occurred while the rope has been in use.
		Wire rope is normally made slightly larger than its catalog (or nominal) size.
		This is a wire rope with a high strand -- a condition in which one or strands are worn before adjoining strands.

		Wire rope that is not destroyed might be used again by someone not aware of the hazard associated with that use.
		Wire rope should be properly seized on both sides of the cut with wire or strand.
		Seizing wire diameter and the number and length of the seizings will depend on the diameter of the wire rope, and whether or not it is preformed.

		A wire rope lay is a distance measured along the length of a rope within which the spiral strands complete one turn about the axis.
		If the distribution of broken wires is unequal and broken wire predominates in one or two strands, remove ropes when the number of broken wires per rope lay in the worst section of rope exceeds the values shown in Column B of the table.
		If four or five wires, side by side, are broken across the crown of the strands, remove ropes when the number of broken wires per rope lay in the worst section of rope exceeds values shown in column C of the table.

	Wire Ropes on Bilco Wire Rope & Supply Corp.
		This classification of wire rope covers ropes containing six strands with the number of wires per strand varying from a minimum of 27 to a maximum of 49.
		This classification is normally found in ropes of larger diameters or in situations where small sheave or drum diameters exist.
		Wire ropes of this class are more flexible than 6x19 class ropes due to the greater numbers of wires per strand, however the resistance to abrasion is less than 6x19 class ropes.

	VER SALES, INC. - Wire Rope
		DIAMETER IN In a multi-part wire rope system where the blocks have a tendency to twist, or for a single part hoist line which does not require the degree of rotation resistant properties found in a 19 x 7 rope, the 8 x 25 Resistwist rope has found successful application.
		Tests on rotation resistant ropes show that the length of service life between that point in time where the visible broken wire criteria for removal from service are met, and where actual rope failure occurs, is substantially shorter for rotation resistant ropes than for standard construction ropes.
		This practice, or any other which allows the rope to rotate while in service, can lead to unbalanced loading between inner and outer layers of strands, which may result in a short length of an operating rope, or there is unevenness of outer strands, the rope should be replaced.

		While the 6 x 19 ropes give primary emphasis to abrasion resistance in varying degrees, the 6 x 36 ropes are important for their fatigue resistance.
		As the rope size increases, for instance, a large number of wires can be used to achieve required fatigue resistance, and still those wires will be large enough to offer adequate resistance to abrasion.

		A typical wire rope may contain hundreds of individual wires which are formed and fabricated to operate at close bearing tolerances one to another.
		The greatest difference in wire ropes are found in the number of strands, the construction of strands, the size of the core, and the lay direction of the strand versus the core.
		Wire ropes are usually made of Extra Improved Plow Steel (EIPS) or Extra Extra Improved Plow Steel (EEIPS) One cannot determine the Grade of a wire rope by its feel or appearance.

		Wire Ropes are made with either fiber core or steel wire core.
		The fleet angle is the angle formed between the rope running to or from the extreme left or right of the drum and a line drawn from the center of the sheave normal to the axis of the drum.
		Before installing any wire rope that winds onto a drum, the fleet angle should be checked and if found improper, conditions should be corrected.

	History of the Atlantic Cable & Submarine Telegraphy - Wire Rope
		The first wire ropes were made with iron wire, using the same manufacturing methods as for hemp rope.
		By 1834 wire ropes developed by the German engineer Wilhelm Albert were being used in the mines in Germany's Upper Harz district, and it was estimated that the additional manufacturing cost was more than covered by the much longer life of the wire rope over traditional hemp ropes.
		An important feature of Newall's wire rope was a central core of hemp or other flexible material, which ensured that the individual wires and strands were held equidistant from their respective centers to ensure equal stress on each wire.

	Modern History of Wire Rope
		The first operative wire ropes of the modern era, employed in vertical shafts as hoisting cables in the Harz Mountain silver mines of Germany from 1834 to 1854, were not very complicated inventions.
		Roebling's ropes, however, were made entirely of wire, utilizing a core that was identical to the six outer strands, each comprised of 19 wires.
		Thomas Seale's patented form of wire rope is also widely-used, particularly in any kind of application where severe abrasion is encountered, and John Roebling's three-size Warrington construction remains popular for small-diameter ropes where the filler wire principle cannot be applied.

		Mismatching between new wire rope size and worn sheave groove causes a pronounced vibration problem.
		The greater the groove wear, the smaller the sheave radius and the more the rope must move to keep up with the ropes in less worn grooves.
		Lubrication is necessary to reduce friction between the wires, prevent rouge and rust, reduce sheave wear and slow rope fatigue due to repeated bending.
