1.3.1 Descriptions of Terms Specific to Rope ELements
1.3.1.1 Stranded SteeL Wire Rope. An assembly of strands laid helically in one layer around a core. See Figure L3L1-L
1.3.1.2 Wire. A single continuous length of steel with a circular uniform cross-section cold drawn from a rod.
1.3.1.2.1 Finish and QuaLity of Coating. The condition of the surface finish of the wire, e.g.. uncoated or metallic coated (zinc or zinc alloy) shall comply with the following:
(a) lincoated Wire. Carbon steel wire that does not have a metallic coating; formerly referred to as bright wire.
(b) Metallic Coated Wire. Carbon steel wire that has a metallic coating.
(1) FInal-Galvanized Wire. Coated carbon steel wire with a zinc coating applied after the final wire drawing operation.
(2) Drawn-Galvanized Wire. Coated carbon steel wire with a zinc coating applied prior to the final wire drawing operation.
(3) Final-Coated Zn-SAl-MM Wire. Coated carbon steel wire with a zinc-aluminum alloy (mischmetal) coating applied after the final wire drawing operation.
(4) Drawn.Zn.5A1.MM Wire. Coated carbon steel wire with a zinc-aluminum alloy (mlschmetal) coating applied prior to the final wire drawing operation.
1.3.1.2.2 Function
(a) Load-Bearing Wires (Main Wires). Those wires In a rope that are considered as contributing toward the breaking force of the rope.
(b) Non-Load-Bearing Wires. Those wires in a rope that are considered as not contributing towards the breaking force of the rope.
(C) Filler Wires. Comparatively small wires used in certain constructions to create the necessary number of interstices for supporting the next layer of covering wires.
d) Seizing (Serving) Wires or Strands. Those single wires or strands used for making a close-wound helical serving to retain the elements of a rope in their assembled position.
1.3.1.2.3 Position
(a) Center Wire. Wire positioned at the center of a strand of a stranded rope.
(b) Inner Wire. All wires except center, filler, core, and outer wires of a stranded rope.
(c) Outer Wire, All wires in the outer layer of the strand of a stranded rope.
(1) Crown Wire. The visible portion of the helically laid outer wire that contacts the wear surfaces.
(2) Valley Wire. The visible portion of the helically laid outer wire that does not contact the wear surfaces.
(d) Core Wire. All wires comprising the core of a stranded rope, where applicable.
1.3.1.2.4 Layer of Wires. An assembly of wires having one pitch diameter. The exception is a Warrington layer comprising large and small wires where the smaller wires are positioned on a larger pitch circle than the larger wires. The first layer of wires is that which is laid over the strand center wire. Filler wires do not constitute a separate layer.
1.3.1.3 Strands
1.3.1.3.1 Strand. An element of rope normally consisting of an assembly of wires of appropriate shape and dimensions laid helically in one or more layers around a center wire.
1.3.1.3.2 Shape of Cross-Section
(a) RoundStrand. Strand havinga perpendicular cross- section that is approximately the shape of a circle. See Figure 1.3.1.3.2-1.
(b) Compacted Round Strand. A round strand that has been subjected to a compacting process such as drawing. rolling, or swaging. See Figure 1.3.1.3.2-2.ASME A17.6 pdf download.
