ASME A17.6-2010 pdf download.Standard for Elevator Suspension, Compensation, and Governor Systems.
Part 1 covers the general requirements for the more common types of stranded steel wire ropes for hoisting, compensation, and governor applications on passenger or freight elevators. Included in the scope of this Part are steel wire ropes in various grades and constructions from 4 mm to 38 mm ( 5 ⁄ 32 in. to 1 1 ⁄ 2 in.) manufactured from uncoated wire or metallic coated wire. For specific applications, additional or alternative requirements may apply, provided equivalent safety is maintained. Part 1 covers regular lay and lang lay, preformed and nonpreformed elevator rope in nominal imperial dimen- sions as well as SI dimensions. Various constructions of steel wire rope are covered, i.e., Seale, Warrington, and Filler. Part 1 covers the broad range of wire materials in current use including Iron, Traction, Extra High Strength Traction, 1570 Single, 1180/1770 Dual, 1370/1770 Dual, 1770 Single, 1960 Single, and 2300 Single. Various rope core materials in current use are covered by this Part including natural and synthetic fiber cores and steel cores. This Part covers ropes made from uncoated wires or metallic coated wires (e.g., galvanized). This Part includes criteria for testing and compliance of rope, replacement of rope, and ordering information for steel wire rope. NOTE: Part 1 is written in the combined format, presenting requirements for rope products in both Imperial units, utilized historically in the SI and U.S. Customary units as recognized by current international standards. The values stated in SI (metric) units or Imperial units are to be regarded separately. The values are not exact equivalents; therefore, each system must be used independently of the other.

(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-5Al-MM Wire. Coated carbon steelwire witha zinc-aluminumalloy(mischmetal) coat- ing applied after the final wire drawing operation. (4) Drawn-Zn-5Al-MM Wire. Coated carbon steel wire with a zinc-aluminum alloy (mischmetal) coating applied prior to the final wire drawing operation. 18.104.22.168.2 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) Nonload-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 assem- bled position. 22.214.171.124.3 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.
