Standard for Elevator Suspension, Compensation, and Governor Systems
|Publication Date:||6 August 2018|
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 11∕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 dimensions 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.
