This Standard has been devel-oped by the American Society of Mechanical Engineers(ASME) to provide guidance to the elevator
21、industry forthe appropriate use of means for suspension, compensa-tion, and governors. The first edition includes standardsfor three technologies for elevators, namely: steel wireropes, aramid fiber ropes, and noncircular elastomericcoated steel suspension members. Uniform standardsfor these importa
22、nt items are necessary to ensure consist-ent levels of safety and to provide guidance for themanufacturers of these items as well as the designers,manufacturers, installers, maintainers, and inspectors ofelevator equipment.As other technologies emerge and are deemed to besuitable for similar applica
23、tions, this Standard will beexpanded to include criteria for their usage.In developing this Standard, experts were assembledfrom the steel wire rope, aramid fiber rope, and noncir-cular elastomeric coated steel suspension members engi-neering and manufacturing fields. Relevant existingstandards were
24、 studied during the development of thisStandard and are referenced where appropriate. Thescope of this Standard covers North American and inter-national requirements in a comprehensive manner anddoes not conflict with existing American or internationalstandards. This Standard is intended to be used
25、in con-junction with the ASME A17.1/CSA B44, Safety Codefor Elevators and Escalators, and related Codes andstandards.Steel Wire Rope for ElevatorsSteel wire rope has been used for many years in theelevator industry, for suspension, compensation, andgovernor applications.Due to the large range of app
26、lications in this diversemarket, many variations of steel wire ropes are in currentuse. Examples include rope of regular and lang lay, leftand right lay, preformed and nonpreformed. Such ropesmay be of a variety of wire materials, from iron to hightensile steel and may be of corrosion resistant cons
27、truc-tion. Various core materials including natural and syn-thetic fiber and steel may also be used. Nominal imperialdimensions as well as SI dimensional ropes are used.vIn recognition of the importance of this vital elevatorcomponent and the unique practices of the NorthAmerican industry, this Stan
28、dard was developed. ThisStandard covers the current applications and providesstrength and material criteria as well as testing, compli-ance, inspection, replacement, and ordering informa-tion. Imperial and SI dimensions are addressed in theStandard. The purpose of this Standard is to enhancepublic s
29、afety and to provide guidance to manufacturersand users of steel wire rope.Aramid Fiber Ropes and Elastomeric Coated SteelBeltsWith the appearance in the market place of new sus-pension and compensation means technologies, such asaramid fiber ropes and noncircular elastomeric coatedsteel suspension
30、members for elevators, the need forstandards that will ensure the safe application of theseitems became evident. This Standard addresses theseimportant technologies.In developing the standards, extensive test resultswere studied and the properties and durability of thenew suspension and compensation
31、 means were exam-ined. The work included visits to major laboratories atwhich all aspects of the noncircular elastomeric coatedsteel suspension members were tested.The work included a visit to the factory of a majormanufacturer of aramid fiber and technical presenta-tions by experts in this technolo
32、gy. The test work of amajor laboratory and field results from the applicationof aramid fiber rope on elevators were also studied.Test facilities where the noncircular elastomeric coatedsteel suspension members were extensively tested onelevators were also visited. In addition, technical presen-tatio
33、ns on the noncircular elastomeric coated steel sus-pension members regarding their construction andtesting took place.Tests on both ramid fiber ropes and noncircular elasto-meric coated steel suspension members included life,durability, resistance to damage, traction, replacementcriteria, effects of
34、 the environment, and many other crite-ria. This work was extremely helpful in developing thestandards and building confidence in the validity of therequirements.ASME A17.6-2010 was approved by the AmericanNational Standards Institute on March 17, 2010.ASME A17 ELEVATORAND ESCALATOR COMMITTEE(Januar

40、NationalStandards Institute (ANSI). Safety codes and standardsare intended to enhance public health and safety. Revi-sions result from committee consideration of factorssuch as technological advances, new data, and changingenvironmental and industry needs. Revisions do notimply that previous edition
41、s were inadequate.This Standard is referenced by and intended to beused in conjunction with ASME A17.1/CSA B44, SafetyCode for Elevators and Escalators, and related Codesand standards. Written inquiries regarding this Standardshould be addressed to the Secretary of the ASME A17Standards Committee.NO
42、TE: Referenced Codes, Standards, and Test Methods thatappear with no date indicated shall be the edition in effect at thetime of publication of this Standard.FORM AND ARRANGEMENTThis Standard consists of three parts, each covering aspecific technology related to elevator suspension andcompensation m
43、eans and governor ropes. TheForeword, Preface, and Notes that are included in thisdocument, and the Interpretations that are provided asa separate document are not part of this AmericanNational Standard. They are advisory in nature and areintended for clarification only.SCOPEThis Standard covers the
44、 means and members of sus-pension, compensation, and governor systems for eleva-tors within the scope of ASME A17.1/CSA B44.xiiNOTE: It must be determined by the individual workingcommittees as to the level of appropriateness of applying the NewTechnologies in their particular applications.This Stan
45、dard includes the material properties,design, testing, inspection, and replacement criteria forthese means.
