23、ents 568Index 569The Author 592vINTRODUCTIONIn 1976 I was appointed to the A17 Editorial Committee with Al Land (Chair), William “Bill”Crager (A17 Chair), and Manuel Gutierrez (ASME Secretary). At the time, the A17 EditorialCommittee was charged with a total editorial review of the A17.1 Code for th

24、e 1978 edition.Every Rule was scrutinized and editorially revised for clarification when appropriate.The committee met weekly for this massive project. To avoid unintentionally changing thecontent of a Rule, it was essential that the committee members had a clear understanding of thetechnical requir

25、ements and their intent. Bill Crager had a long history as a member of theA17 Committee, including 15 years as Committee Chairman. At the meetings the members wouldlook to Bill for his recollection of why a Rule was in the Code. Bill possessed an encyclopedicknowledge of the history of A17 requireme

26、nts. His typical response would start by stating “atthe (date) A17 Meeting the Committee approved the Rule for the following reason.” At our nextmeeting Bill would arrive with documents from his home file backing up his recollection including the meeting dates.I quickly came to the conclusion that t

27、he “Bill Cragers” on the A17 Committee were mostlyretired or would be retiring from committee activities over the next few years. Their expansiveknowledge of the past committee work and the rationale for the A17.1 Rules would no longerbe available. This would be a loss to not only the A17 Committee

28、but to the users of the Code.I concluded that a Handbook for A17.1 would be an invaluable addition to the A17.1 Code,as the NECHandbook was an invaluable supporting document for the NEC. I approachedMel Green, then director of ASME Codes and Standards, with a proposal to write an ASME A17.1Handbook.

29、 He thought the idea had merit, and the first edition of the A17.1 Handbook waspublished at the time of publication of the 1981 edition of the A17.1 Code. A new edition of theHandbook was published thereafter with each new edition of the A17.1 Code and later theA17.1/B44 Code, with this being the 10

30、th edition of the ASME A17.1/CSA B44 Handbook.Ed DonoghueviFOREWORDThe ASME A17.1/CSA B44 Safety Code for Elevatorsand Escalators is written by a committee of technicallyqualified persons with a concern and competence in thesubject within the Committees scope and a willingnessto participate in the w

31、ork of the committee. TheASME A17 Standards Committee is restricted to a maxi-mum of 35 members of which no more than one-thirdcan be from any single interest category. This require-ment serves to assure balance in the consensus process.In addition, there are over 300 members serving on theRegulator

32、y Advisory Council, National Interest ReviewGroup, Technical Committees, AdministrativeCommittees, and Ad Hoc Committees. Technical revi-sions to ASME A17.1/CSA B44 are also submitted tothe CSA B44 Technical Committee for their concurrence.This Handbook incorporates the harmonization of theASME A17.

33、1, Safety Code for Elevators and Escalators andCSA B44, Safety Code for Elevators. Since 2000, editionsof both CSA B44-00 ASME and A17.12000 Codes areidentical, except for application deviations noted inCSA B44. Starting with the ASME A17.1/CSA B44-2007,a single Code book has been published for use

34、in theU.S. and Canada. A joint effort of the CSA B44 TechnicalCommittee and the ASME A17 Standards Committeeto harmonize requirements between CSA B44 andASME A17.1 was started in the mid-1990s. Theharmonization process compared and studied differ-ences between the two codes over a number of yearsthr

35、ough discussions by joint ASME/CSA workinggroups. A harmonized requirement was formulated andproposed for review and approval through formal bal-loting by both the ASME A17 Standards Committee andCSA B44 Technical Committee. If any member did notapprove a proposed requirement, the members ratio-nale

36、 for disapproval was returned to the working com-mittee for resolution. The working committee eitherrevised the proposal or provided a reason for rejectingthe comment. The revised proposal or rejection was onceagain balloted until negatives were resolved or theChairman of the ASME A17 Standards Comm

37、ittee ruledconsensus had been achieved. Many requirements wentthrough multiple ballots before a consensus wasachieved. As a result, requirements in theASME A17.1-2000/CSA B44-00 and later editions of theCode are different from corresponding Rules andClauses in the previous editions of ASME A17.1 and

38、CSA B44. The harmonization process identified techni-cal and editorial problems with requirements in bothcodes and in such cases formulated new requirements.The A17 and B44 Committees recognized that not allviirequirements could be fully harmonized, in particularrequirements based on, or which depen

39、ded on, othernational codes or regulations, such as building, electri-cal, and fire codes. In such cases two separate require-ments were formulated, one for “jurisdictions enforcingNBCC” (meaning National Building Code of Canada or“NBCC” for short) and another for “jurisdictions notenforcing NBCC” (

40、meaning the United States).In cases where no agreement on a requirement couldbe achieved or the publication scheduled precluded con-tinuation of discussions, the B44 Technical Committeecreated Canadian exceptions from the ASME A17.1requirements, known as Canadian deviations. TheseCanadian deviations

41、 appeared in the CSA B44-00 and04 Elevator Safety Code. Both committees continue theharmonization process and endeavor to reduce the num-ber of Canadian deviations in future editions. In January2006, the list of deviation had shrunk to the point wherethe ASME A17 Standards Committee felt they could

42、allbe incorporated in the next edition of the ASME A17.1Code with an objective of publishing a single SafetyCode for Elevators and Escalators for use in both theU.S. and Canada. That objective was met with the publi-cation of ASME A17.1/CSA B44-2007.ASME and CSA recognizes that the Code must bewritt

43、en in a form suitable for enforcement by state,municipal, and other jurisdictional or regulatory author-ities often referred to in the United States as “AuthoritiesHaving Jurisdiction (AHJ)” and in Canada as“Regulatory Authorities (RA)”; and as such, the text isconcise, without examples or explanati

44、ons. It is alsorecognized that this Code cannot cover every situationnor can it cover new technology before it is developedand field experience is gained. For these reasons, ASMEagreed that a handbook would be useful to augmentthe Code by providing a commentary on the Coderequirements.This Handbook

45、contains rationale for theASME A17.1/CSA B44 Code requirements along withexplanations, examples, and illustrations of the imple-mentation of requirements. In addition, it containsexcerpts from other nationally recognized standards ref-erenced by the Code. This information is intended toprovide users

46、 of the ASME A17.1/CSA B44 Code witha better understanding of, and appreciation for, therequirements. The net result should be increased safetyfor owners, manufacturers, installers, maintainers, con-sultants, inspection community and users of equipmentcovered by the ASME A17.1/CSA B44 Code.Commentar

47、y in this Handbook was compiled fromASME A17 Committee minutes, correspondence, andinterpretations, as well as conversations with past andpresent ASME A17 and CSA B44 committee members.The original intent for requirements in ASME A17.1and CSA B44 Codes may be obscure in Committeesrecords. Therefore,

48、 this Handbook will convey, throughtext, examples of calculations, tables, and illustrations,the end result of Code requirements as applied to equip-ment installed today where the original intent cannotbe found. It should not be construed that examples andillustrations in this Handbook are the only

49、means ofcomplying with ASME A17.1/CSA B44 Code require-ments, or that all illustrations necessarily represent allrequirements contained in the Code. Some illustrationssimply reflect general industry or specific company prac-tices. With information of this type, it is hoped the readerwill develop a better understanding of, and appreciationfor, requirements in ASME A17.1/CSA B44.Commentary contained in this Handbook is the opin-ion of the author. It does not necessarily reflect the offi-cial position of ASME, the ASME A17 StandardsCommittee for Elevators and Escalators, CSA, or
