At the time, the A17 Editorial Committ

25、ee was charged with a total editorial review of the A17.1 Code for the 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 the content of a Rule, it was essential tha

26、t the Committee members had a clear understanding of the technical requirements and their intent. Bill Crager had a long history as a member of the A17 Committee, including 15 years as Committee Chairman. At the meetings, the members wouldlooktoBillforhisrecollectionofwhyaRulewasintheCode.Billposses

27、sedanencyclopedic knowledge of the history of A17 requirements. His typical response would start by stating, “At the (date)A17Meeting,theCommittee approved the Rulefor the following reason.” At our next meeting, Bill would arrive with documents from his home file backing up his recollection includin

28、g the meeting dates. I quickly came to the conclusion that the “Bill Cragers” on the A17 Committee were mostly retired or would be retiring from Committee activities over the next few years. Their expansive knowledge of the past committee work and the rationale for the A17.1 Rules would no longer be

29、 available. This would be a loss not only to the A17 Committee but also 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 NEC Handbook was an invaluable supporting document for the NEC . I approached MelGreen,thendirectorofASMEC

30、odesandStandards,withaproposaltowriteanASMEA17.1 Handbook. He thought the idea had merit, and the first edition of the A17.1 Handbook was published at the time of publication of the 1981 edition of the A17.1 Code. A new edition of the Handbook was published thereafter with each new edition of the A1

31、7.1 Code and later the A17.1/B44 Code, with this being the 11th edition of the ASME A17.1/CSA B44 Handbook. As I gaze into my crystal ball at my future, it looks like this may be the last edition of the Handbook I will author. Time will tell, but if I decide to completely retire, I trust ASME will c

32、ontinue to publish new editions of the Handbook with each new edition of the ASME A17.1/ CSA B44 Code. Ed Donoghue viiFOREWORD TheASMEA17.1/CSAB44SafetyCodeforElevators and Escalators is written by a committee of technically qualifiedpersonswithaconcernandcompetenceinthe subject withinthe Committees

33、scope anda willingness to participate in the work of the Committee. The ASMEA17StandardsCommitteeisrestrictedtoamaxi- mum of 35 members of which no more than one-third can be from any single interest category. This require- ment serves to assure balance in the consensus process. In addition, there a

34、re over 300 members serving on the RegulatoryAdvisoryCouncil,NationalInterestReview Group, Technical Committees, Administrative Committees, and Ad Hoc Committees. Technical revi- sions to ASME A17.1/CSA B44 are also submitted to theCSAB44TechnicalCommitteefortheirconcurrence. ThisHandbookincorporate

35、stheharmonizationofthe ASME A17.1, Safety Code for Elevators and Escalators and CSA B44, Safety Code for Elevators. Since 2000, editions oftheCSAB44andASMEA17.1Codeshavebeenidenti- cal,exceptforapplicationdeviationsnotedinCSAB44. Starting with the ASME A17.1-2007/CSA B44-07, a sin- gleCodebookhasbee

36、npublishedforuseintheUnited States and Canada. A joint effort of the CSA B44 Technical Committee and the ASME A17 Standards Committee to harmonize requirements between CSA B44 and ASME A17.1 was started in the mid-1990s. The harmonization process compared and studied differences between the twocodes

37、 over a num- ber of years through discussions by joint ASME/CSA workinggroups.Aharmonizedrequirementwasformu- lated and proposed for review and approval through formal balloting by both the ASME A17 Standards Committee and CSA B44 Technical Committee. If any member did not approve a proposed require

38、ment, the membersrationale fordisapproval wasreturned to the workingcommitteeforresolution.Theworkingcommit- tee either revised the proposal or provided a reason for rejectingthecomment.Therevisedproposalorrejection was once again balloted until negatives were resolved ortheChairmanoftheASMEA17Stand

39、ardsCommittee ruledconsensushadbeenachieved.Manyrequirements went through multiple ballots before a consensus was achieved. As a result, requirements in the ASMEA17.1-2000andCSAB44-00andlatereditionsof the Code are different from corresponding Rules and Clauses in the previous editions of ASME A17.1

40、 and CSA B44. The harmonization process identified techni- cal and editorial problems with requirements in both codes and in such cases formulated new requirements. The ASME A17 and CSA B44 Committees recognized viii that not all requirements could be fully harmonized, in particular requirements bas

41、ed on, or which depended on,othernationalcodesorregulations,suchasbuilding, electrical, and fire codes. In such cases, two separate requirements were formulated, one for “jurisdictions enforcing NBCC” (meaning National Building Code of Canadaor“NBCC”forshort)andanotherfor“jurisdic- tionsnotenforcing

42、NBCC”(meaningtheUnitedStates). In cases where no agreement on a requirement could be achieved or the publication schedule precluded con- tinuation of discussions, the CSA B44 Technical Committee created Canadian exceptions from the ASME A17.1 requirements, known as Canadian devia- tions. These Canad

43、ian deviations appeared in the CSAB44-00andCSA-B44-04ElevatorSafetyCode.Both committees continue the harmonization process and endeavor to reduce the number of Canadian deviations infutureeditions.InJanuary2006,thelistofdeviations hadshrunktothepointwheretheASMEA17Standards Committee felt they could

44、 all be incorporated in the next edition of the ASME A17.1 Code with an objective of publishing a single Safety Code for Elevators and EscalatorsforuseinboththeUnitedStatesandCanada. That objective was met with the publication of ASME A17.1-2007/CSA B44-07. ASMEandCSArecognizethattheCodemustbewrit-

45、ten in a form suitable for enforcement by state, munici- pal, and other jurisdictional or regulatory authorities often referred to in the United States as “Authorities Having Jurisdiction (AHJ)” and in Canada as “Regulatory Authorities (RA)”; and as such, the text is concise, without examples or exp

46、lanations. It is also recognized that this Code cannot cover every situation nor can it cover new technology before it is developed andfieldexperienceisgained.Forthesereasons,ASME agreed that a handbook would be useful to augment the Code by providing a commentary on the Code requirements. This Hand

47、book contains rationale for the ASME A17.1/CSA B44 Code requirements along with explanations, examples, and illustrations of the imple- mentation of requirements. In addition, it contains excerptsfromothernationallyrecognizedstandardsref- erenced by the Code. This information is intended to provide

48、users of the ASME A17.1/CSA B44 Code with a better understanding of, and appreciation for, the requirements. The net result should be increased safety for owners, manufacturers, installers, maintainers, con- sultants, the inspection community, and users ofequip- ment covered by the ASME A17.1/CSA B4

49、4 Code.Commentary in this Handbook was compiled from ASME A17 Committee minutes, correspondence, and interpretations, as well as conversations with past and present ASME A17 and CSA B44 committee members. The original intent for requirements in ASME A17.1 andCSAB44CodesmaybeobscureintheCommittees records. Therefore, this Handbook will convey, through text, examples of calculations, tables, and illustrations, theendresultofCoderequirementsasappliedtoequip- ment installed today where the original intent cannot befound.Itshouldnotbeconstruedthatexamples and illustrations in thi
