25、book, and the first one not authored by Ed Donoghue. The idea for the Handbook came from Mr. Donoghue and has grown from that simple idea to the valued resource we all know today. The history behind the Handbook is important, so, below, I have included Mr. Donoghues Introduction from the 2013 editio

26、n to provide that background. In 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 Editorial Committee was charged with a total editorial review of the A17.1 Code for the 1978 editi

27、on. 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 that the Committee members had a clear understanding of the technical requirements a

28、nd 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.Billpossessedanencyclopedic knowledge of the history of A17 requirements. His typical respo

29、nse would start by stating, “At the (date) A17 Meeting, the Committee approved the Rule for the following reason.” At our next meeting, Bill would arrive with documents from his home file backing up his recollection including the meeting dates. I quickly came to the conclusion that the “Bill Cragers

30、” 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 available. This would be a loss not only to the A17 Committee but also to t

31、he 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,thendirectorofASMECodesandStandards,withaproposaltowriteanASMEA17.1 Handbook. He thought the id

32、ea 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 A17.1 Code and later the A17.1/B44 Code.EdDonoghue With each passing year, we

33、see experts in the industry retire and we welcome new faces to the Code development process. The Handbook, much like the Code itself, is a living document. Each edition updates and expands upon the information provided in previous edition. I have the privilege of authoring this edition of the Handbo

34、ok and hope to continue the tradition and build on the foundation that Mr. Donoghue and so many others have helped to create. Kevin Brinkman viiFOREWORD The ASME A17.1/CSA B44 Safety Code for Elevators and Escalators is written by a committee of technically qualified persons with a concern and compe

35、tence in the subject within the Committees scope and a willingness to participate in the work of the Committee. The ASME A17 Standards Committee is restricted to a maxi- mum of 35 members of which no more than one-third can be from any single interest category. This require- ment serves to ensure ba

36、lance in the consensus process. In addition, there are over 300 members serving on the Regulatory Advisory Council, National Interest Review Group, Technical Committees, Administrative Committees, and Ad Hoc Committees. Technical revi- sions to ASME A17.1/CSA B44 are also submitted to the CSA B44 Te

37、chnical Committee for their concurrence. This Handbook incorporates the harmonization of the ASME A17.1, Safety Code for Elevators and Escalators and CSA B44, Safety Code for Elevators. Since 2000, editions of the CSA B44 and ASME A17.1 Codes have been identi- cal, except for application deviations

38、noted in CSA B44. Starting with the ASME A17.1-2007/CSA B44-07, a sin- gle Code book has been published for use in the United 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

39、 in the mid-1990s. The harmonization process compared and studied differences between the two codes over a num- ber of years through discussions by joint ASME/CSA working groups. A harmonized requirement was formu- lated and proposed for review and approval through formal balloting by both the ASME

40、A17 Standards Committee and CSA B44 Technical Committee. If any member did not approve a proposed requirement, the members rationale for disapproval was returned to the working committee for resolution. The working commit- tee either revised the proposal or provided a reason for rejecting the commen

41、t. The revised proposal or rejection was once again balloted until negatives were resolved or the Chairman of the ASME A17 Standards Committee ruled consensus had been achieved. Many requirements went through multiple ballots before a consensus was achieved. As a result, requirements in the ASME A17

42、.1-2000 and CSA B44-00 and later editions of the Code are different from corresponding Rules and Clauses in the previous editions of ASME A17.1 and CSA B44. The harmonization process identified techni- cal and editorial problems with requirements in both codes and in such cases formulated new requir

43、ements. The ASME A17 and CSA B44 Committees recognized that not all requirements could be fully harmonized, in viii particular requirements based on, or which depended on, other national codes or regulations, such as building, electrical, and fire codes. In such cases, two separate requirements were

44、 formulated, one for “jurisdictions enforcing NBCC” (meaning National Building Code of Canada or “NBCC” for short) and another for “jurisdic- tions not enforcing NBCC” (meaning the United States). In cases where no agreement on a requirement could be achieved or the publication schedule precluded co

45、n- tinuation of discussions, the CSA B44 Technical Committee created Canadian exceptions from the ASME A17.1 requirements, known as Canadian devia- tions. These Canadian deviations appeared in the CSA B44-00 and CSA-B44-04 Elevator Safety Code. Both committees continue the harmonization process and

46、endeavor to reduce the number of Canadian deviations in future editions. In January 2006, the list of deviations had shrunk to the point where the ASME A17 Standards Committee felt they could all be incorporated in the next edition of the ASME A17.1 Code with an objective of publishing a single Safe

47、ty Code for Elevators and Escalators for use in both the United States and Canada. That objective was met with the publication of ASME A17.1-2007/CSA B44-07. ASME and CSA recognize that the Code must be writ- ten in a form suitable for enforcement by state, munici- pal, and other jurisdictional or r

48、egulatory 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 explanations. It is also recognized that this Code cannot cover every situation nor can it cov

49、er new technology before it is developed and field experience is gained. For these reasons, ASME agreed that a handbook would be useful to augment the Code by providing a commentary on the Code requirements. This Handbook 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 excerpts from other nationally recognized standards ref- erenced by the Code. This information is intended to provide users of the ASME A17.1/CSA B44 Code with a better unde
