24、x 84vFOREWORDThe American Society of Mechanical Engineers (ASME) has published since 1921 a safety codefor elevators, escalators, and related equipment. The following is a brief history of how the variouseditions of this Code addressed the matter of retroactive requirements for existing installation

25、s.The 1921 edition did not differentiate between new and existing installations.The second edition (1925) and third edition (1931) contained the following statements in theirIntroductions:“New and Old Installations. After the date on which the Code becomes effective, allnew construction and installa

26、tions shall conform to its provisions. Equipment installedprior to that date need not, however, be modified to conform to its rules except whererequired by the key number opposite the rule. Reference figures attached to the variousrules or paragraphs indicate when such rules or paragraphs become eff

27、ective whenapplied to existing installations as follows:Key to Index Figures(0) To be applied immediately.(1) Not to be applied to existing installations.(2) To be applied to existing installations only to the extent ordered by the administrativeauthority.(3) To be applied to existing installations

28、when next renewal of cables or other partsaffected is made.(6) To be applied to existing installations six months after the adoption of this Code.(12) To be applied to existing installations 1 year (12 months) after the adoption of thisCode.(24) To be applied to existing installations two years afte

29、r the adoption of this Code.”This practice was discontinued with the fourth edition. Quoting from ASA A17.11937:“This Edition of the Code makes no reference to the application of the individual rulesto Existing Installations, and the key numbers in the previous Edition have been omitted.This matter

30、is left to the authorities drafting legal regulations, who are familiar with thelocal conditions. A too extensive retroactive application is not advisable in any case.The Code contains many rules intended to obviate minor hazards which can be easilyeliminated in a new installation, but the change of

31、 an existing installation might involvea financial outlay entirely out of proportion to the benefits secured.“The Sectional Committee recommends that rules for hoistway-door interlocks, car-gate contacts, hoistway limit switches, and the entire Part VI (Inspection, Maintenance,and Operation) be made

32、 applicable to every installation already existing at the time ofthe adoption of the Code, and that provisions be made also to secure adequate under-car safeties for such installations.”This practice remained essentially unchanged through all later editions of the Code. Only therequirements for insp

33、ection, maintenance, alteration, repair, and replacement apply retroactivelyto existing installations. Quoting from the Preface of ANSI/ASME A17.11981:“Not all of the Rules of the Code apply to equipment installed prior to its adoptionby jurisdictional authorities, but those which do apply to existi

34、ng as well as to newinstallations are outlined under Scope in the Introduction.“The Code contains many Rules intended to obviate hazards which can be avoidedin new installations; but, if such Rules were made to apply to existing installations, theywould entail financial outlay out of proportion to t

35、he benefits derived.“In view of past accident experience resulting in serious injuries at hoistway and carentrances, it is recommended that, as a minimum, the Rules covering safety requirementsvifor hoistway and car doors in this Code be made to also apply to existing elevatorinstallations.“The acci

36、dent experience on elevators has also indicated that accidents occur on theolder existing equipment, especially with a winding-drum-type machine and where thecar safety device and the terminal stopping devices are either absent or inadequate. Itis, therefore, recommended that adequate under-car safe

37、ties and terminal stoppingdevices be required for existing installations as well as new installations.“On the basis of experience supported by accident records, the jurisdictional authorityadopting the Code should decide on what requirements, if any, are to be applied toexisting installations.”Numer

38、ous state and local jurisdictions had taken this advice and developed their own codes forexisting installations. The need for a nationally recognized consensus code for existing installationsbecame evident and the ASME A17 Elevator and Escalator Committee undertook the task andissued the first editi

39、on of the A17.3 Safety Code for Elevators and Escalators in 1986.The second edition of the Code incorporated the revisions in A17.3a1989 as well as additionalrevisions that appear for the first time in this edition.The third edition of the Code incorporated the changes made in A17.3a1991 and A17.3b1

40、992as well as the revisions shown in the Summary of Changes. Part VII, Hand Elevator, and Part VIII,Sidewalk Elevator, appear for the first time in this edition.The fourth edition of the Code incorporated the changes made in A17.3a1994 and A17.3b1995as well as the revisions shown in the Summary of C

41、hanges. Part X, Private Residence Elevators,and Nonmandatory Appendix D appear for the first time in this edition.The fifth edition of the Code incorporated the changes made in A17.3a2000 as well as therevisions shown in the Summary of Changes.This sixth edition of the Code incorporated the changes

42、made in A17.32002 as well as therevisions shown in the Summary of Changes.The seventh edition of the Code incorporated the changes made in A17.32005 as well as therevisions shown in the Summary of Changes.The eighth edition of the Code incorporated the changes made in A17.32008 as well as therevisio
