14、of A90.1, Safety Code for Manlifts, which was originally drawn up andapproved in 1949 and reaffirmed in 1956. The original Sectional Committee consisted of 19members representing manufacturers, users, insurance groups, enforcement officials, and indepen-dent specialists.Work was started in 1966 on a
15、 revision of this Standard. Each provision of the original codewas carefully evaluated in the light of considerable practical field experience. A draft revisionwas completed in 1967 and approved by letter ballot in 1968. The USA Standards Institute (nowcalled the American National Standards Institut
16、e) approved the revised standard onFebruary 7, 1969.Prompted by several serious manlift accidents, the Committee, through correspondence in1970, considered additional changes to the 1969 standard. Subsequently, in 1972, the Committeeissued ANSI A90.1a-1972, a supplement to ANSI Standard A90.1-1969.I
17、n 1972, new committee officers were appointed and committee membership was expandedto include new members, many of whom have since made significant contributions to the workof the A90 Standards Committee.Due to changes in technology and the desire to maximize manlift safety, the Committee setabout t
18、he task of totally revising the A90.1 Standard. This was accomplished only with a greatdeal of individual member research and study, coupled with numerous meetings of the entireCommittee. After three years of concentrated work, the Committee approved by ballot, in 1976,a completely revised draft of
19、the A90.1 Standard. Subsequently, this draft was approved by theAmerican National Standards Institute for issuance as American National Standard A90.1-1976.In 1981, the A90 Standards Committee was converted from an American National StandardsCommittee to an ASME Accredited Organization Committee, op
20、erating under procedures devel-oped by ASME and accredited by ANSI. Several new members were added to the Committeein this process. After several years of work, a revision to ANSI A90.1-1976 was approved by theA90 Standards Committee and the sponsor organization, and was designated an AmericanNation
21、al Standard by the American National Standards Institute on September 10, 1985.A90.1-2003 was approved by the American National Standards Institute on August 14, 2003.A90.1-2009 was approved by the American National Standards Institute on March 23, 2009. Thisrevision was approved by the American Nat
22、ional Standards Institute on January 13, 2015.ivASME A90 COMMITTEESafety Standards for Manlifts(The following is the roster of the Committee at the time of approval of this Standard.)STANDARDS COMMITTEE OFFICERSJ.

As such, users of this Standard may interact with theCommittee by proposing revisions and attending Committee meetings. Corr
25、espondence shouldbe addressed to:Secretary, A90 Standards CommitteeThe American Society of Mechanical EngineersTwo Park AvenueNew York, NY 10016http:/go.asme.org/InquiryProposed Revisions. Revisions are made periodically to the Standard to incorporate changesthat appear necessary or desirable, as de
26、monstrated by the experience gained from the applicationof the Standard. Approved revisions will be published periodically.The Committee welcomes proposals for revisions to this Standard. Such proposals should beas specific as possible, citing the paragraph number(s), the proposed wording, and a det

31、A90.1-2015SAFETY STANDARD FOR BELT MANLIFTS1 GENERAL1.1 ScopeThis Standard applies to the manufacture, installation,maintenance, inspection, and operation of manlifts.Manlifts covered by this scope consist of steps (plat-forms) and accompanying handholds mounted on, orattached to, an endless belt op
32、erating vertically in onedirection only and being supported by, and driventhrough, pulleys at the top and bottom. These manliftsare intended for conveyance of persons only. It is notintended that this scope cover moving stairways, eleva-tors with enclosed platforms (Paternoster elevators),gravity li
33、fts, or conveyors used only for conveyingmaterials.1.2 PurposeThe purpose of this Standard is to establish safetyrequirements for manlifts. It is intended for use as astandard reference for manlift safety requirements bymanufacturers, architects, plant designers, installers,and consulting engineers,
34、 and for users of manliftsthrough voluntary application and for governmentalauthorities.1.3 Application(a) This Standard applies to manlifts used to carryonly authorized personnel trained in their use. Manliftsshall not be available to the general public.(b) Because of the difficulty in enforcing pa
35、ras. 4.2and 7.1(a), manlifts are not recommended for use onconstruction sites.(c) One year after the date of issuance, all provisionsof this Standard shall apply to both new and existinginstallations, except as noted in individual sections.1.4 ExceptionsIn case of practical difficulty or unnecessary
36、 hardship,the enforcing authority may grant exceptions from theliteral requirements of this Standard or permit the useof alternate methods, but only when it is clearly evidentthat equal safety is thereby secured.NOTE: It is suggested that in cases where exceptions are askedfor, the enforcing authori
