15、11 Copyright ASME International Provided by IHS under license with ASMENot for ResaleNo reproduction or networking permitted without license from IHS-,-,-FOREWORD This is a revision of A90.1, Safety Code for Manlifts, which was originally drawn up and approved in 1949 and reaffirmed in 1956. The ori
16、ginal Sectional Committee consisted of 19 members representing manufacturers, users, insurance groups, enforcement officials, and indepen- dent specialists. Work was started in 1966 on a revision of this Standard. Each provision of the original code was carefully evaluated in the light of considerab
17、le practical field experience. A draft revision was completed in 1967 and approved by letter bailot in 1968. The USA Standards Institute (now called the American National Standards Institute, Inc.) approved the revised standard on February 7, 1969. Prompted by several serious manlift accidents, the
18、Committee, through correspondence in 1970, considered additional changes to the 1969 standard. Subsequently, in 1972, the Committee issued ANSI A90.la-1972, a supplement to ANSI Standard A90.1-1969. In 1972, new Committee officers were appointed and Committee membership was expanded to include new m
19、embers, many of whom have since made significant contributions to the work of the A90 Committee. Due to changes in technology and the desire to maximize manlift safety, the Committee set about the task of totally revising the A90.1 Standard. This was accomplished only with a great deal of individual
20、 member research and study, coupled with numerous meetings of the entire committee. After three years of concentrated work, the Committee approved by ballot, in 1976, a completely revised draft of the A90.1 Standard. Subsequently, this draft was approved by the American National Standards Institute,
21、 Inc., for issuance as American National Standard In 1981, the A90 Committee was converted from an American National Standards Committee to an ACME Accredited Organization Committee, operating under procedures developed by the ACME and accredited by ANSI. Several new members were added to the Commit
22、tee in this process. After several years of work, a revision to ANSI A90.1-1976 was approved by the A90 Committee and the sponsor organization, and was designated an American National Standard by the American National Standards institute, Inc., on September 10,1985. This revision was approved by the
23、 American National Standards institute on August 14,2003.

As such, users of this Standard may inter- act with the Committee by requesting interpretations, proposin
28、g revisions, and attending Committee meetings. Correspondence should be addressed to: Secretary, A90 Standards Committee The American Society of Mechanical Engineers Three Park Avenue New York, NY 10016 Proposed Revisions. Revisions are made periodically to the standard to incorporate changes that a
29、ppear necessary or desirable, as demonstrated by the experience gained from the application of the standard. Approved revisions will be published periodically. The Committee welcomes proposals for revisions to this Standard. Such proposals should be as specific as possible: citing the paragraph numb
30、er(s), the proposed wording, and a detailed description of the reasons for the proposal, including any pertinent documentation. Interpretations. On request, the A90 Committee will render an interpretation of any requirement of the standard. Interpretations can only be rendered in response to a writ-
31、 ten request sent to the Secretary of the Standards Committee. mended that the inquirer submit his/her request in the following format: Subject: Edition: Question: The request for interpretation should be clear and unambiguous. It is further recom- Cite the applicable paragraph number(s) and provide
32、 a concise description. Cite the applicable edition of the standard for which the interpretation is being requested. Phrase the question as a request for an interpretation of a specific requirement suitable for general understanding and use, not as a request for an approval of a proprietary design o
33、r situation. Requests that are not in this format may be rewritten in the appropriate format by the Committee prior to being answered, which may inadvertently change the intent of the original request. ACME procedures provide for reconsideration of any interpretation when or if additional informatio
34、n which might affect an interpretation is available. Further, persons aggrieved by an interpretation may appeal to the cognizant ACME committee or subcommittee. ACME does not ”approve,” “certify,” ”rate,” or ”endorse” any item, construction, proprietary device, or activity. Attending Committee Meeti
35、ngs. The A90 Standards Committee regularly holds meet- ings that are open to the public.

40、acture, installation, maintenance, inspection, and operation of manlifts. Manlifts covered by this scope consist of steps (plat- forms) and accompanying handholds mounted on, or attached to, an endless belt operating vertically in one direction only and being supported by, and driven through, pulley
41、s at the top and bottom. These manlifts are intended for conveyance of persons only. It is not intended that this scope cover moving stairways, eleya- tors with enclosed platforms (Paternoster elevators), gravity lifts, or conveyors used only for conveying mate- rials. 1.2 Purpose 1.5 Units of Measu
42、rement (03) This Standard contains SI (metric) units as well as Customary units. The SI units have been directly (softly) converted from the Customary units. 2 REFERENCES This Standard is intended for use in conjunction with the following American National Standards.
