This standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”, Directive 95/16/EC, and which apply to machines that are either first placed on the market or commissioned within the EEA. This

8、standard serves to facilitate proof of compliance with the essential requirements of that directive. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirem

9、ents of the Lifts Directive (“presumption of conformity”). The European Standards referred to in this document have been published as DIN EN or DIN EN ISO Standards with the same number.

This Euro

24、pean Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2014, and conflicting national standards shall be withdrawn at the latest by May 2014. Attention is drawn to the possibility that some of the elements of

25、 this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential

26、requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. This document is part of the EN 81 series of standards: “Safety rules for the construction and installation of lifts”. This is the first edition of this Europ

27、ean Standard. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedoni

DIN EN 81-77:2014-02 EN 81-77:2013 (E)5 Introduction The lifts concerned

29、and the extent to which hazards, hazardous situations and events are covered, are indicated in the scope of this document. This document is a Type C Standard as stated in EN ISO 12100. When the provisions of this C standard are different from those which are stated in type A or B standards, the prov

30、isions of this document take precedence over the other standards, for lifts that have been designed and built according to the provisions of this document. The objective of this standard is to define additional safety rules related to passenger and goods/passenger-lifts with a view to safeguarding p

31、ersons and objects against the risks described below associated with the use, maintenance, inspection and emergency operation of lifts subject to seismic conditions. The aim of this European Standard is to: avoid loss of life and reduce the extent of injuries; avoid people trapped in the lift; avoid

32、 damage; avoid environmental problems related to oil leakage; reduce the number of lifts out of service. It is assumed that negotiations have been made for each contract between the customer and the supplier/installer about the design acceleration (ad) to be considered and the most effective positio

33、n of the seismic detection system, if any, and of the primary wave detection system, if any. The building designer or the lift owner should provide the design acceleration (ad) which will be documented in the information for the owner provided by the installer. This European Standard covers only the

34、 effects of earthquakes and not the nature of them. DINEN 81-77:2014-02EN 81-77:2013 (E)6 1 Scope This European Standard specifies the special provisions and safety rules for passenger and goods passenger lifts where these lifts are permanently installed in buildings that are in compliance with EN 1

35、998-1 (Eurocode 8). This standard defines additional requirements to EN 81-1 and EN 81-2. It applies to new passenger lifts and goods passenger lifts. However, it may be used as a basis to improve the safety of existing passenger and goods passenger lifts. It does not apply to seismic lift category

36、0 as defined in Table A.1. This European Standard does not address other risks due to seismic events (for example fire, flood, explosion). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For d

37、ated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

40、 and definitions For the purposes of this document, the terms and definitions given in EN 81-1:1998+A3:2009 and EN 81-2:1998+A3:2009 and the following apply. 3.1 snag point point of interference between flexible elements (for example ropes, chains, travelling cable, etc.) and fixed elements (for exa

42、 seismic lift categories lifts have been divided into categories, taking into account the design acceleration (ad) Note 1 to entry: Table A.1 shows the seismic lift categories. 3.4 primary wave compressional waves that are longitudinal in nature Note 1 to entry: Earthquake advance warning is possibl

43、e by detecting the non-destructive primary waves that travel more quickly through the Earths crust than do the destructive secondary waves. The amount of advance warning depends on the delay between the arrival of the primary wave and other destructive waves, generally in the order of seconds for di

44、stant, large quakes. 3.5 secondary wave shear waves that are transverse in nature, its motion being perpendicular to the direction of wave propagation Note 1 to entry: Secondary waves move through solids, unlike surface waves. They are destructive and arrive later than primary waves. 3.6 seismic tri
