This European Standard shall be given the status of a national standard, either by publication of an identical

19、 text or by endorsement, at the latest by May 2014, and conflicting national standards shall be withdrawn at the latest by May 2014.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 this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible

20、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 requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, whi

21、ch 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 European Standard. According to the CEN-CENELEC Internal Regulations, the national standards organizations

22、 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 Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, N

23、etherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 81-77:2013EN 81-77:2013 (E) 5 Introduction The lifts concerned and the extent to which hazards, hazardous situations and events are covered, are indicated in the scope

24、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 provisions of this document take precedence over the other standards, for lifts that have been designed and b

25、uilt 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 persons and objects against the risks described below associated with the use, maintenance, inspection and

26、 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 damage; avoid environmental problems related to oil leakage; reduce the number of lifts out of service.

27、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 position of the seismic detection system, if any, and of the primary wave detection system, if any. The building

28、 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 effects of earthquakes and not the nature of them. BS EN 81-77:2013EN 81-77:2013 (E) 6 1 Scope This Euro

29、pean 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 1998-1 (Eurocode 8). This standard defines additional requirements to EN 81-1 and EN 81-2. It applies to new

30、 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 0 as defined in Table A.1. This European Standard does not address other risks due to seismic events (for e

31、xample 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 dated references, only the edition cited applies. For undated references, the latest edition of the referenc

35、 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 example by guide rail brackets, guide rail clip bolts, fishplates, vanes, and similar devices) 3.2 design acce

36、leration (ad) horizontal acceleration to be used for calculation of forces moments acting on lift systems and arising from seismic events (see Annex B) BS EN 81-77:2013EN 81-77:2013 (E) 7 3.3 seismic lift categories lifts have been divided into categories, taking into account the design acceleration

37、 (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 possible by detecting the non-destructive primary waves that travel more quickly through the Earths crust than do th

38、e 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 distant, large quakes. 3.5 secondary wave shear waves that are transverse in nature, its motion being perpendic

39、ular 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 trigger level seismic acceleration which used to activate a seismic detection system 3.7 seismic mode special mo
