Safety rules for the construction and installation of lifts - Lifts for the transport of persons and goods - Part 20: Passenger and goods passenger lifts

This standard specifies the safety rules for permanently installed new passenger or goods passenger lifts, with traction, positive or hydraulic drive, serving defined landing levels, having a car designed for the transportation of persons or persons and goods, suspended by ropes, chains or jacks and moving between guide rails inclined not more than 15° to the vertical. In addition to the requirements of this standard, supplementary requirements shall be considered in special cases (use of lifts by persons with disabilities, in case of fire, potentially explosive atmosphere, extreme climate conditions, seismic conditions, transporting dangerous goods, etc.).

Sicherheitsregeln für die Konstruktion und den Einbau von Aufzügen - Aufzüge für den Personen- und Gütertransport - Teil 20: Personen- und Lastenaufzüge

1.1   Diese Norm legt die Sicherheitsregeln für dauerhaft eingebaute neue, elektrisch betriebene Personen- oder Lastenaufzüge fest, die einen Treibscheiben-, Trommel,-Ketten- oder hydraulischen Antrieb haben, festgelegte Ebenen bedienen und einen Fahrkorb besitzen, der, an Seilen oder Ketten aufgehängt oder von Hebern getragen, für den Transport von Personen oder Personen und Lasten bestimmt ist und der sich zwischen Führungen, die nicht mehr als 15° gegen die Vertikale geneigt sind, bewegt.
1.2   Zusätzlich zu den Anforderungen dieser Norm müssen in speziellen Fällen weitere Anforderungen (Nutzung der Aufzüge von Personen mit Behinderungen im Brandfall, explosionsgefährdete Atmosphäre, extreme klimatische Verhältnisse, Erdbebenbedin¬gungen, Transport gefährlicher Güter usw.) berücksichtigt werden.
1.3   Diese Norm gilt nicht für
a)   Aufzüge mit
1)   anderen als den in 1.1 genannten Antrieben,
2)   Nenngeschwindigkeiten ≤ 0,15 m/s;
b)   Hydraulikaufzüge
1)   mit einer Nenngeschwindigkeit über 1 m/s,
2)   bei der die Einstellung für Druckbegrenzungsventil (5.9.3.5.3) oberhalb von 50 MPa liegt;
c)   neue Personen- oder Lastenaufzüge in bestehenden Gebäuden ), bei denen unter Umständen infolge von Einschränkungen, die sich aus baulichen Zwängen ergebenen, einige Anforderungen von EN 81 20 nicht erfüllt werden können und bei denen EN 81 21 berücksichtigt werden sollte;
d)   Hebezeuge, wie Umlaufaufzüge, Schachtförderanlagen, Bühnenaufzüge, Einrichtungen mit automa¬tischer Beladung, Kübelaufzüge, Bauaufzüge, Schiffsaufzüge, Bohrplattformen auf See, Bau- und Instand-haltungseinrichtungen oder Aufzüge in Windenergieanlagen;
e)   wesentliche Änderungen (vergleiche Anhang C) an einem Aufzug, der vor dem Inkrafttreten dieser Norm errichtet wurde;
f)   Sicherheit während des Transports, der Errichtung, einer Reparatur und beim Ausbau von Aufzügen.
Dafür kann jedoch sachdienlich von dieser Norm ausgegangen werden.
Lärm und Schwingungen werden in dieser Norm nicht behandelt, weil sie nicht in solchen Größenordnungen ermittelt werden, die in Bezug auf die sichere Benutzung und Wartung von Aufzügen als gefährdend eingestuft werden könnten (siehe auch 0.4.2).
1.4   Diese Norm gilt nicht für Personen- und Lastenaufzüge, die vor ihrer Veröffentlichung errichtet wurden.

Foreword

This document (EN 81-20:2014) has been prepared by Technical Committee CEN/TC 10 “Lifts, escalators

and moving walks”, the secretariat of which is held by AFNOR.

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

text or by endorsement, at the latest by February 2015 and conflicting national standards shall be withdrawn

at the latest by August 2017.

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 for identifying any or all such patent rights.

This document, in conjunction with EN 81-50:2014, supersedes EN 81-1:1998+A3:2009 and EN 81-

2:1998+A3:2009.

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, which is an integral part of this document.

This standard is the culmination of the progressive development of the EN standards for lifts. Previous

versions of the EN 81-1 and EN 81-2 standards incorporated into EN 81-20 and EN 81-50 include:

— EN 81-1:1985, Safety rules for electric lifts
— EN 81-1:1998, Safety rules for electric lifts
— EN 81-1:1998, Corrigendum No 1:1999;

— EN 81-1:1998/A1:2005, incorporating programmable electronic system in safety related applications for

lifts;
— EN 81-1:1998/A2:2004, incorporating machine-room-less lifts;
— EN 81-1:1998+A3:2009, Incorporating unintended car movement with open doors;
— EN 81-2:1987, Safety rules for hydraulic lifts
— EN 81-2:1998, Safety rules for hydraulic lifts
— EN 81-2:1998, Corrigendum No 1:1999;
