This European Standard shall be given the status of a national stan
25、dard, either by publication of an identical text or by endorsement, at the latest by January 2010, and conflicting national standards shall be withdrawn at the latest by January 2010. This document includes Amendment 1, approved by CEN on 2009-06-19. This document supersedes EN 1756-2:2004. The star
26、t and finish of text introduced or altered by amendment is indicated in the text by tags ! “. 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 wit
27、h EU Directive(s), see informative Annexes ZA and ZB, which are integral parts of this document.“ This standard comprises two parts: Part 1 relates specifically to tail lifts for goods (whether or not accompanied by an operator); Part 2 covers the special requirements of tail lifts for passengers, i
28、ncluding those with disabilities. This document includes a Bibliography. 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, Cyprus, Czech Republic, Denmark, Esto

BS EN 1756-2:2004+A1:2009EN 1756-2:2004+A1:2009 (E) 6Introduction The mach
30、inery concerned and the extent to which hazards are covered are indicated in the scope of this standard. While producing this standard, it was assumed that: only trained persons operate the machine; components without specific requirements are: a) designed in accordance with the usual engineering pr
31、actice and calculation codes, including all failure modes; b) of sound mechanical and electrical construction; c) made of materials, with adequate strength and of suitable quality; d) free of defects; harmful materials, such as asbestos are not used; components are kept in good repair and working or
32、der, so that the required dimensions remain fulfilled despite wear; by design of the load bearing elements, a safe operation of the machine is assured for loading ranging from zero to 100 % of the rated possibilities and during the tests; a mechanical device built according to good practice and the
33、requirements of the standard, will not deteriorate to a point of creating a hazard without the possibility of detection; the equipment is capable of operating correctly within a temperature range of 15 C to + 40 C; a negotiation takes place between the manufacturer of the tail lift and the installer
34、 for the characteristics of the supporting wheeled vehicle (see also clause 6), the fitting of the tail lift on or in the vehicle and between the installer and the user relating to the specific conditions of the use, places of use of the machinery, also some of the characteristics of the vehicle and
35、 the appropriate language; the working area is adequately lit (if lighting is not provided with the tail lift); if the place of installations allows a vertical falling height of persons of more than 3 m notwithstanding the limited travel height indicated in the scope, means external to the machine a
36、re used to limit this falling height to 3 m. !This European Standard is a type C standard as stated in EN ISO 12100.“When the provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisi
37、ons of the other standards, for machines that have been built according to the provisions of this type C standard. BS EN 1756-2:2004+A1:2009EN 1756-2:2004+A1:2009 (E) 71 Scope Part 2 of standard EN 1756 specifies safety requirements for design of tail lifts as defined in 3.1 for mounting on wheeled
38、passenger vehicles. Vehicles for the loading of disabled passengers onto aircraft and ships are included within the scope of the standard (although dock-mounted lifts are excluded). It also specifies the verification of such tail lifts and the safety information that shall be provided for their use.
39、 This document deals with the technical requirements to minimise the hazards listed in clause 4 which can arise during the operation of tail lifts when carried out in accordance with the specifications as intended by the manufacturer or his authorised representative. It applies to passenger tail lif
40、ts: used for the purpose of embarking and/or disembarking passengers to and from such vehicles; intended to be fitted, temporarily or permanently, either inside or on the front, side or rear of the wheeled vehicle; driven either by hand or by electric power; equipped with a platform to support passe
41、ngers who may be pedestrians or riders in wheelchairs and may be accompanied by an attendant. Embarking and/or disembarking operations include the use of a tail lift to lift and/or lower passengers, and if specifically approved by the manufacturer, for use as a link bridge. The standard covers the s
42、ignificant hazards which could occur when a tail lift is used as intended and under the conditions foreseen by the manufacturer. A list of significant hazards is given in clause 4. This document is not applicable to tail lifts which are manufactured before the date of publication of this document by
