This standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”, Directive 98/37/EC, (valid until 28 December 2009) and the “revised Machinery Directive”, Directive 2006/42/EC, which takes effect on 29 December 2009, and which apply to m

7、achines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of the directives. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard

8、 and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The European Standards referred to in clause 2 and in the bibliography of this document have been published as the corresponding DIN EN or DIN EN ISO

32、“ 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, including those with disabilities. This document includes a Bibliography. According to the CEN/CE

EN 1756-2:2004+A1:2009 (E) DIN EN 1756-2:2009-12 5Introduction The machinery concerned and the extent to which hazards are covered are indicated in the scope of this stan

35、dard. 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 practice and calculation codes, including all failure modes; b) of sound mechanical and electrical co

36、nstruction; 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 order, so that the required dimensions remain fulfilled despite wear; by design of the load bearing e

37、lements, 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 requirements of the standard, will not deteriorate to a point of creating a hazard without the poss

38、ibility of detection; the equipment is capable of operating correctly within a temperature range of 15C to + 40C; a negotiation takes place between the manufacturer of the tail lift and the installer for the characteristics of the supporting wheeled vehicle (see also clause 6), the fitting of the ta

39、il 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 the appropriate language; the working area is adequately lit (if lighting is not provided with the t

40、ail 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 are used to limit this falling height to 3 m. !This European Standard is a type C standard as stated i

41、n 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 provisions of the other standards, for machines that have been built according to the provisions of this ty

42、pe C standard. EN 1756-2:2004+A1:2009 (E) DIN EN 1756-2:2009-12 61 Scope Part 2 of standard EN 1756 specifies safety requirements for design of tail lifts as defined in 3.1 for mounting on wheeled passenger vehicles. Vehicles for the loading of disabled passengers onto aircraft and ships are include

43、d 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. This document deals with the technical requirements to minimise the hazards listed in clause 4 which c

44、an 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 lifts: used for the purpose of embarking and/or disembarking passengers to and from such vehicles; intende

45、d 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 passengers who may be pedestrians or riders in wheelchairs and may be accompanied by an attendant. Embarking

46、 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 significant hazards which could occur when a tail lift is used as intended and under the conditions fore

47、seen 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 CEN. 2 Normative references The following referenced documents are indispensable for the application o
