The responsible German body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Technical Committee NA 060-22-26 AA Hebebhnen of Section Frdertechnik und Logistiksysteme. Represen
5、tatives of manufacturers and users of lifting equipment and of the employers liability insurance associations contributed to this standard. This standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”, Directive 98/37/EC (valid until 28 Dec
6、ember 2009), and the “revised Machinery Directive”, Directive 2006/42/EC, which takes effect on 29 December 2009, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requireme
7、nts of the directives. 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 requirements of the Machinery Directive (“presumption of conformity”). The European St
8、andards referred to in this document have been published as the corresponding DIN EN or DIN EN ISO Standards with the same number. This standard makes reference to documents which were valid as of the publication of the European standard. Since then, the standards EN 811 and EN 954-1 have been withd
9、rawn and replaced. Instead of EN 811 it is recommended to make reference to DIN EN ISO 13857, Safety of machinery Safety distances to prevent hazard zones being reached by upper and lower limbs and instead of EN 954-1 to make reference to DIN EN ISO 13849-1, Safety of machinery Safety-related parts
10、of control systems Part 1: General principles for design. Amendments This standard differs from DIN EN 1494:2001-04 as follows: a) The standard has been revised and brought in line with the new EU Machinery Directive 2006/42/EC. b) Annex ZB (informative) “Relationship between this European Standard
11、and the Essential Requirements of EU Directive 2006/42/EC” has been added.

This European Standard shall be given the status of a national standard, either by publicat
27、ion of an identical text or by endorsement, at the latest by June 2009, and conflicting national standards shall be withdrawn at the latest by December 2009. This document includes Amendment 1, approved by CEN on 2008-11-09. This document supersedes EN 1494:2000. The start and finish of text introdu
28、ced or altered by amendment is indicated in the text by tags ! “. This European Standard 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),

31、uction !This European Standard is a type C standard as stated in EN ISO 12100-1:2003.“ This standard has been prepared to be a harmonised standard to provide one means of conforming with the essential Safety Requirements of the Machinery Directive and associated EFTA Regulations. The object of this
32、European Standard is to define rules for safeguarding persons against the risk of accidents associated with the operation of mobile or movable jacks. The extent to which hazards are covered is indicated in the scope of this standard. In addition, machinery should comply as appropriate with !EN ISO 1
33、2100“ for hazards which are not covered by this standard. While producing this standard it was assumed that only trained persons operate the lifting equipment; the working area is adequately light; harmful materials such as asbestos are not used; components are kept in good repair and working order;
34、 by design of the load bearing elements a safe operation of the machine is assured for loads up to 100 % of the rated load and during the tests under the conditions given by the manufacturer; a negotiation for special uses took place between the user and the manufacturer; components without specific
35、 requirements are a) designed in accordance with the usual engineering practice and calculation methods, including all failure modes; b) of sound mechanical and electrical construction; c) made of materials with adequate strength and of suitable quality. 1 Scope This European Standard specifies tech
36、nical safety requirements and measures for mobile or movable jacks (see 3.6) and associated lifting equipment. This European Standard deals with all significant hazards pertinent to mobile or movable jacks and associated lifting equipment when they are used as intended and under the conditions fores
37、een by the manufacturer. This European Standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards. This standard applies to lifting equipment (see 3.1) which are mobile or movable and designed to operate under the load, whether operated si
38、ngulary or in multiples to partially or totally raise and lower loads or vehicles at one or more lifting points (excluding the lifting of persons) where working under the raised load is not permitted unless additional means of securing the load in position are in place. DIN EN 1494:2009-05 EN 1494:2
39、000+A1:2008 (E) 6 NOTE Associated lifting equipment means lifting equipment which is similar to those defined in 3.1, but which does not fully comply with these definitions. This standard does not establish additional requirements for power drive by an internal combustion machine; stability of the m
40、obile or movable jacks and associated lifting equipment; operation in severe conditions (e.g. extreme climates, freezer application, strong magnetic fields); operation subject to special rules (e.g. potentially explosive atmospheres, mines); supply by electrical networks where the tolerances in volt
41、age, frequency etc. differ from those in the public supplies; static electric problems; handling of loads, the nature of which could lead to dangerous situations (e.g. molten metal, acids, radiating materials, especially brittle loads); hazards occurring during producing and decommissioning; hazards
42、 occurring when using the lifting equipment on public roads; wind pressure in and out of use; direct contact with foodstuffs; operation on sea ships. This standard applies e.g. to the following lifting equipment mechanical jacks with or without claw; hydraulic jacks with or without claw and with or
43、without integrated pump, e. g. hydraulic trolley jacks, hydraulic transmission jacks, hydraulic pit jacks; pneumatic jacks. This standard does not apply to a) jacks or stabilizers which are permanently fixed to a trailer or a container to support a trailer or container without the tractor-unit; b) h
44、ydraulic cylinders which are permanently fixed to the vehicle for tipping and/or tilting parts of it; c) support stands with the possibility for changing the lift height only without the load; d) hydraulic lifting equipment working with a maximum pressure exceeding 500 bar and where pump and cylinde
45、r are not integrated parts of the same equipment; e) jacks that are delivered with road vehicles for helping when a break-down occurs (including delivery of original spare parts).
