35、The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are covered are indicated in the scope of this document. When 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 standa

36、rd take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. The object of this European Standard is to define rules for safeguarding persons and objects against the risk of accidents associated wit

37、h the operation of Mobile Elevating Work Platforms (MEWPs). This European Standard does not repeat all the general technical rules applicable to every electrical, mechanical or structural component. The safety requirements of this European Standard have been drawn up on the basis that MEWPs are peri

38、odically maintained according to manufacturers instructions, working conditions, frequency of use and national regulations. It is also assumed that MEWPs are checked for function daily before start of work and are not put into operation unless all required control and safety devices are available an

39、d in working order. If a MEWP is seldom used, the checks may be made before start of work. Furthermore it is assumed that persons on the work platform in case of power supply failure are not incapacitated and can assist in the emergency lowering. As far as possible this European Standard sets out on

40、ly the requirements that materials and equipment need to meet in the interest of safety, and it is assumed that persons operating MEWPs are adequately trained. Where for clarity an example of a safety measure is given in the text, this does not need to be considered as the only possible solution. An

41、y other solution leading to the same risk reduction is permissible if an equivalent level of safety is achieved. As no satisfactory explanation could be found for the dynamic factors used for stability calculations in previous national standards, the results of the tests carried out by the former CE

42、N/TC 98/WG 1 to determine a suitable factor and stability calculation method for MEWPs have been adopted. The test method is described in Annex B (informative) as a guide for manufacturers wishing to use higher or lower operating speeds and to take advantage of developments in control systems. Simil

43、arly, to avoid the unexplained inconsistencies in coefficients of utilisation for wire ropes found in other standards for lifting devices, appropriate extracts of the widely accepted standard DIN 15020-1 have been taken into 5.5.2 and Annex C (normative) with a worked example in Annex D (informative

45、 sizes of Mobile Elevating Work Platform (MEWP, see 3.1) intended to move persons to working positions where they are carrying out work from the work platform (WP) with the intention that persons are getting on and off the work platform only at access positions at ground level or on the chassis. NOT

46、E Machines designed for the handling of goods which are equipped with work platforms as interchangeable equipment are regarded as MEWPs. 1.2 This European Standard is applicable to the structural design calculations and stability criteria, construction, safety examinations and tests before MEWPs are

47、 first put into service. It identifies the hazards arising from the use of MEWPs and describes methods for the elimination or reduction of these hazards. It does not cover the hazards arising from: a) use in potentially explosive atmospheres; b) electromagnetic incompatibility; c) work from the plat

48、form on external live electric systems; d) use of compressed gases for load bearing components; e) getting on and off the work platform at changing levels; f) specific applications (e.g. railway, ships) covered by National or local regulations. 1.3 This European Standard does not apply to: a) machinery serving fixed landings (see e.g. EN 81-1 and EN 81-2, EN 12159); b) fire-fighting and fire rescue appliances (see e.g. EN 1777); c) unguided work cages suspended from lifting appliances (see e.g. EN 1808); d) elevating operator position on rail dependent storage and retrieval equipment (
