The BS 2573 series will remain current until all parts of the BS EN 13001 series cited above have been pu

BS EN 13001-3-2:2014EN 13001-3-2:2014 (E) 5 Introduction This European Standard has been prepared to be a harmonized standard to provide one means for the mechanical design and theoretical verification of cranes to conform to the essential health and safety requirements of the Machinery Directi

29、ve, as amended. This standard also establishes interfaces between the user (purchaser) and the designer, as well as between the designer and the component manufacturer, in order to form a basis for selecting cranes and components. This European Standard is a type C standard as stated in EN ISO 12100

30、. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this standard. 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 standard take

31、precedence over the provisions of the other standards, for machines. BS EN 13001-3-2:2014EN 13001-3-2:2014 (E) 6 1 Scope This European Standard is to be used together with EN 13001-1 and EN 13001-2 and as such they specify general conditions, requirements and methods to prevent mechanical hazards of

32、 wire ropes of cranes by design and theoretical verification. NOTE Specific requirements for particular types of cranes are given in the appropriate European Standard for the particular crane type. The following is a list of significant hazardous situations and hazardous events that could result in

33、risks to persons during intended use and reasonably foreseeable misuse. Clauses 5 to 6 of this standard are necessary to reduce or eliminate risks associated with the following hazard: exceeding the limits of strength (yield, ultimate, fatigue). This European Standard is not applicable to cranes whi

34、ch are manufactured before the date of its publication as EN and serves as reference base for the European Standards for particular crane types (see Annex C). EN 13001-3-2 deals only with the limit state method in accordance with EN 13001-1. 2 Normative references The following documents, in whole o
