2、ty of the Standards Policy and Strategy Committee on 7 January 2005 BSI 2006 ISBN 0 580 45306 5 National foreword This Draft for Development is the official English language version of CEN/TS 13001-3-2:2004, including Corrigendum July 2006. When Parts 1, 2, 3.1, 3.2 and 3.3 of this standard are publ
3、ished, BS 2573 Parts 1 and 2 will be withdrawn. This publication is not to be regarded as a British Standard. It is being issued in the Draft for Development series of publications and is of a provisional nature because CEN/TS 13001-3-2:2004 is itself a provisional standard. NOTE A CEN/TS is a “Tech
4、nical Specification” issued by CEN for an evolving technology, with a view to it being developed to full EN status within 3 years. It should be applied on this provisional basis, so that information and experience of its practical application may be obtained. Comments arising from the use of this Dr
5、aft for Development are requested so that UK experience can be reported to the European organization responsible for its conversion to a European Standard. A review of this publication will be initiated 2 years after its publication by the European organization so that a decision can be taken on its
6、 status at the end of its 3-year life. Notification of the start of the review period will be made in an announcement in the appropriate issue of Update Standards. According to the replies received by the end of the review period, the responsible BSI Committee will decide whether to support the conv
7、ersion into a European Standard, to extend the life of the Technical Specification or to withdraw it. Comments should be sent in writing to the Secretary of BSI Subcommittee MHE/3/1, Crane design, at British Standards House, 389 Chiswick High Road, London W4 4AL, giving the document reference and cl
8、ause number and proposing, where possible, an appropriate revision of the text. A list of organizations represented on this subcommittee can be obtained on request to its secretary.

After two years the members of CEN will be requested to submit their comments, particularly on the question whether the CEN/TS can be converted int
13、o a European Standard. CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available promptly at national level in an appropriate form.

28、 5 Introduction This Technical Specification has been prepared to be a harmonized standard to provide one means for the mechanical design and theoretical verification of cranes to conform with the essential health and safety requirements of the Machinery Directive, as amended. This standard also est
29、ablishes 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 Technical Specification is a type C standard as stated in EN ISO 12100-1:2003. The machinery concerned
30、 and the extent to which hazards are covered are indicated in the scope of this standard. 1 Scope This Part 3-2 of the Technical Specification EN 13001 is to be used together with Part 1 and Part 2 and as such they specify general conditions, requirements and methods to prevent mechanical hazards of
31、 wire ropes in reeving systems of cranes by design and theoretical verification. NOTE 1Specific requirements for particular types of crane are given in the appropriate Technical Specification for the particular crane type. The following is a list of significant hazardous situations and hazardous eve
32、nts that could result in risks to persons during normal use and foreseeable misuse. Clauses 5 to 6 of this standard are necessary to reduce or eliminate the risks associated with the following hazard: Exceeding the limits of strength. This Technical Specification is applicable to cranes which are ma
33、nufactured after the date of approval by CEN of this standard and serves as reference base for the Technical Specifications for particular crane types.
