2、2016. It supersedes DD CEN/TS 13001-3-5:2010 which is withdrawn.Proof load testing of hooks, as practised for decades in the UK, is uncommon in many other countries of the European Union. This standard treats proof load testing of hooks as an optional procedure and therefore represents a fundamental
3、 departure from current UK practice. BS 2903 and BS 3017 (the now obsolete British Standards for forged steel hooks) required each hook to be proof load tested prior to its entry to service. This provided irrefutable proof of the hooks integrity and its capacity to carry intended service loads. Resi
4、dual stress fields set up in the regions of maximum stress as a result of this proof load test provide an additional benefit in that fatigue performance is significantly improved.Whilst general requirements for a proof load test can be found in Annex K, the UK committee is concerned that neither the
5、 proof load test as practised in the UK, nor its beneficial effect on the fatigue performance of proof load tested hooks, have been addressed adequately in this standard. Further information on proof load testing as practised in the UK for the hook forms shown in Table A.3 can be found in BS 2903:19

BS EN 13001-3-5:2016EN 13001-3-5:2016 (E) 5 Introduction This European Standard has been prepared to provide a mean
37、s for the mechanical design and theoretical verification of cranes to conform to essential health and safety requirements. This European Standard also establishes interfaces between the user (purchaser) and the designer, as well as between the designer and the component manufacturer, in order to for
38、m a basis for selecting cranes and components. This European Standard is a type C standard as stated in EN ISO 12100. 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 stand
39、ard 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. BS EN 13001-3-5:2016EN 13001-3-5:2016 (E) 6 1 Scope This European Standard is to be used together with EN 13001-1 a
40、nd EN 13001-2 and, as such, they specify general conditions, requirements and methods to prevent by design and theoretical verification, mechanical hazards in crane hooks. This European Standard covers the following parts of hooks and types of hooks: bodies of any type of hooks made of steel forging
41、s; machined shanks of hooks with a thread/nut suspension. Principles of this European Standard can be applied to machined shanks of hooks in general. However, stress concentration factors relevant to designs not given in this standard would have to be determined and applied. NOTE 1 Cast hooks and pl
42、ate hooks, which are those, assembled of one or several parallel parts of rolled steel plates, are not covered in this European Standard. The following is a list of significant hazardous situations and hazardous events that could result in risks to persons during normal use and foreseeable misuse. C
43、lauses 4 to 8 of this document are necessary to reduce or eliminate the risks associated with the following hazards: a) exceeding the limits of strength (yield, ultimate, fatigue); b) exceeding temperature limits of material. The requirements of this European Standard are stated in the main body of
44、the document and are applicable to forged hook designs in general. The commonly used hook body and shank designs listed in Annexes A, B and F are only examples and should not be referred to as requirements of this European Standard. Annex I gives guidance for the selection of a hook size, where a ho
45、ok body is in accordance with Annex A or B. The selection of hook form is not limited to those shown in Annexes A and B. This European Standard is applicable to cranes, which are manufactured after the date of approval of this European Standard by CEN, and serves as a reference base for product stan
46、dards of particular crane types. NOTE 2 This part of EN 13001 deals only with the limit state method in accordance with EN 130011. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
