A list of organizations represented on this committee can be obtained on request to its secretary. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October , and conflicting national standards shall be withdrawn at the latest by October Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.
The major changes in this revision are in 4. Annex B has been added. This European Standard is one part of EN For the relationship with other European Standards for cranes, see Annex A. BS EN EN E 4 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 Directive, as amended.
This standard also establishes interfaces between the user purchaser of the crane and the designer, as well as between the designer and the component manufacturer, in order to form a basis for selecting cranes and components. The crane parts, components or machinery concerned and the extent to which hazards 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 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.
BS EN EN E 5 1 Scope This European Standard specifies general principles and requirements to be used together with EN and the EN series of standards, and as such they specify conditions and requirements on design to prevent mechanical hazards of cranes, and a method of verification of those requirements.
NOTE Specific requirements for particular types of crane 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 risks to persons during normal use and foreseeable misuse.
Clause 4 of this European Standard is necessary to reduce or eliminate the risks associated with the following hazards: a instability of the crane or its parts tilting ; b exceeding the limits of strength yield, ultimate, fatigue ; c elastic instability of the crane or its parts buckling, bulging ; d exceeding temperature limits of material or components; e exceeding the deformation limits.
This European Standard is applicable to cranes which are manufactured after the date of approval by CEN of this standard and serves as reference base for the European Standards for particular crane types. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document including any amendments applies. In addition, the machine shall be designed according to the principles of EN ISO for hazards relevant but not significant which are not dealt with by the above mentioned standards.
The proof of competence according to the EN series shall be carried out by using the general principles and methods appropriate for this purpose and corresponding with the recognized state of the art in crane design. Alternatively, advanced and recognized theoretical or experimental methods may be used in general, provided that they conform to the principles of this standard. Hazards can occur if extreme values of load effects or their histories exceed the corresponding limit states.
To prevent these hazards with a margin of safety, it shall be shown that the calculated extreme values of load effects from all loads acting simultaneously on a crane and multiplied with an adequate partial safety coefficient, as well as the estimated histories of load effects, do not exceed their corresponding limit states at any critical point of the crane.

Kanos The stress histories from these occasional loads may be estimated in the same way as those from the regular ones and shall be taken into account for the fatigue assessment. Alternatively, advanced and recognised theoretical or experimental methods may be used in general, provided that they conform to the principles e this standard. It is incorporated by Royal Charter.
