Limit states and proof of competence of rope reeving components. The relative number of working cycles a r for each task r is given by the expression a. Limit states and proof of competence of machinery.

Clause 4 of this standard is necessary to reduce or eliminate the risks associated with the following hazards: Use of an intermediate value for a parameter is permissible, but in that case this design value shall be determined and marked instead of the class.

The allowable stress method is a special case of the limit state method, where the partial safety factors are given the same value, which combined with the resistance coefficient, forms an overall safety factor y f. For the proof of fatigue strength, occasional and exceptional loads are usually neglected. Search the history of over billion web pages on the Internet. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Central Secretariat or to any CEN member.

Supersedes BS EN Service conditions are considered in a general way, independent of e type of crane and the way it is driven. The fatigue assessment of the combined effect of such histories – interaction – is based on the action of the independent ones. Figure 5 — Example for class P 4. Where details concerning the numbers of working cycles and the masses of the particular net loads to be handled are not known, an appropriate relative frequency shall be agreed between the user, manufacturer and designer for each task r.

A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the Central Secretariat has the same status as the official versions. 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 e components. Static equivalent loads are given in EN If a different level of safety is required in some instance, a risk factor y n may be agreed upon and applied.

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.

Non-electrotechnical equipment EN The load spectrum factor kQ r for each task r is determined from kQr where: The following is a list of significant e situations hs hazardous events that could result in risks to persons during normal use and foreseeable misuse.

The range of total numbers of working cycles C is classified in Table 2. The upper and lower extreme values of the load effectsin terms of inner forces or nominal stresses, shall be used for a static proof calculation to avoid the hazards described in the scope. A flow chart illustrating the limit state method for the proof calculation based on stresses is shown in Figure 2.

In some applications the effect of occasional loads can occur regularly. Electrotechnical equipment prEN The analysis of load actions from individual events or representative use of a crane representative load histories is required to reflect realistic unfavourable operational conditions and sequences of actions of the crane. For details of these and other benefits contact Membership Administration.

When establishing the load combinations, consideration shall be given to the use of the crane, taking into account its control systems, its normative instructions for use, and any hs inherent conditions, where they relate to the specific aim of 113001-1 proof of competence.

It presents the UK view on standards in Europe and at the international level. Click here to find out how to access this document. General Principles and requirements Part 2: 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.

Such superimpositions are called load combinations. For the proof of fatigue strength, the number and magnitude of significant stress cycles shall be specified. When agreed upon Fj shall also be multiplied by an appropriate risk coefficient y n. For this purpose the limit state method, and where applicable the allowable stress method, is used in accordance with international and European design eb.
