In combination with the agreed service conditions and the kinematic properties of the crane or its parts, these values limit the histories of inner forces or nominal stresses for the proof of fatigue strength. 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.

Such superimpositions are called load combinations. Stress histories characterised by the same value of s may be assumed to be equivalent in respect to the damage in similar materials, details or components. For the proof based on forces, moments, deflections the limit state method shall be applied by analogy. Static equivalent loads are given in EN If these details are to be used for any other purpose than implementation then the prior written permission of BSI must be obtained.

The proof of competence according to EN shall be carried out by using the general principles and methods appropriate for this purpose and corresponding ne the recognised state of the art in crane design.

Marking 26 Licensed Copy: Hazards can occur if extreme values of load effects or their histories exceed the corresponding limit states. For dated references, subsequent amendments to or revisions of any 4 Licensed Copy: 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.

For this purpose the limit state method, and where applicable the allowable stress method, is used in accordance with international and European design codes. 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.

Information on standards BSI provides a wide range of information on national, European and international standards through its Library and its Technical Help to Exporters Service. Each of the stress cycles is sufficiently described by its upper and lower extreme value from which the value of the stress amplitude and mean stress may be determined as follows: Using the established rules of metal fatigue the large number of variable magnitude stress cycles are condensed to one or two parameters.

Subscribing members of BSI are kept up to date with standards developments and receive substantial discounts on the purchase price of standards. General purpose offshore cranes EN For the proof of rigid body stability it shall be shown that under the combined action of the loads multiplied by their partial safety factors no rigid body movement occurs. In some applications the effect of occasional loads can occur regularly.

Basic load combinations are given in EN Key a working space 1 b working space 2 Figure 4 — Service frequencies n ri and during task r in the working spaces 1 and 2, average linear displacement in the direction of movement of the drive under consideration Working movements within one working space shall be considered as a separate task. Want access to British Standards? For the proof of fatigue strength, occasional and exceptional loads are usually neglected.

We would be grateful if anyone finding an inaccuracy or ambiguity while using this British Standard would inform the Secretary of the technical committee responsible, the identity of which can be found on the inside front cover. For the proof of fatigue strength of components the stress histories acting on them may also be directly specified, considering the service conditions, by selecting a class S according to Table 6.

Once this standard is cited in the Official Journal of the European Communities under that Directive and has been implemented as a national standard in at least one Member State, compliance with the normative clauses of this standard confers, within the limits of the scope of this standard, a presumption of conformity with the relevant Essential Requirements of that Directive and associated EFTA regulations.

Users are responsible for its correct application.

For proof that yielding and elastic instability do not occur, the nominal stress J u due to the action of the load effects on a particular element or component shall be calculated and combined with any stresses Y u resulting from local effects. The other parts are as follows: 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.

For cranes or crane configurations where all the loads from different drives acting simultaneously do not affect each other because they are acting at right angles to each other i. 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.

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.

Supersedes BS EN General principles and requirements EN The range of total numbers of working cycles C is classified in Table 2. Non-electrotechnical equipment EN General Principles and requirements Part 2: For the proof of fatigue strength, loads are multiplied by the dynamic factor in accordance with EN 1 -2, whilst all partial safety factors y P are set to 1. The allowable stress method can also be used for portions of MDC2 systems that act in the same manner as a linear MDC1 system.

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 1300-1 described in the scope.

Figure 1 illustrates the general layout of a proof calculation for cranes.
