Magnitude, position and direction of all loads which act simultaneously in the sense of a load combination, shall be chosen in such a way that extreme load effects occur in the component or design detail under consideration. A flow chart illustrating the limit state method for the proof calculation based on stresses is shown in Figure 2. Various BSI electronic information services are also available which give details on all its products and services.
Non-electrotechnical equipment EN This vs not preclude the free use, in the course of implementing the standard, of necessary details such as symbols, and size, type or grade designations. C is the total number of working cycles during the useful life of the crane; C r is the number of working cycles of task r. For the proof of fatigue strength, occasional and exceptional loads are usually neglected.
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. 10301-1 Specific requirements for particular types of crane are given in the appropriate European Standard for the particular crane type.
The allowable stress method can also be used for portions of MDC2 systems that act in the same manner as a linear MDC1 system.

BSI offers members an individual updating service called PLUS which ensures that subscribers automatically receive the latest editions of standards. Alternatively, advanced and recognised theoretical or experimental methods 130001-1 be used in general, provided that they conform to the principles of this standard.

Compliance with a British Standard does not of itself confer immunity from legal obligations. This publication does not purport to include all the necessary provisions of a contract.
The relationship between stress amplitudes to failure by fatigue and mean stress or stress ratio for the component under consideration for fatigue assessment is shown in Figure 7. The above given two-parameter presentation of stress histories is shown 13001-1 Figure 6. 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.

Hazards can occur if extreme values of load effects or their histories exceed the corresponding limit states. The range of total numbers of working cycles C is classified in Table 2.

Specification for classification, stress calculations and design criteria for structures Ne but remains current. All identified stress cycles are classified for statistical presentation.
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.

The limit state method see 4. It presents the UK view on standards in Europe and at the international level.
If a different level of safety is required in some instance, a risk factor y n may be agreed upon and applied. The total number of such operations during the useful life shall be specified.
The stress history is a numerical presentation of all stress variations that are significant for fatigue.
