There is a distinction between ultimate limit states and serviceability limit states as follows: Limit states and proof of competence of machinery 3 Licensed Copy: A flow chart illustrating the limit state method for the proof calculation based on stresses is shown in Figure 2.

A task r can be characterised by a specific combination of crane configuration and sequence of intended movements.

The total number of working cycles of a crane during its useful life can be separated into the numbers of working cycles corresponding to several typical tasks. Using the established rules of metal fatigue the large number of variable magnitude stress cycles are condensed to one or two parameters.

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 other inherent conditions, where they relate to the specific aim of the proof of competence.

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. Moveable cabins EN The average number of accelerations p of the drive under consideration is classified in Table 5 and illustrated in Figure 5.

The stress history is a numerical presentation of all stress variations that are significant for fatigue.

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. Basic load combinations are given in EN Service conditions ba considered in a general way, independent of the type of crane and the way it is driven.

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 113001-1 situations and hazardous events that could result in risks to persons during normal use and foreseeable misuse. These static equivalent loads are considered as deterministic actions, which have been adjusted in such a way that they represent load actions during the use of the crane from the actions or circumstances under consideration.
