For the proof of fatigue strength, occasional and exceptional loads are usually neglected. When Parts ns, 2, 3. Revisions British Standards are updated by amendment or revision.

BS EN 13001-1:2015

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: Clause 4 of this standard is necessary to reduce or eliminate the risks associated with the following hazards: 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.

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. The limit state method see 4. A list of organizations represented on this subcommittee can be obtained on request to its secretary. 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.

sb Information on standards BSI provides a wide range of information on national, European e international standards through its Library and its Technical Help to Exporters Service. The load spectrum factor kQ r for each task r is determined from kQr where: The result y n -Fj shall be used to determine the resulting load effects S ki. A nominal stress is a stress calculated in accordance with simple elastic strength of materials theory, excluding local stress concentration effects.

bss A flow chart illustrating the allowable stress method is shown in Figure 3. 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. Limit states and proof of competence fn machinery.

The allowable stress method is a special case of the limit state method, where the partial safety factors are 13010-1 the same value, which combined with the resistance coefficient, forms an overall safety factor y f.

130001-1 5 — Example for class P 4. Allgemeine Conception generale – Partie 1: 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.

For the proof based on forces, moments, deflections the limit state method shall be applied by analogy.

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. 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. 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.

The resulting design stress o, shall be compared with the limit design stress lim o. For undated references the latest edition of the publication referred to applies including amendments. 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.

The Amber document status indicator indicates that some 130011-1 is needed when using this document – it is either: The combined load Fshall be used to determine the resulting load effects Sk, i. 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.

The allowable stress method can also be used for portions of MDC2 systems that act in the same manner as a linear MDC1 system. Table 4 shows the classes Q of load spectrum factors kQ.
