Free to use BIM project management tool provides step-by-step help to define, manage and validate responsibility for information development and delivery at each stage of the asset life cycle in level 2 BIM projects. References The titles of the standards publications 22573-2 to in this standard are listed on the inside back cover.

In addition to the preparation and promulgation of standards, BSI offers specialist services including the provision of information through the BSI Library and Standardline Database; Technical Help to Exporters; and other services. In assessing the individual loadings arising under case 1 and case 2 loading conditions, the hook load impact factor bx not applied.

In some cases, economic considerations or technical limitations dictate that a component should be designed or selected for a shorter life than the remainder of the mechanism, so that renewal of the component will be necessary during the life of the mechanism: Attention shall be given to the method of mounting and the bolting requirements for which the bbs recommendations shall be taken into account.

As a typical example for guidance, appendix E shows a proposed basis for the derating of hooks in accordance with BS which has regard to their design factor of safety for class 1 crane duty when used on heavy industrial applications. In addition, the requirements for stiffness lateral and torsionalfatigue, influence of bearings, fits of components, etc.

Where other steels are used, the crane manufacturer shall show that the properties are b with the standard steels and that they have been subjected to equivalent tests. Anti-friction bearings shall be installed and fitted in accordance with the manufacturer’s procedures, including adequate provision for their lubrication.

Z p where F 0 is the minimum required breaking load in kN ; S’ is the maximum rope tension in kN as defined in 8. Because crane mechanisms are mounted on structures that are flexible to a greater or lesser extent, particular care is needed in selecting bearings of an appropriate type for each application.

Classes of utilization of mechanisms Class of utilization Service life hours Remarks T1 Irregular use. In determining the loading used as the basis for design under each of 22573-2 loading conditions given in 5. Regeln fuer den Kranbau. Coefficient, c 2for rail wheels Group classification of mechanism C 2 M3 1.

Working stresses 4 9. The use of BS requires a determination of the operating hours per day for a particular crane motion. An approach, based on ISO work, was finally adopted which enables each mechanism of a crane to be classified in respect of the duty it performs, independently of the design classification of the whole crane.

The permissible stress, P cis obtained from table 4 according to the type of stress and case of loading under consideration. The Red document status indicator indicates that the document is an old version The document has likely been withdrawn by the publisher, also the meta data presented here may be out of date as it is no longer being maintained by the editorial teams at NBS. Specifies classification of mechanisms for all types of cranes based on severity of intended use, loads and load combinations, calculation of stresses, stresses in components and the selection and verification bx proprietary items.

You may experience issues viewing this site in Internet Explorer 9, 22573-2 or Derating of hooks table 1 of BS These approaches are implicit in the loading conditions given in clause 5.

The qualities 2573- metal refer to cast, forged or rolled steels and spheroidal graphite cast iron.

Vi Loads due to the service wind acting horizontally in any direction, where applicable. For purpose-built cranes, the selection of an appropriate nominal state of loading for each mechanism may be agreed between the purchaser and manufacturer. BS Document Year It is important that users of British Standards should ascertain that they are in possession of the latest amendments or editions.

Failure of mechanism components represents a hazard of varying importance and can lead to consequential bw and cost which may be considerable. Stresses shall not, however, exceed those specified in clause 7. Case 4 Exceptional loading conditions appropriate to the type of crane and its application that occur infrequently during its life e.
