General purpose offshore cranes EN BSI also holds the copyright, in the UK, of the publications of the international standardization bodies.

The Red document status indicator indicates that the document is an old version The document has likely been withdrawn by the publisher, also the meta data presented here may be out of date as it is no longer being maintained by the editorial teams at NBS. Limit states and proof of competence of rope reeving components. These variations, if calculated in conformity with the agreed service conditions, are the base for estimating the histories of load effects e.
All identified stress cycles are classified for statistical presentation. The Amber document status indicator indicates that some caution is needed when using this document – it is either: A list of organizations represented on this subcommittee can be obtained on request to its secretary.
NOTE Specific requirements for particular types of crane are given in the appropriate European Standard for the particular crane type. Service conditions are considered in a general way, independent of the type of crane and the way it is driven. We would be 1001-1 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 130001-1 be found on the inside front cover.
The average linear index lin or angular index ang displacement X is classified in Table 3. When agreed upon Fj shall also be multiplied by an appropriate risk coefficient y n. Subscribing members of BSI are kept up to date with standards developments and receive substantial discounts on the purchase price of standards.
Electrotechnical equipment prEN All supports, where given limits are exceeded, i. For cranes or crane 10301-1 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. Power driven hoists EN EN ISO 1 21 For all crane systems, the limit state method is applicable without any restriction. The average number of accelerations p of the drive under consideration is classified in Table 5 and illustrated in Figure 5.
When 13001–1 1, 2, 3. The average displacement X should be estimated from the average displacements T r for all tasks r and the corresponding relative number of working cycles a r as follows: 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. For this purpose the limit state method, and where 13001-1 the allowable stress method, is used in accordance with international and European design codes.

Moveable cabins EN Load actions Part 3. Individual specified loads f, shall be calculated and amplified ba necessary using the factors fa and shall be combined according to the load combinations under consideration. 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.
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 relative number of working cycles a r for each task r is given by the expression a. Except as permitted under the Copyright, Designs and Patents Act no extract may be reproduced, stored in a retrieval system or transmitted in any form or by any means — electronic, photocopying, recording or otherwise — without prior written permission from Bd. The resulting stress J, shall be compared with the allowable stress adm o.
This publication does not purport to include all the necessary provisions of a contract.
General principles and requirements EN In the following clauses only a is dealt with. In cases where the loads from simultaneous actions of different drives affect each other dependent, non-orthogonalthis shall be taken into account.

Hazards can occur if extreme values of load effects or their histories exceed the corresponding limit states.
There is a distinction between ultimate limit states and serviceability limit states as follows: General principles and requirements AMD Search the history of over billion web pages on the Internet.
