In many cases it is desirable that separate components forming part of a mechanism e. R 2 Loads due to the dead weight of those parts of the crane acting on the mechanism or component under consideration. British Standards are revised, when necessary, by the issue either of amendments or of bz editions.
Anti-friction bearings shall be installed and fitted in accordance with the manufacturer’s procedures, including adequate provision for their lubrication. Please download Chrome or Firefox or view our browser tips. 253-2
Case 3 Crane out of service. Case 4 Exceptional loading conditions appropriate to the type of crane and its application that occur infrequently during its life 273-2. Table T 2 gs the hours per day to be used for design purposes for each class of utilization when designing gearing in accordance with BS Amendment dated September Large changes in section shall be avoided wherever possible.

Similar effects may occur during braking or collision. Standard Number BS When the class of utilization and the state of loading has been determined, the group classification of a mechanism shall be determined from table 3.
General principles and requirements. Mechanism duty factor, G 5 5. The plug-in limits the number of times the document may be printed to two copies. For any component, the magnitude of the fatigue reference stress depends upon: Einteilung, Spannungsberechnungen und Konstruktion von Ausruestungsteilen.
Design and selection shall have regard to the potentially serious consequences of failure. Where bolts are tightened by controlled means to comply with the requirements of clause 13 of Part 1: This shall be obtained by taking account of the following factors: In some sb, 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: Part 2 ; Foreword The preparation of a British Standard dealing with design stress levels in the mechanisms of cranes was begun in response to demand from the user industries and particularly the public sector.
Surface finish factor, C 3 19 8.
It is an important responsibility of the designer and manufacturer to ensure that torque values are correctly and appropriately quantified so that mechanism will perform as required in the service environment for the intended life.
U s is the ultimate tensile strength of the material.
Derating of hooks 20 4. The gearing shall 2573-22 designed for a service life compatible with the service life of the mechanism of which the gearing forms a part.
Treatment of multiple stress concen- trations in bz proximity is outside of the scope of this appendix and where this situation arises reference should be made to established reference works. The following loadings shall be taken be account when designing a mechanism and its components. Jewellery Road vehicles engineering Railway engineering Shipbuilding and marine structures Aircraft and space vehicle engineering Materials handling equipment Packaging and distribution of goods Textile and leather technology Clothing industry Agriculture Food technology Chemical technology Mining and minerals Petroleum and related technologies Metallurgy Wood technology Glass and ceramics industries Rubber and plastic industries Paper technology Paint and colour industries Construction materials and building Civil engineering Military affairs.
257-32 cranes lift and transport heavy loads, there is a major safety aspect in their design which has, to some extent, to be related to the level of design stresses permitted.
The qualities of metal refer to cast, forged or rolled steels and spheroidal graphite cast iron. No part of this publication may be reproduced in any form without the prior permission in writing of BSI.
