<p>ISO 10972-3:2003 establishes requirements which apply specifically to the mechanisms and related components of tower cranes, in addition to the general requirements given in ISO 10972-1.</p>
<p>These additional requirements concern the arrangement, features and characteristics of the crane mechanisms, and the minimum requirements for certain mechanism components.</p>
<p>Rules for the proof of competence calculation regarding different limit states (yield strength, fatigue, wear) are excluded from ISO 10972-3:2003.</p>
<p>ISO 10972-3:2003 is not applicable to the climbing mechanisms and related components used on tower cranes, nor to the climbing frame.</p>
