N o Recommendation(s) to: Atlas Cranes UK Ltd<br />
136 Take action to ensure that:<br />
• All Atlas 170.2 cranes supplied in the UK have been installed using<br />
fastenings of the diameter, grade and number of fastenings as<br />
promulgated by Atlas GmbH.<br />
• The M24 nylon insert lock nuts supplied are of the same grade or<br />
higher than their associated studs.<br />
• The operators of all other Atlas crane installations in the UK, for<br />
which Atlas UK has supplied fastenings, are made aware of the<br />
potential that the nuts that have been supplied may be of an<br />
insufficient grade.<br />
Appropriate action planned<br />
