with the incorrect size of tie bolts<br />

The locknuts supplied were of a<br />

lower grade than indicated by their<br />

markings<br />

testing of the crane failed to<br />

identify a number of deficiencies<br />

The manufacturer or distributor<br />

did not supply any installation<br />

guidance<br />

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 />
