6.5 Breakdowns and solutions<br />
6.5.1 Main types of failure or breakdowns and possible solutions<br />
§ In the columns of the table that follows the main conditions of bad functioning are shown, which can be<br />
reasonably foreseen and the type of problem, the potential cause of the breakdown and possible<br />
solutions.<br />
Type of failure<br />
Rotation is blocked<br />
Difficult rotation<br />
Instability of the positioning<br />
of the arm<br />
Possible causes of breakdown<br />
• a foreign body has entered the<br />
rotation<br />
• seizure of the bearings<br />
• scant lubrication of the bearings<br />
• excessive leaning of the rotation<br />
axis<br />
6.5.2 Authorised staff for intervention in case of breakdown<br />
56<br />
Possible solution<br />
• remove the foreign body<br />
• replace the bearings<br />
• lubricate<br />
• check the verticality of the crane and the<br />
clamping of the fixing system<br />
The staff authorised to intervene in most cases of breakdown, or where not indicated differently, are<br />
expert maintenance people or trained with a specific preparation on mechanical and electrical parts.<br />
Where shown, however, the intervention of specialised suitably-trained staff or the technical staff of the<br />
manufacturer is necessary<br />
6.5.3 Putting out of service<br />
§ If the jib crane cannot be repaired, proceed to the putting out of service operations, signalling the<br />
breakdown with a sign; request the intervention of the assistance service.<br />
6.6 Dismantling, disposal and scrapping<br />
If the jib crane or its components, whether broken, worn out or at the<br />
end of their designated life, should no longer be usable nor<br />
repairable their demolition must be carried out.<br />
•The demolitiion of the jib crane must be carried out using suitable equipment chosen according to the<br />
nature of the material on which to intervene (e.g.: shears, oxyhydrogen flame,saw, etc...)<br />
•All the components must be dismantled and scrapped having been reduced to small pieces so that none<br />
of them can reasonably be used again.<br />
•When the jib crane is scrapped their parts must be disposed of taking into account the different nature of<br />
them (metals, oils and lubricants, plastic, rubber, etc.) using possibly specialised companies and in any<br />
case according to what the relevant law requires regarding solid industrial waste.<br />
Do not try to use again parts or components of the jib crane which look intact but, after<br />
checks and/or replacements carried out by specialised staff, or by the manufacturer<br />
itself, have been declared no longer fit for use
