6.2 The qualifications of maintenance staff.<br />
§ To be capable to adequately carry out maintenance work of jib cranes maintenance staff must:<br />
• know the laws in force related to accident prevention during work carried out on machines with motor<br />
transmissions and be able to apply them.<br />
• have read and understood chapter 3 “Safety and Accident Prevention”.<br />
• be able to use and consult this document.<br />
• know the functioning of the machine.<br />
• recognise irregularities regarding functioning and when necessary take necessary measures to rectify<br />
them.<br />
§ Professional figures appointed and authorised to carry out maintenance on the crane are:<br />
Operator of the jib crane.<br />
• Typical maintenance activities:<br />
• Verification of proper functioning of the jib crane. Cooperation with staff appointed to periodical<br />
and/or extra maintenance work, after having informed them of any anomalies found in the<br />
functioning.<br />
• Cleaning and lubrication of the parts of the crane (hoist) which the operator is normally in contact<br />
with (push-button panel, hook) and simple maintenance work which does not require intervention<br />
at a height (e.g. lubrication of the thrust bearing of the hook).<br />
• Technical knowledge required:<br />
• knowledge of the functions and use of the jib crane<br />
• knowledge of the lubricants utilised in the crane and in the hoist and of the dangers associated with<br />
their use.<br />
• Qualification required:<br />
• suitability to the work in relation to the specific operative and environmental characteristics.<br />
Mechanical maintenance officer<br />
• Typical maintenance activities:<br />
• mechanical regulation of the clearance of brakes and mechanisms<br />
• test movements and mechanical regulation of the safety devices<br />
• check mechanical clearance and wear of the components (chain, hook, etc.)<br />
• replacement of components which can wear out (chain, hook, chain guide, pulleys) according to<br />
this publication<br />
• ordinary maintenance of mechanical units after substitution of parts with original spare parts<br />
• Technical knowledge required:<br />
• good knowledge of mechanical lifting systems and handling with a manual and motor driven<br />
system<br />
• good knowledge of safety devices used on the hoist (limit switches, brakes, overload switch,<br />
etc.)<br />
• basic knowledge of the moderately difficult techniques for electric checking and adjustment<br />
(limit switch adjustment, replacement of fuses, motor connection, etc.)<br />
• knowledge of the methods of measurement and testing to determine the actual state of the<br />
conditions of the crane and of the hoist (tests of: brakes, chain and hook wear, anomalous<br />
noise, etc.)<br />
• logical trouble-shooting methods of non complex breakdowns and evaluation of the results<br />
• ability to arrange the necessary measures to put the hoist back into working order<br />
• ability to write a maintenance intervention report<br />
• Qualification required:<br />
•• • • Complete<br />
training of an industrial mechanic having a specialisation in and experience of liftingsystem<br />
maintenance or of industrial handling<br />
