3.2 General safety regulations<br />
§ Before putting the jib crane into service it is necessary:<br />
• to read the technical documentation carefully;<br />
• to find out about the functioning and the positioning of the emergency stopping devices;<br />
• to know which safety devices are installed on the jib crane and where they are positioned;<br />
§ Some activities to be carried out on functioning components (e.g. replacing a hoist chain) expose the<br />
operators to situations of grave danger, so it is necessary to adhere strictly to the following rules:<br />
• Staff must be authorised and properly trained regarding the operating procedures to follow, the<br />
dangerous situations that could occur and the correct methods for preventing them.<br />
• If ,exceptionally, staff have to disactivate completely or partially, open or remove the protective<br />
covers to allow a particular specialised technical intervention of maintenance, inspection or repair to<br />
be carried out, it will be their precise duty to put back immediately the relevant protective covers at the<br />
end of the intervention. The staff in charge must make sure that at the end of the intervention<br />
mechanical parts, tools or other devices used are not forgotten on the crane, since this may provoke<br />
damages or malfunctions.<br />
• Staff in charge of maintenance, inspection and repair operations must use all the necessary and<br />
possible preventive safety measures before beginning work for their own safety, and in particular, they<br />
must check that:<br />
• The jib crane is disactivated and the appropriate preventive measures have been taken (signs,<br />
blocking controls etc.) to avoid the accidental starting. To allow the execution of a technical<br />
intervention on an electric device, in the presence of voltage current, pay the maximum attention and<br />
operate with extreme caution..<br />
3.3 Safety symbols<br />
§ In the manual and in danger zones, signs and pictograms are used to underline or bring attention to<br />
potentially dangerous situations due to residual risks, or to actions which must be performed obligatorily<br />
according to the safety procedures shown in this manual.<br />
