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