4.3.2 Preparing the place of installation
To allow the installation of the jib crane, the following operations must be
carried out:
• Check that the declaration of suitability/adequacy of the support/fixing structures is present;
• Check that obvious defects of the support/fixing structures are absent (fig.14);
• Check the suitability of the manoeuvre spaces (rotation) available for the jib crane, especially if it
operates in areas where there are other cranes or other manufacturing machines (fig.15);
• Check the suitability and correct functioning of the electric system (fig.16)
1) correspondence of the power line voltage with the voltage for the motors
2) that there is a suitable switch/disconnecting switch for the power line;
3) adequacy of the section of the cable of the electrical power supply;
4) that there is a suitable earthing system;
• Prepare the masses for the test runs equal to: nominal lifting capacity x 1,1
• Prepare the masses for the static test runs equal to: nominal lifting capacity x 1,25
• Prepare the equipment for the slinging and lifting of the masses for the load test runs
• Check that there are the relevant signs to warn of the risks posed by the manoeuvring of the crane.
