o assembly and handling tests.
These operations must be carried out by qualified staff prior to every time the equipment
us used. Any irregularity must be reported and work stopped.
10.1 Periodical control
The equipment and accessories must be regularly tested by expert staff, at least once
every three months. For the structure and the accessories provided (pins, brackets, etc.),
a special register must be used (example shown in Annex N° I). This register must be
kept up to date, writing the result of the control and must be signed by the person
carrying out the actual control.
In the event of any “irregularity” occurring, use of the device must be stopped, to enable
an accurate examination to be carried out by expert technicians.
Various types of “irregularities” can occur. This following is just a list to facilitate their
possible identification; it must also be noted that these defects could also occur
simultaneously. The main ones are:
o oxidation and/or corrosion – widespread or limited to an element;
o fatigue cracks or localized deformations;
o buckling/deformation of the structure or elements (for example the ovaling of the
pins’ and pinions’ holes, bending of the brackets, etc.);
o wear (for example of the pins, pinions or contact zones);
o damage of the protective surface treatment, probable sign of an underlying crack;
o deterioration of the safety indications (red area on the rear brackets);
o etc.
The register must always be at the disposal of the authorities responsible for controls.
In particular, the following checks must be carried out for the rigging accessory:
o overall structure and, in particular, the elements’ welding;
o ovalization, deformation and/or cracks in the pinion holes;
o conditions of the fixing pins and pinions.
11 REMOVING FROM USE
In the event of even just one of the following list of defects being found in any component
of the array, it must be immediately removed from use:
o cracks in any element of the structure;
o permanent deformations of the load-bearing structures;
o non-compliant results of the checks carried out.
12 DISPOSAL AND SCRAPPING
If any component has to be scrapped for any reason, the disposal must be carried out by
authorized companies, and in compliance with the current regulations regarding this
matter.
