6.5 Troubleshooting
6.5.1 Main causes of malfunctions or faults and possible solutions
The columns of the table below show the main malfunction conditions that can be reasonably predicted
and the type of problem, potential cause of the fault and possible solutions.

excessive inclination of rotation
axis
•
check the verticalness of the crane and
tightening of fixing system
6.5.2 Personnel authorised to intervene in the event of a failure
The personnel authorised to work in most of the cases of fault, or unless otherwise reported, is an expert
maintenance person or one who is authorised based on specific preparation on the mechanical and
electrical parts When highlighted the intervention of specialised or specifically trained personnel or the
manufacturer’s technical personnel is necessary.
6.5.3 Decommissioning
If it is not possible to repair the jib crane, decommission it, indicating the fault with a specific sign; ask for
intervention from the assistance service.
6.6 Disassembly, disposal and scrapping
If the jib crane and its components, because broken, worn or at the end
of their expected life cycle, can no longer be used or repaired, they
need to be demolished.
•
Demolition of the jib crane must be performed using suitable equipment selected in relation to the
material on which to intervene ( e.g. shears, blow torch, hacksaw, etc.)
•
All of the components must be dismantled and scrapped after having reduced them to small pieces so
that none of them can be reasonably reused.
•
When the jib crane is scrapped, its parts must be recycled taking into account their various natures
(metals, oil and lubricants, plastic, rubber, etc.) possibly hiring specialised companies authorised for
this purpose and complying with the laws regarding the disposal of solid industrial waste.
Do not attempt to reuse the parts or components of the jib crane that apparently may
seem still intact once that they, following check and tests and/or replacements
conducted by specialised personnel or the manufacturer, have been declared no longer
suitable.
