s1UALIFICATIONREQUIRED
฀ •฀Complete฀training฀of฀an฀industrial฀electrical฀technician฀having฀a฀specialisation฀in฀and฀specific฀experience฀
of electrical apparatus of lifting and handling systems.
1. If performed correctly maintenance work guarantees the safety of jib crane operators and reduces downtime
to a minimum after a breakdown.
2. Repairs carried out opportunely prevent further deterioration of the crane and its components.
3. Use original spare parts and products.
4. To prepare the crane for maintenance work the following rules must be followed:
฀ •฀
The staff appointed to do the ordinary or extraordinary maintenance work must have read and understood
well all the instructions contained in this chapter and in chapter 3.
฀ •฀Extraordinary฀maintenance฀work฀must฀only฀be฀carried฀out฀by฀authorised,฀qualified฀staff,฀trained฀for฀the฀
job.

Special recommendations regarding maintenance:
For฀problems฀which฀may฀come฀about฀or฀to฀order฀spare฀parts฀contact฀the฀DONATI฀SOLLEVAMENTI฀
S.r.l. Technical Assistance Service.
Electromechanical technician:
He฀ is฀ a฀ highly฀ specialised฀ and฀ specifically฀ trained฀ operator,฀ whose฀ professional฀ profile฀
combines฀and฀synthesizes฀not฀only฀the฀abilities฀and฀knowledge฀typical฀of฀the฀electrical฀
technician, but also those of the mechanical technician.
Maintenance work must be carried out, when possible, while the crane is not connected to the power
supply฀ and฀ in฀ safe฀ conditions,฀ using฀ suitable฀ tools฀ and฀ adequate฀ personal฀ protection฀ devices,฀ in฀
accordance฀with฀the฀regulations฀in฀force,฀and฀affixing฀a฀sign฀with฀the฀warning:฀“MAINTENANCE฀
