Technical Specification• Scope of the supply• Delivery schedule• Documentation• Site activities

January 14th-15th 2014


Scope of the Supply• Following our planning, about 25 cranes are

foreseen to be subject to intervention in the next 5 years

• Dismantling, refurbishment or replacement of obsolete EOT cranes as well as the supply, installation and commissioning of new ones

• Five years blanket purchase contract• Definition of a catalogue of prices (IT-

3981_EN UPL)



Scope of the Supply

Catalogue of prices is structured as follows:

• Basic prices for interventions on cranes (A2 – F11)

• Prices for additional features (G1 – G18_F)• Price for different contexts of installation (H1

– H4)
