GENERAL CHARACTERISTICS

LIVI 900 motoreducers have been created to meet the most modern automation techniques, and have been studied to
motorize counterweighted or hinged horizontally pivoted doors. The peculiarity of our motoreducers are that they are
compact, thanks to their small size, and to the possibility of being applied both laterally and centrally.
The components have been chosen and finished with particular care to give a high quality, reliable product of good
aesthetic quality.
They are provided with a courtesy lamp.
•
The reducer operates in a grease bath.
•
• They are equipped with a levered mechanical release mechanism, which opens the door in the event of a power failure.
The internal-external release kits have handles or tailor-made spanners.
• They are available in 900 and 1400 revolution versions.
We suggest that one LIVI motoreducer should be installed for doors up to 9 sq m and 2 LIVI motoreducers for doors
•
larger than 9 sq m, whether they be insulated or match boarded.
