(ask Italvibras sales office). Lamellar for
clamped centric weigh have an ample
possibility of adjustment: the particular
adjustment system adopted allows to

group of upper weights with respect to
the group of lower weights and to have
ample adjustment of the centrifugal force
within the same group of weights.
Weight covers
Not envisioned in the MVB-E and MVB-E-
FLC series.
Painting
Electrostatic surface treatment based on
polymerised epoxy polyester powder in
oven at 200°C. Tested in salt spray for 500
