ABSTRACT:
Devices for changing the slope of rows of tiers, whose bearing structures are definitively or temporarily fast, by a single elevating operation. The devices include tiers whose bearing supports are constituted by first long columns and second short columns, which, by actuation of elevating motors are alternately brought in supporting position of the tiers, the first long columns in active supporting position generating a first, more accentuated slope profile for the tiers, the second short columns, brought in active position of the tiers generating a second less accentuated slope profile.
