(57) The present finding concerns a safety device for automatically checking the weight
present on one or more lifting groups of an elevator, of a platform, of a lift or
of other similar apparatuses. Such a device is of the type in which the mobile platform
or the cabin (1), able to slide on the column (2), consists of a board (3) on which
the load rests and a motorisation group (4), formed from a welded structure (5), which
supports the motor group, consisting of a geared motor (6) or another work device,
which takes care of moving the aforementioned platform on the aforementioned column.
Such a safety device is characterised in that it foresees that the two components
of the platform (1), i.e. the board (3) on which the load is rested and the motorisation
group (4) consist of two distinct and separate work groups, between which an intermediate
element (8) is inserted that, as well as acting as connection means between the aforementioned
groups, to allow the entire platform to be moved vertically, also detects the weight
value of the material loaded onto the board.
