Abstract

Electromechanical safety gear device for elevator apparatus, that can be electronically activated for the emergency braking of a car longitudinally movable along a guide (1), the device comprising an engagement block integral with the car. The device comprises an activation plate (2) movable with respect to the guide (1) and operable by the activation mechanism, and a guiding element (4) of a braking element (6), movable by a guiding mechanism (3) in a direction parallel to the guide (1). The activation plate (2) additionally comprises a friction element (12) for defining relative positions of the activation plate (2) with respect to the guide (1): a standby position, with the activation plate (2) spaced from the guide (1), an active position, in which the friction element (12) contacts said guide (1), and a braking position.
