Abstract (en)
[origin: EP4043379A1] Electromechanical parachute activation system for elevating devices, comprising an activation plate (2), a braking element (3), a trigger (5) adapted to cooperate with an electromagnet (8) and with the activation plate (2) through a protruding element (4) thereof, a first spring (6), a cam (7) attached to one end of the trigger (5) and provided with actuation means (9), wherein the trigger (5), the first spring (6), the cam (7) and the means (9) cooperate so that when the electromagnet (8) is activated, the trigger blocks the movement of the protruding element (4) separating the plate (2) from the guide, when the electromagnet is not activated and there is no movement of the elevating device, the first spring (6) exerts a force such that the trigger (5) pivots on the protruding element (4) but does not release it and when there is a movement of the car, the cam (7) pivots on the guide so that the trigger (5) releases the protruding element (4). In this way, the system can be kept in stand-by without any consumption and it is possible to reset the system simply by powering the electromagnet again.
