The system comprises a synchronization shaft rotatably supported on an elevator car frame, the synchronization shaft being operatively connected to at least one safety gear, a lever attached to the synchronization shaft, an electromagnet operatively connected to the lever, spring means operatively connected to the synchronization shaft, and resetting means operatively connected to the synchronization shaft. Deactivation of the electromagnet releases the lever allowing the spring means to rotate the synchronization shaft from a first position to a second position in which the safety gear is activated. Activation of the resetting means rotates the synchronization shaft from the second position to the first position in which the safety gear is deactivated and the spring means is brought back to the excited state at the same time.
