An electromechanical monitoring device for detecting undesired departure of an elevator cage from standstill includes a co-running wheel which when required is pressed against a guide track of the elevator cage, possibly against a running diameter of the speed limiter. A sensor detects rotation of the co-running wheel and actuates a braking device if a rotational angle of the co-running wheel exceeds a predetermined value. This electromechanical monitoring device can be suitable for attachment to or installation in a speed limiter and can be suitable for retrofitting to elevator installations.
