Abstract

See full text

A safety brake device at a load receiving component of an elevator installation includes brake equipment that co-operates with a guide rail of the load receiving component. The brake equipment includes a cam disc that is rotatable about a cam disc axis and for activation of the safety brake device is set into a rotation through an activation rotational angle by an activating mechanism, wherein as a consequence of such rotation the cam disc comes into contact with the guide rail, whereby the guide rail moving relative to the safety brake device when the load receiving component is travelling rotates the cam disc into a position in which the brake equipment and thus the safety brake device produce an intended braking action relative to the guide rail. The activating mechanism includes a pivotally mounted activating lever driven by an activating spring to rotate the cam disc.
