    Abstract: The invention relates to a safety brake device (38a-38k) at the load receiving means (2; 2a; 2b) of a lift installation (100; 100a; 100b), comprising brake equipment (300; 300a) which co-operates with a guide rail (7b-7e) of the load receiving means (2; 2a; 2b). The brake equipment (300; 300a) includes a cam disc (55; 55a), which is rotatable about a cam disc axis and which for activation of the safety brake device (38a-38d) is set into a rotation through an activation rotational angle, wherein the cam disc (55; 55a) is so designed that the cam disc as a consequence of rotation through the activation rotational angle comes into contact with the guide rail (7b-7e), whereby the guide rail (7b-7e) moving relative to the safety brake device (38a-38d) when the load receiving means (2; 2a; 2b) is travelling rotates the cam disc (55; 55a) into a position in which the brake equipment (300; 300a) and thus the safety brake device produce an intended braking action relative to the guide rail (7b-7e). The safety brake device (38a-38d) comprises an electrically controlled activating mechanism (45; 45a) with a pivotably mounted activating lever (47; 47a) and an activating spring (52) which when required causes, by way of the activating lever (47; 47a), rotation of the cam disc (55; 55a) through the activation rotational angle.

    Abstract: 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.
