1. A safety brake device for a load receiving component of an elevator installation, the safety brake device comprising:
brake equipment, the brake equipment being configured to work with a guide rail for the load receiving component, the brake equipment comprising a cam disc rotatable about a cam disc axis; and an electrically controlled activating mechanism, the activating mechanism being configured to activate the safety brake device by rotating the cam disc through an activation rotational angle such that the cam disc contacts the guide rail, the activating mechanism comprising a pivotably mounted activating lever and an activating spring, the activating spring causing a pivot movement of the activating lever prior to contact of the cam disc with the guide rail, the activating lever being fixed in an initial position in a first operating state of the safety brake device and the activating lever being pivotally driven by the activating spring to an end position when the activating mechanism is released in a second operating state of the safety brake device, the activating lever being coupled with the cam disc such that the pivot movement of the activating lever from the initial position toward the end position rotates the cam disc through the activation rotational angle. |
