A method and a safety brake for a lifting device, wherein a solenoid or another electromechanical actuator is used to actuate a pawl, where the position of the pawl is monitored via at least two switches or sensors, where the lowering motion of the load or the lifting device is monitored and the safety brake is triggered in the event of a fault via a safety-oriented controller and at least one sensor, where the solenoid or the pawl is arranged such that, via spring force and/or gravity, the pawl is brought into engagement when the actuator, for example, the solenoid, is deenergized such that it is possible to exactly define and monitor the limit speed and, by using the two sensors, it is also possible to monitor the function and the motion of the pawl and to detect undesired operating states.
