摘要：A method and a safety brake for a lifting device, wherein a solenoid or anotherelectromechanical actuator is used to actuate a pawl, where the position of the pawl ismonitored 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 viaa safety-oriented controller and at least one sensor, where the solenoid or the pawl isarranged such that, via spring force and/or gravity, the pawl is brought into engagementwhen the actuator, for example, the solenoid, is deenergized such that it is possible toexactly define and monitor the limit speed and, by using the two sensors, it is alsopossible to monitor the function and the motion of the pawl and to detect undesiredoperating states.
