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.

The invention relates to a free fall winch comprising a drum, which can be rotationally driven by a winch drive, wherein a free fall brake is provided for braking the drum in free fall operation. According to the invention, a torque acting on the free fall winch, which depends on the free fall braking torque, is detected by means of a detection device, and a brake actuation force with which the free fall brake is actuated is controlled or adjusted by a control device according to the detected torque.

An overload brake and method for trolley suspended on a flange of a load traveling apparatus girder prevents the displacement movement of a suspended load along a girder by clamping a brake between two symmetrical flange tabs of the girder. The girder is elastically deformed by the load which is applied to the girder by the contact between a surface of the girder and translation wheels that move the load along the girder. Upon sufficient elastic deformation, portions of the girder contact a brake to prevent movement of the load along the girder.

A safety brake for a load lifting gear includes an actuator for a locking pawl, a brake-locking gear element connected to a lifting gear drive, pawl position monitoring sensors and a controller. The controller monitors the sensors and the lifting gear speed, and operates the lifting gear drive and the actuator to brake the lifting gear against excessive speed, by moving the actuator between energized and non-energized states and differentiating with sensor inputs among a detached state, a bearing state and a fully engaged state of the locking pawl with a pawl clearance of the brake-locking gear element.
