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.

A steel wire self-locking mechanism and a lifting device are provided. The steel wire self-locking mechanism includes a surrounding plate and a self-locking gear and a locking device arranged in the surrounding plate, and uses a friction force of a threaded sleeve to lock the lifting device. The lifting device includes a lifting assembly and a beam assembly. The steel wire self-locking mechanism is arranged in the beam assembly, and the locking of the lifting device is realized by the steel wire self-locking mechanism. The steel wire self-locking mechanism and the lifting device have good adaptability. Due to a smaller volume, the steel wire self-locking mechanism is applicable to lifting tables in various sizes.
