ABSTRACT:
The invention relates to a device for securing against the impermissible unreeling speed of a belt element (80) from a shaft (82) of a lifter (70) used for transporting a handicapped person; the shaft is connected to a first gear wheel (84), in order to assure by a structurally simple arrangement that if the belt element (80) has an impermissible unreeling speed, locking of the shaft (82) occurs as a function of the speed of revolution of the shaft (82) receiving the belt element (80), a locking element (102) is moved in between the first gear wheel (84) and a gear wheel (92), as a result of which the first gear wheel (84) is blocked.
