Abstract
The invention relates to a lifting device with a housing having a drive wheel, a friction disk brake, a load wheel and a gear arranged sequentially in an axial direction inside the housing. The drive shaft extends through the friction disk brake and the load wheel. A torque is transmitted from the drive wheel to the load wheel. The drive wheel cannot move axially on the drive shaft, but can rotate over a limited range relative to the drive shaft. The drive wheel can rotate in a limited fashion relative to a brake disk, which is axially moveable on a threaded section of the drive shaft and can be pressed with the help of a friction disk against a pressure disk that is attached to the housing. The drive wheel forms a component of the friction disk brake.
