A mobile patient bed includes a bench that may be moved vertically via a lifting mechanism. Vertical movement may be effected via a first, electric drive mechanism including a drive device that may be operated when connected to an energy supply. As an alternative, vertical movement may be effected via a second drive mechanism that may be actuated by the operator using a foot pedal. The drive device is a drive motor that is coupled to the lifting mechanism via a motor shaft and is coupled to the second drive mechanism via a clutch. The clutch is closed with no connection to the energy supply and is opened with connection established. The motor shaft may be driven via the second drive mechanism when the clutch is closed.
