<p>The present invention relates to a patient lifter with an electrically driven lifting unit, a lifting hook connected to the electrically driven lifting unit, a controller, a power supply and an operation device. The electrically driven lifting unit, the power supply and the operation device are connected to the controller. The electrically driven lifting unit can be activated by means of the operation device by which the lifting hook can be raised or lowered. The patient lifter comprises a load sensor for determining the size of the load attached to the lifting hook. The load sensor is connected to the controller, which contains a threshold value for the maximum allowed size of the load attached to the lifting hook. Furthermore, the controller is configured to prevent the electrically driven lifting unit from raising the lifting hook, if the size of the load attached to the lifting hook exceeds the threshold value for the maximum allowed size of the load attached to the patient lifter via the lifting hook.</p> |
