Abstract: The present invention relates to a method and a device for lifting a load, wherein at least one aerial drone carries at least a portion of the load. In order to lift a load, it is proposed to yoke together a plurality of aerial drones or at least one aerial drone and a lifting hook of a crane, and provide a common control system for the plurality of aerial drones or the at least one aerial drone and the lifting hook of the crane, in order not to have to control a plurality of aerial drones at the same time, or also an aerial drone in addition to the crane hook, using separate control means, in a “multi-handed” manner. In addition to the at least one aerial drone which carries at least a portion of the load, it is proposed, according to the invention, that the load should be connected to a further aerial drone and/or a lifting hook of a crane, and also carried and/or directed by the further aerial drone or the crane lifting hook in part, wherein the two aerial drones are controlled together, and/or the at least one aerial drone is controlled together with the crane, in a mutually coordinated manner, by means of a common controller for controlling flight and/or crane movements.
