Method, system and computer program product for moving a load by means of a plurality of cranes

System for moving a load by means of a plurality of cranes, comprising at least two cranes, which each comprise an upper structure that is rotatable by means of a slewing gear about a vertical axis of rotation, a jib that can be luffed about a horizontal axis by means of a luffing mechanism, a load receiving means that is vertically adjustable by means of a lifting mechanism and is intended for receiving a load, and a control unit by means of which the upper structure, jib and load receiving means are automatically controllable,

• wherein
• one of the cranes can be defined as a leading crane and the control units are configured to automatically control the cranes not defined as the leading crane (trailing cranes) in such a way that their movements follow the movements of the leading crane, wherein the control units of the cranes are configured to exchange data,
• the control units are configured, upon lifting or lowering of the load, to control and/or to regulate the lifting mechanisms of the trailing cranes such that the heights of the contact points of the load on the respective load receiving means (lifting heights) remain within a defined window around the lifting height of the leading crane,
• the control units are configured to automatically control and/or regulate the luffing and lifting mechanisms of the cranes for a lateral movement of the load such that during a luffing movement of the jib the lifting height remains constant, and
• at least one crane comprises a measuring device (50) for detecting a deviation of the lifting cable, carrying the load receiving means, from the vertical, wherein the control unit of said crane is configured, if a deviation is detected, to control and/or regulate the luffing mechanism and/or the slewing gear such that the deviation is compensated for.
