Abstract
A device for controlling two cooperating boom cranes that are used to hoist and move a common load and are pivotable around individual vertical axes and are equipped with booms that can adopt variable elevation angles, with one of said cranes being driven, the crane main, by a main driving device, and the other crane, the auxiliary crane, being driven by an auxiliary drive device; with position indicators installed to explore the correct positions of both cranes in terms of rotation and elevation; whose device is characterized in that signals corresponding to the vectors of the horizontal projections of the gables, to the length of the object that constitutes the load, and to the distance between the cranes, are fed to an adder instrument projected in such a way as to generate a signal of fault or deviation corresponding to any defective positioning of the main crane or of the auxiliary crane or of both, the deflection signal being supplied, after detecting its phase and its direction, to the control devices of the cranes. In addition, the signals of the main drive device are also input to the auxiliary drive device, which comprises a computer which, based on the signals received from the position indicators of the main and auxiliary cranes, calculates an auxiliary control signal which is adjusted approximately to the ordered movement, this signal being introduced, in conjunction with the deflection signal of the auxiliary crane, in another adder instrument projected in such a way as to generate a corrected control signal corresponding to the expected positioning of the auxiliary crane, whose signal is introduced into the auxiliary control device, after detecting its phase and its sense.
