In a crane (1) provided with a control cabin (8) and comprising a mast (2) and an arm (3), said control cabin (8) is movable about the mast (2) to follow the arm (3) at the swinging of the latter. In order to facilitate the co-ordination of the movements of the control cabin (8) and the arm (3), these parts are provided with each their electronic angle transmitter (9, 10) measuring their angular positions in the horizontal plane. The angle transmitters are connected to a computer unit (11) which is capable of controlling the driving of the arm (3) for its swinging and the movements of the control cabin (8) about the mast (2) on the basis of the measure values obtained from the angle transmitters (9, 10). |
