Crane with a structure, with at least one actuator that engages on the structure and a the actuator for the suppression of vibrations of the structure driving control

摘要

Crane (40) with a structure which an arm (2), a counterweight (3) for the boom (2) and between the counterweight (3) and the boom (2) tensioned anchoring elements (7) with at least one actuator that engages on the structure (15 to 18) and a the at least one actuator for the suppression of vibrations of the structure driving control system (13), characterized in that with the at least one actuator (15 to 18), the voltages of a plurality of the anchoring elements (7) are adjustable independently of the structure with respect to their natural frequencies to be detuned and the vibrations of the structure to suppress.
