<p>The invention concerns a method and equipment for dampening the swing of a crane's load, where the equipment includes an open control system for controlling the movements of the crane's lifting carriage (1), and aimed at minimizing the swing of the load (2). In order that it is also capable of effectively dampening the swing that the open control system is not capable of dampening, the equipment also includes a means of calculating the ideal plan of movements achieved with the help of the open control system, and mechanical swing prevention equipment (3, 4), and equipment for controlling the dampening behaviour of the mechanical swing prevention equipment, so that it allows load swing according to the said ideal plan of movements, and dampens only the swing that deviates from this ideal plan of movements.</p> |
