Abstract

métodos para reduzir cargas dinâmicas de guindastes. a presente invenção refere-se a um método para reduzir vibrações ressonantes e cargas dinâmicas de guindastes (1), cujos movimentos vertical e horizontal da carga útil (38) são controlados por um guincho de lança (24) controlando o movimento de elevação de uma lança pivotante (16) e um guincho de elevação (360 controlando a distância vertical entre uma ponta da lança (30) e a carga (38) e em que o método inclui as etepas de: - determinar as frequências de ressonância do sistema de lança de guindaste (16) e carga (38) acoplado, tanto experimentalmente ou teoricamente pelo menos a partir dos dados sobre inércia da lança (16) e rigidez de pelo menos um cabo de lança (18), um cabo de elevação (26), um suporte (6) e uma armação-a (19); - geração automática de movimento de amortecimento em pelo menos um dos ditos guinchos (24, 36), que neutraliza as oscilações dinâmicas no guindaste (1); e - adicionar este movimento de amortecimento ao movimento determinado pelo operador de guindaste.
