Abstract

grua. a presente invenção refere-se a uma grua, em particular, a uma grua de torre com uma lança rotacionável em torno de um eixo de mecanismo de rotação vertical e um freio fora de serviço, que permite e retarda o movimento de rotação da lança em uma condição fora de serviço. de acordo com a invenção, o freio fora de serviço é formado para operar em função da velocidade rotacional, de modo que em uma velocidade rotacional mais alta da grua, o torque de frenagem aplicado é maior que em uma velocidade rotacional mais baixa da grua.
