The invention relates to a crane, in particular a mobile truss boom crane, comprising an upper bracket rotatable about a vertical axis of rotation and a suspended ballast connected to the upper bracket by a suspended ballast guide. The suspended ballast guide has a drive for changing the distance of the suspended ballast to the upper bracket axis of rotation. According to the invention, the suspended ballast guide is connected to the upper carriage by means of at least one force transmission device. The force transmission device is arranged to partially mitigate the load of the suspended ballast guide by an unloading force against the gravity of the suspended ballast, thereby introducing a corresponding reaction force into the upper bracket.

    本发明涉及一种起重机,特别是移动式桁架臂起重机,所述起重机包括可绕竖直旋转轴线旋转的上托架和通过悬挂式压载物引导件连接到所述上托架的悬挂式压载物。所述悬挂式压载物引导件具有用于改变所述悬挂式压载物到上托架旋转轴线的距离的驱动器。根据本发明,所述悬挂式压载物引导件通过至少一个力传输装置连接到所述上托架。所述力传输装置设置成,通过抵抗所述悬挂式压载物的重力的卸载力来部分减轻悬挂式压载物引导件的负载,从而将相应的反作用力引入所述上托架。
