The invention relates to a cantilever crane vibration suppression device, an elevating fire truck and a cantilever crane vibration suppression method. The cantilever crane vibration suppression method comprises a first method, the first method comprises the steps that at least two sub-control signals needing to be input to a proportional valve are determined according to the to-be-executed action of a cantilever crane (10), and the proportional valve is used for controlling the action of the cantilever crane (10); and the at least two sub-control signals are sequentially overlapped and input to the proportional valve at intervals of preset time, and the sub-control signal input later is configured to reduce vibration caused by the sub-control signal input earlier. According to the method, a time-sharing control signal input method is adopted, vibration caused by the earlier input sub-control signal to the cantilever crane is reduced through the later input sub-control signal, and vibration of the cantilever crane is effectively restrained.

    本发明涉及一种臂架抑振装置、举高消防车和臂架抑振方法,其中臂架抑振方法包括第一方法,所述第一方法包括:根据臂架(10)的待执行动作确定需要输入给比例阀的至少两个子控制信号,所述比例阀用于控制臂架(10)的动作;将所述至少两个子控制信号间隔预设时间依次叠加输入给所述比例阀,且在后输入的子控制信号被配置为消减在前输入的子控制信号引起的振动。本发明采用分时输入控制信号的方法,通过在后输入的子控制信号消减在前输入的子控制信号使臂架引起的振动,有效抑制臂架发生振动。
