    • The present invention is a self-contained hydraulic hammer which is mounted on a hydraulically mobile frame. The hydraulic hammer is capable of travelling in either forward or reverse directions and is provided with liftable weights to which a tool for digging or breaking up a surface is attached. The hydraulic hammer is equipped with time delay controls which: 1) momentarily stop the travel of the hydraulic hammer as the weights and the attached digging tool free fall from a raised position until the digging tool impacts the surface to be busted up, and 2) cause the hydraulic hammer to resume travel as the weights are again raised in preparation for another impact. The hydraulic hammer rapidly repeats these cycles of impact and travel to break up a surface. Adjustments are provided on the hydraulic hammer for regulating the force of the impact and the distance travelled between impacts in order to match the hydraulic hammer's impact and travel cycles to the break characteristics of the surface to be removed.
    • 本发明是一种独立的液压锤,其安装在液压移动框架上。 液压锤能够在正向或反向方向上行进,并且设置有可拆卸的重物,附接有用于挖掘或破碎表面的工具。 液压锤具有时间延迟控制功能:1)当重物和附加挖掘工具从升高的位置自由落下,直到挖掘工具撞击表面被打破时,液压锤立刻停止行驶; 2) 导致液压锤继续行进,因为重量再次升高以备另一冲击。 液压锤快速重复这些冲击和行进循环以破坏表面。 在液压锤上提供调节以调节冲击力和撞击之间的距离,以将液压锤的冲击和行程循环与要移除的表面的断裂特性相匹配。
