摘要： A demolition tool for attachment to the boom structure (11) and hydraulic system of a hydraulic excavator having a pair of jaws (22,24) pivotally connected together as to be mountable on the frame of the tool by a movable pin (24) so that the jaws may be placed with other jaws having other forms of demolition characteristics. The jaws may be a shear for steel or other structural material, including concrete, and the jaws may be a concrete crusher, a rock or coral breaker, a wood shear, a plate shear, or other form of demolition device. Both jaws are swingable and independently swingable, operated by a common manifold supplying hydraulic fluid to the cylinders. The jaws swing through operational arcs and are arranged so that the direction of thrust from the cylinders is tangential to the pin connecting the cylinders to the jaws at a location intermediate the ends of the operational arcs.
摘要翻译： 一种用于连接到液压挖掘机的动臂结构（11）和液压系统的拆卸工具，该液压挖掘机具有一对可枢转地连接在一起的夹爪（22,24），以便通过可动销（24）安装在工具的框架上，因此 钳口可以放置在具有其他形式的拆除特征的其他钳口上。 夹爪可以是用于钢或其他结构材料（包括混凝土）的剪切，并且夹爪可以是混凝土破碎机，岩石或珊瑚破碎机，木材剪切机，板剪切机或其它形式的拆除装置。 两个颚板是可摆动的并且可独立摆动，由向液压缸供应液压流体的公共歧管操作。 夹爪摆动通过操作弧，并且布置成使得来自气缸的推力的方向与在圆弧端部处于操作弧的中间位置处将气缸连接到钳口的销相切。
