随着我国农村和城镇建设的发展，工程建设不断增加，生活中旧建筑不断被拆除重建。我们对这些现象并不感到惊讶。在施工现场，我们看到的工程设备更多的是挖掘机。在很多情况下，旧建筑的拆除是用挖掘机加长臂和破碎锤来的。那么如何正确使用这种挖掘机加长臂呢？让我们马上看看。

With the development of rural and urban construction in our country, engineering construction is constantly increasing, and old buildings in daily life are constantly being demolished and rebuilt. We are not surprised by these phenomena. At the construction site, we see more engineering equipment as excavators. In many cases, the demolition of old buildings is solved by using excavators with extended arms and crushers. So how to use this excavator to extend the arm correctly? Let's take a look right away.

（1）每次使用时，检查挖掘机加长臂高压或低压油管是否松动；同时，为小心，随时检查其他地方是否漏油，避免振动导致油管脱落，导致故障。

(1) Before each use, first check if the high-pressure or low-pressure oil pipes of the excavator's extended arm are loose; At the same time, to be careful, always check for oil leaks in other areas to avoid vibration causing oil pipes to fall off and cause malfunctions.

（2）破碎特别硬的物体时，应从边缘开始，不要在同一点连续敲击超过1分钟，以防止钎焊杆烧毁或液压油过热。

(2) When crushing particularly hard objects, start from the edge and do not continuously strike at the same point for more than 1 minute to prevent the brazing rod from burning out or the hydraulic oil from overheating.

（3）不要用挖掘机加长臂的护板作为推动重物的工具。因为挖掘装载机主要是小型机器，所以重量轻。如果推重物，会损坏破碎锤，导致主机吊臂断裂，甚主机翻车事故。

(3) Do not use the excavator with extended arm guards as a tool to push heavy objects. Because excavators and loaders are mainly small machines, they are lightweight. If a heavy object is pushed, it will damage the crushing hammer, causing the crane arm of the main engine to break, and even the main engine to overturn.

（4）使用挖掘机加长臂进行破碎作业时，钻杆应始终垂直于破碎物体的表面。并使钻杆压碎物体，破碎后立即停止破碎锤工作，防止空打。持续的无目标冲击会损坏破碎锤的前体和主螺栓松动，严重时会损坏主机本身。

(4) When using an excavator with an extended arm for crushing operations, the drill pipe should always be perpendicular to the surface of the crushed object. And crush the object with the drill pipe, and immediately stop the hammer from working after crushing to prevent empty hitting. Continuous aimless impact can damage the front body and loose main bolts of the crushing hammer, and in severe cases, it can damage the host itself.

（5）破碎时，不要使用摇动钻杆，否则主螺栓和钻杆可能破裂；不要使破碎锤迅速坠落或撞击硬石为过度冲击会损坏挖掘机加长臂。

(5) When breaking, do not use shaking the drill pipe, otherwise the main bolt and drill pipe may break; Do not let the hammer fall quickly or hit hard rocks as excessive impact can damage the excavator's extended arm.

（6）不要在水中或泥泞的地面上破碎。除钻杆外，挖掘机加长臂的其他部分不得浸泡在水中或泥泞中，否则活塞等功能相似的部件会因泥渍堆积而过早损失破碎锤。

(6) Do not break in water or muddy ground. Except for the drill pipe, the other parts of the excavator's extended arm must not be immersed in water or mud, otherwise similar components such as the piston may lose the hammer prematurely due to mud accumulation.
