挖掘机伸缩臂改装是适用于该挖掘机的工作装置，挖掘机伸缩臂分为外部和内部伸缩臂。挖掘机外部伸缩臂也称为挖掘机滑移臂，是适用于该挖掘机的一种工作装置，外部伸缩臂通过伸缩缸由固定体和移动体延伸和收缩，伸缩行程长度在4米以内。
The modification of excavator telescopic arm is a working device suitable for the excavator. The excavator telescopic arm is divided into external and internal telescopic arms. The external telescopic arm of the excavator, also known as the sliding arm of the excavator, is a working device suitable for the excavator. The external telescopic arm extends and contracts from the fixed body and the moving body through the telescopic cylinder, and the telescopic stroke length is within 4m.
挖掘机内的伸展臂也称为挖掘机桶臂，行程拉伸可达10多米或20多米。可以更好地调整开挖半径、开挖深度、合理的调整装载高度。
The extension arm in the excavator, also known as the bucket arm of the excavator, can stretch more than 10 meters or more than 20 meters. It can better adjust the excavation radius, excavation depth and reasonable loading height.
挖掘机伸缩臂改装不是为了好看，而是为了追求比汽车改造更实用的价值。汽车改造主要是车主认为他的爱车缺乏个性，所以选择了改造。伸缩臂改造认为机器主挖土机手臂不能满足日常工作的要求，因此这两个改造的方向很明确，究竟能考虑哪方面的实际要求呢?挖掘机伸缩臂改造的好处都在这里。
The modification of excavator telescopic arm is not to look good, but to pursue more practical value than automobile transformation. Car transformation is mainly because the owner thinks his car lacks personality, so he chose transformation. The telescopic boom reconstruction considers that the main excavator arm of the machine can not meet the requirements of daily work, so the direction of these two reconstruction is very clear. What practical requirements can be considered? The benefits of excavator telescopic boom reconstruction are here.

挖掘机伸缩臂改造了工作半径小的问题。以往的挖掘机标准臂仅仅是伸缩臂改装后的二分之一或者三分之一甚更少。其次挖掘机深挖工作能力、强有力的伸缩臂改造的驱动装置，满足日常深挖工作。
Firstly, the problem of small working radius is solved in the reconstruction of excavator telescopic boom. In the past, the standard arm of excavator was only one-half or one-third or less of the modified telescopic arm. Secondly, solve the deep excavation capacity of the excavator and the driving device of powerful telescopic arm transformation to meet the daily deep excavation work.
然后，挖掘量方面有了很大提高。以往的挖掘机标准臂膀只能匹配标准的挖斗，现在进行了伸缩臂改造后，可以与更大的挖斗匹配。再是因为前置设备的更换更方便。挖掘机伸缩臂改造的一个重要优点是挖掘机机器主随时将前装置的更换适应不同的环境要求。
Then, the excavation volume has been greatly improved. In the past, the standard arm of the excavator can only match the standard bucket. Now, after the transformation of the telescopic arm, it can match the larger bucket. Moreover, the replacement of front-end equipment is more convenient. An important advantage of the excavator telescopic boom reconstruction is that the excavator machine owner will replace the front device at any time to adapt to different environmental requirements.
除了提高挖掘机伸缩臂工作的要求外，对减少挖掘机的实际燃料消耗，减少挖掘机伸缩臂改造的维修次数也有很大帮助。因为伸缩臂改造采用了更新技术，并考虑了更多的燃料消耗和暴力测试方面。因此，选择伸缩臂改造不是选择简单的手臂更换服务，而是为了更好地适应时代潮流，适应各种工作环境，减轻主体的忧虑。
In addition to improving the working requirements of the excavator telescopic boom, it is also very helpful to reduce the actual fuel consumption of the excavator and reduce the maintenance times of the reconstruction of the excavator telescopic boom. Because the telescopic boom modification adopts newer technology and considers more fuel consumption and violence testing. Therefore, the choice of telescopic arm transformation is not to choose a simple arm replacement service, but to better adapt to the trend of the times, adapt to various working environments and reduce the main body's concerns.
