With the construction of cities, the construction of high-rise buildings and metro stations is booming, and the excavation of deep foundation is also increasing. The general traditional construction method is to drive excavators and trucks to the bottom of the pit and pull them out with trucks after the excavator has excavated the soil. But we also have some special conditions which make the construction difficult. For example, the soil is not suitable for cars to enter the pit or repair the pit under the road. It costs too much. As we all know, the traditional extended arm excavator is not suitable for loading, and the longer the excavator is, the more inconvenient it is, the better the clamshell grab telescopic arm excavator can solve this problem.

　　一、适用于狭小空间

　　I. Suitable for narrow space

　　蚌壳抓斗伸缩臂挖掘机不是什么新鲜的工具，早已应用了几十年，但一般不用于普通的开挖。现在蚌壳抓斗配合伸缩臂斗杆安装在挖掘机上，就充分发挥了双方的优点。伸缩臂可以将铲斗伸到30米左右的深度进行开挖，而提起来又不占什么空间，方便装车。

　　Mussel shell grab telescopic arm excavator is not a new tool, has been used for decades, but generally not for ordinary excavation. Now clamshell grab and telescopic arm bucket rod are installed on excavator, which gives full play to the advantages of both sides. The telescopic arm can extend the bucket to a depth of about 30 meters for excavation, but it does not occupy much space to facilitate loading.

　　二、垂直开挖

　　II. Vertical Excavation

　　近年来，蚌壳抓斗伸缩臂挖掘机在国外逐渐得到了越来越多的应用，因为它能有效兼顾挖掘深度和效率，同时应用场合也有所拓展，特别是那些普通挖掘机或加长臂施展不开的场合。

　　In recent years, mussel shell grab telescopic arm excavator has been gradually applied in more and more foreign countries, because it can effectively take into account the depth and efficiency of excavation, while the application occasions have also been expanded, especially in those occasions where ordinary excavators or elongated arms can not be deployed.

　　三、驾驶室向前伸出，便于观察

　　3. The cab extends forward for easy observation.

　　现在有些挖掘机厂商还针对这种应用将驾驶室做成可向前伸出的，方便驾驶员观察，大大提高了效率，像地铁站竖井也可以用这种方式进行开挖了。

　　Now some excavator manufacturers also make the cab protruding forward for this application, which is convenient for drivers to observe and greatly improves efficiency, such as the subway station shaft can also be excavated in this way.

　　四、占地面积小

　　4. Small area

　　蚌壳抓斗伸缩臂挖掘机拥有比华体会国际 更大的挖掘机深度，铲斗也更大，因此效率远高于后者。同时需要的摆动空间更少，适合紧凑的位置，也不需要道路。当然，这种工具也不是随便一台挖掘机就可以安装的，通常只用于20吨以上的挖掘机。

　　The clamshell grab telescopic arm excavator has a deeper excavator depth and a larger bucket than the elongated arm excavator, so its efficiency is much higher than the latter. At the same time, it needs less swing space, suitable for compact location and no road. Of course, this kind of tool can not be installed by any excavator, usually only for excavators of more than 20 tons.

　　五、近距离装车，方便很多，效率也高

　　5. Close loading makes it much more convenient and efficient.

　　在实际运用中，根据情况不同，常常基坑里也会有其他挖掘机，配合蚌壳抓斗，以达到更高的施工效率。

　　In practice, according to different situations, there are often other excavators in the foundation pit, cooperating with clamshell grab, in order to achieve higher construction efficiency.

　　不得不说，蚌壳抓斗伸缩臂挖掘机对于传统的挖掘机还是有不少好处的，它不但使用方便而且还能够大大的提高施工效率，在未来蚌壳抓斗伸缩臂挖掘机将会在我们城市建设中有着更广泛的应用，希望可以对大家有所帮助。

　　It has to be said that the clamshell grab telescopic arm excavator has many advantages for the traditional excavator. It is not only convenient to use, but also can greatly improve the construction efficiency. In the future, the clamshell grab telescopic arm excavator will have a wider application in our city construction, hoping to help you.
