Xiaobian is here to introduce the purpose of the lengthening arm excavator:

1：清理河道或鱼塘

1: Clear the river or fish pond

使用挖掘机加长臂经常能使用在清理河道或鱼塘的工作上，河道和鱼塘都是较深的工作场地，因此要挖掘就需要加长臂的挖掘机才能足够。

The lengthening arm of excavator can often be used to clean the river or fish pond. The river and fish pond are deep workplaces, so the excavator with lengthening arm is needed to excavate.

2：地铁开挖

2: Subway excavation

在修建地铁工程时所有的轨道或地基也需要使用挖掘机加长臂才能进行，也是因为需要挖的深度高而且开槽宽，需要加长型的挖掘机加长臂才能顺利的施展。

In the construction of subway projects, all tracks or foundations also need to use excavator lengthening arms to carry out. It is also because the excavation depth is high and the groove is wide, and the lengthened excavator lengthening arms are required to be smoothly deployed.

3：水利水电工程

3: Water conservancy and Hydropower Engineering

在兴修水利水电工程时也是较常会使用挖掘机加长臂的一大工程，可以根据所需要的深度进行挖掘。在水利水电工程中挖掘机加长臂称之为工程中的清淤，可见其挖掘的能力水平非常好清淤泥能力更强。并且在水利工程的使用中还可根据具体的深度进行加长改装臂长。

In the construction of water conservancy and hydropower projects, excavators are often used to lengthen the arm, which can be excavated according to the required depth. In water conservancy and hydropower projects, the lengthening arm of excavator is called the king of dredging in the project. It can be seen that its excavation ability is very good and its dredging ability is stronger. And in the use of water conservancy projects, the arm length can also be extended and modified according to the specific depth.

4：建筑搬运使用

4: Building handling and use

在各大建筑工地为了能快速的进行高层搬运土砂或混凝土，也会需要使用挖掘机加长臂来帮助进行运送。这样不仅能减少人工搬动的负担而且也提高了安性。

In order to quickly carry out high-rise handling of soil, sand or concrete at major construction sites, excavator lengthening arms will also be used to help transport. This can not only reduce the burden of manual moving, but also improve the safety.

一、挖掘机加长臂类型分类

1、 Type classification of excavator lengthening arm

挖掘机加长臂有两段式挖掘机加长臂和三段式挖掘机加长臂，两段式挖掘机加长臂主要适用于土石方基础和深堑挖掘作业，河道清淤；三段式挖掘机加长臂主要适用于高层建筑的拆卸等工程。根据杠杆原理和力学原理，挖掘机加长臂的受力比原来减少，应该尽量不要去重作业的场合施工

The excavator lengthening arm has two-stage excavator lengthening arm and three-stage excavator lengthening arm. The two-stage excavator lengthening arm is mainly applicable to earthwork foundation and deep cutting excavation operations, and river dredging; The lengthening arm of three-stage excavator is mainly applicable to the demolition of high-rise buildings and other projects. According to the lever principle and mechanical principle, the force on the lengthening arm of the excavator is less than the original, so we should try not to carry out construction in heavy operation
