Excavator is a kind of mechanical equipment used in engineering construction that we have a lot of opportunities to see on weekdays. For the excavator extension arm, how to carry out construction when it is used for demolition? And do you have a deeper understanding of its scope of application? The following editor will introduce you.

华体会国际 利用超长型动臂和超长型斗杆，可在疏浚、护岸、坡面以及地铁建设等受地面环境限制的工况下发挥巨大的威力。当前全国各地纷纷上马地铁建设，为保护环境而进行的河道疏浚治污等工程也是遍地开花，因此华体会国际 的市场需求很大。为此我公司制做的挖掘机加长臂，将在这个生机勃勃的细分市场占据自己独特的一席之地。

The extended boom excavator uses an ultra long boom and an ultra long bucket rod, which can exert great power under the conditions restricted by the ground environment such as dredging, bank protection, slope and subway construction. At present, subway construction has been launched all over the country, and river dredging and pollution control projects for environmental protection are blooming everywhere. Therefore, there is a great market demand for extended arm excavators. For this reason, the excavator extension arm made by our company will occupy its own unique position in this dynamic market segment.

一、挖掘机加长臂的使用范围

1、 Application scope 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 boom includes two-stage excavator lengthening boom and three-stage excavator lengthening boom. The two-stage excavator lengthening boom is mainly applicable to earthwork foundation and deep cutting excavation and river dredging; The extended arm of three-stage excavator is mainly applicable to the demolition of high-rise buildings and other projects. According to the lever principle and the mechanical principle, the force of the excavator's lengthening arm is less than the original, and the construction should not be carried out in heavy work.

二、三段式挖掘机加长臂如何拆楼？

2、 How to demolish a building with three-stage excavator and extended arm?

主要还是看楼房高低而定，举个例子，拆5层楼房：

It mainly depends on the height of the building. For example, the demolition of a five storey building:

1、先运来一些泥或工业垃圾垫底，使挖掘机升直冲击锤可以够得到楼顶。

1. First, transport some mud or industrial waste to the bottom, so that the excavator can reach the roof with the impact hammer.

2、待挖掘机开上填充物后先使其稳定，并且留有足够的转向空间。

2. After the excavator opens the filler, stabilize it and leave enough steering space.

3、用冲击锤垂直墙面向里打墙(距顶1米左右)，把墙打开一个洞，碎料往里推，不要让它掉下来砸到自己。

3. Use the impact hammer to hit the wall vertically (about 1m away from the top), open a hole in the wall, and push the broken material inward. Don't let it fall and hit yourself.

4、把洞扩大，先不要动梁和柱子。把砖墙打开后就打柱子，这样上面的梁支持不住也会往里面掉，保证自己的。按这样的顺序从上到下，往里推进。

4. Expand the hole without moving the beams and columns. After opening the brick wall, hit the column, so that the beam on the top will fall inside even if it is not supported, so as to ensure your own safety. Push in from top to bottom in this order.
