Excavator is a kind of mechanical equipment used in engineering construction that we have more opportunities to see in weekdays. For excavator lengthening arm, how to carry out construction when it is used to demolish buildings? And do you have a more in-depth understanding of its scope of application? The following long arm excavator rental will be introduced to 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。

　　Using super long boom and super long bucket stick, the extended boom excavator can play a great role in dredging, revetment, 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 also everywhere. Therefore, the market demand for long arm excavators is very large. For this reason, the excavator arm made by our company will occupy a unique position in this vibrant market segment.

　　一、挖掘机加长臂的使用范围

　　1、 Application range 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。

　　There are two-stage excavator extension arm and three-stage excavator extension arm. The two-stage excavator extension arm is mainly used for earthwork foundation and deep cutting excavation, and river dredging; the three-stage excavator extension arm is mainly used for demolition of high-rise buildings. According to the lever principle and mechanics principle, the force of the lengthening arm of the excavator is less than the original one, so the construction should not be carried out in heavy operation.

　　挖掘机加长臂如何运用到拆楼之中？

　　How to use the extended arm of excavator to demolish buildings?

　　二、三段式挖掘机加长臂如何拆楼？

　　2、 How to demolish the building with the extended arm of three section excavator?

　　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, demolishing a five storey building:

　　1、必须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. Some mud or industrial waste must be transported to the bottom to make the excavator lift straight and the impact hammer can reach the roof.

　　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 filling material, make it stable 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 1 meter away from the top), open a hole in the wall, and push the broken material inside. 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. Don't move the beams and columns. Open the brick wall and hit the column, so that the beam above can not support it will also fall inside, to ensure their own safety. In this order, from top to bottom, push in.
