长臂挖掘机

省时 省力 省财富

In recent years, the use frequency of excavator lengthening arm is relatively high, especially in demolition and other aspects. But we need to consider several problems before installing and using the lengthening arm. First of all, what kind of excavator has the ability to install the extension arm, and the use range of the lengthening arm, and so on.

一、什么样的挖掘机可改装成加长臂挖掘机

1、 What kind of excavator can be modified into an extended arm excavator

新机不建议改装，因为改装成加长臂挖掘机以后，挖掘机负荷增大，况且没过保修期容易与原厂产生售后服务的纠纷；五成新以下的机也不建议改装，因为机器使用年限比较旧，各方面性能减退，加上加长臂本身也有一定重量，很难发挥出加长臂挖掘机应有的效率，更好的是5-8成新的挖掘机改装成加长臂挖掘机。

It is not recommended to refit the new machine, because the load of the excavator increases after refitting to an extended arm excavator. Moreover, it is easy to have after-sales service disputes with the original manufacturer before the warranty period. For machines below 50% new, modification is not recommended because the service life of the machine is relatively old, the performance of all aspects is reduced, and the lengthening arm itself has a certain weight, so it is difficult to give full play to the efficiency of the excavator The best is that 50-80% of new excavators are converted into extended arm excavators.

二、挖掘机加长臂的使用范围

2、 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，加长臂挖掘机的受力比原来减少，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 extended arm excavator is less than that of the original one, so the construction should not be carried out in heavy operation.

三、三段式挖掘机加长臂如何拆楼？

3、 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 filler, 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，保证自己的安全。按这样的顺序从上到下，往里推进。

4. Enlarge the hole and do not 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.

四、怎样选择挖掘机加长臂生产厂家

4、 How to choose the manufacturer of excavator lengthening arm

由于原装挖掘机加长臂的价格太高，很多老板不能承受，所以副厂生产的挖掘机加长臂成了大多数挖掘机老板的，目前国内生产挖掘机加长臂的厂家鱼龙混杂，有的小厂连工程师也没有，就几个焊工，所采用的材料也是便宜的不达标的钢材，其质量售后可想而知，所以建议各位挖掘机老板在选择挖掘机加长臂厂家的时候一定要慎重，不要为了贪图一时的便宜而给您造成不必要的损失，建议选择时亲自去厂考察。目前国内信誉质量比较厂家集中在东莞，因为东莞是全球制造业基地，各方面配套比较完善，企业也比较重视质量。

Because the price of the original excavator boom is too high, many owners can not afford it. Therefore, the excavator boom produced by the auxiliary factory has become the first choice of most excavator owners. At present, domestic manufacturers of excavator lengthening arm are mixed. Some small factories do not even have engineers. Only a few welders use cheap and substandard steel. The quality of the after-sales service can be imagined I know, so it is suggested that the excavator owners should be careful when choosing the manufacturer of excavator and long arm. Do not cause unnecessary loss to you for the sake of temporary cheap. It is suggested that you go to the factory for inspection when choosing. At present, domestic reputation and quality comparison manufacturers are concentrated in Dongguan, because Dongguan is a global manufacturing base, supporting facilities in all aspects are relatively perfect, and enterprises also pay more attention to quality.
