长臂挖掘机

省时 省力 省财富

The telescopic arm of excavator is easy to see at the construction site. What kind of excavator can be modified to extend the telescopic arm?

首先，新机不建议改装。挖掘机增加伸缩臂后，挖掘机的负荷增加，保修期后容易与原厂发生售后纠纷。

First of all, it is not recommended to refit the new aircraft. After the telescopic boom is added to the excavator, the load of the excavator increases, and it is easy to have after-sales disputes with the original manufacturer after the warranty period.

其次，五成新以下的机器不建议改装。因为其机器的功能已经比较老了，另外，由于伸缩臂本身有一定的重量，难以发挥伸缩臂挖掘机的优势。

Secondly, it is not recommended to refit the machines below 50% new. Because the function of the machine is relatively old. In addition, because the telescopic boom itself has a certain weight, it is difficult to give full play to the advantages of the telescopic boom excavator.

所以，我们建议五到八成新的挖掘机安装伸缩臂。

Therefore, we suggest that 50 to 80% of new excavators install telescopic boom.

挖掘机伸缩臂包括两级挖掘机伸缩臂和三级挖掘机伸缩臂，两级挖掘机伸缩臂主要适用于土方基础和深裂缝开挖工作和河道疏浚，三级挖掘机伸缩臂主要适用于高层建筑施工及拆除其他工程。根据杠杆原理和力学原理，加长臂挖掘机的动力比原来的要小，所以在施工时要避免繁重的工作。

The excavator telescopic boom includes two-stage excavator telescopic boom and three-stage excavator telescopic boom. The two-stage excavator telescopic boom is mainly suitable for earthwork foundation, deep crack excavation and river dredging. The three-stage excavator telescopic boom is mainly suitable for high-rise building construction and demolition and other works. According to the lever principle and mechanical principle, the power of the extended arm excavator is smaller than the original, so heavy work should be avoided during construction.

分厂生产的挖掘机伸缩臂成为了大多数挖掘机车主的选择，因为原厂挖掘机伸缩臂太贵，很多车主买不起。很多小工厂所用的材料也是廉价的不合格钢材，售后质量也可想而知。

The excavator telescopic boom produced by the branch has become the choice of most excavator owners, because the original excavator telescopic boom is too expensive for many owners to afford. The materials used in many small factories are also cheap unqualified steel, and the after-sales quality can be imagined.

因此，各位挖掘机车主在选择挖掘机伸缩臂厂家时要慎重，以免因贪图一时的便宜而招致不必要的损失，有条件的话，在购买前亲自到厂实地考察一下再做出选择。同时注意，挖掘机伸缩臂也分类型，需要根据自己所要做的实际工程类型选购，以免花一些冤枉钱。

Therefore, excavator owners should be careful when choosing excavator telescopic arm manufacturers to avoid unnecessary losses due to greed for temporary cheapness. If conditions permit, they should personally visit the factory before buying. At the same time, it should be noted that the telescopic boom of the excavator is also divided into different types. You need to buy it according to the actual project type you want to do, so as not to spend some wronged money.
