The extended arm of the excavator not only has no restriction on the terrain, but also can be used in the city. It can also run steadily on high slopes, low slopes, and even in the mud, and the operation is very smooth. This is a living tank-type excavator extended arm, which can do everything through mountains and seas, and can also be used to demolish buildings and foundations. These functions may be rarely touched by everyone, In addition, the work ability in building demolition is particularly strong. In the past, building demolition was used for manual demolition, and it was slowly knocked from the top of the building layer by layer. Now it can be completed directly by using the excavator lengthening arm, which is much faster than manual work, saving time and labor. Now is the era of pursuing efficiency, so the excavator lengthening arm is often used for building demolition.

在设计上，需均按挖掘机机型匹配设计，从挖掘机加长臂工作性能，性能等综合方面考虑与设计，保证挖掘机加长臂的质量，但是还是要再新机改装前须与整机销售商达成相关协定。挖掘机加长臂不仅提高了施工质量也缩短了施工时间，极大地促进了施工进程，所以说挖掘机加长臂属于施工过程中必不可少的机械设备。

In terms of professional design, it is necessary to match the design according to the excavator model, and consider and design from the working performance, safety performance and other comprehensive aspects of the extension arm of the excavator to ensure the quality of the extension arm of the excavator, but it is still necessary to reach a relevant agreement with the seller of the complete machine before refitting the new machine. The extension arm of the excavator not only improves the construction quality, but also shortens the construction time and greatly promotes the construction process. Therefore, the extension arm of the excavator is an essential mechanical equipment in the construction process.

挖掘机加长臂在地基建设方面也是一样厉害。在以前靠人工挖又费时费力，效果也不是特别好，而且挖得越深渗水就越严重，那么人工去开挖的时候就很不方便，而且还有一定的危险，现在都是挖掘机加长臂去开挖，旁边有运输车，那么一铲一铲地挖上来就可以直接被运走，而且挖掘机加长臂挖出来的边缘很整齐，又不惧怕渗水，这样一机多用又省时省力的大型机械当然受大家的追捧拉

The extension arm of excavator is equally powerful in foundation construction. In the past, manual excavation was time-consuming and laborious, and the effect was not particularly good, and the deeper the excavation, the more serious the water seepage, so it would be very inconvenient to excavate manually, and there was a certain risk. Now, it is all excavators with long arms to excavate, and there is a transport vehicle next to it, so it can be directly carried away after digging up by shovel, and the edges dug out by the excavator with long arms are very neat, and they are not afraid of water seepage, Such a large machine with multiple uses and time and labor saving is certainly popular

都知道挖掘机加长臂是河道清理常用的挖掘机机械，灵活操作又效率高，保障好水环境，又能将施工对水环境和景观的影响降到，挖掘机加长臂真是超乎想象的率

We all know that the excavator extension arm is a commonly used excavator machine for river cleaning. It is flexible and efficient, and can protect the water environment and minimize the impact of construction on the water environment and landscape. The excavator extension arm is really beyond imagination
