挖掘机加长臂的出现就是为了能够更好地应对硬核工程的，所谓的硬核工程就是那些工况难度高工程，但是难度再高度难不倒我们的，毕竟我们现在能将挖掘机加长到一定的长度，专门来应付这些高难度的工况，如南水北调工程、高铁线路建设、山区移民安置区建设等这类的大型项目，而非那些小修小补的小工程。
The emergence of excavators with extended arms is to better cope with hard core projects. The so-called hard core projects are those that are difficult to operate, but no matter how difficult they are, we can now extend excavators to a certain length to specifically deal with these difficult working conditions, such as large-scale projects such as the South to North Water Diversion Project, high-speed rail line construction, and the construction of mountainous resettlement areas, Instead of those minor repairs and minor repairs.
因为小工程用不上也不需要使用像挖掘机加长臂这样较的挖掘设备，高难度的工况不仅对于操作师傅的技术考验很高，而且对挖掘机加长臂操作性能要求高，因为普通的挖掘机根本不能像挖掘机加长臂那样满足高强度高要求的作业，而小工程的资金有限，只能往往只能选用标准臂挖掘机，再加上工程的难度低，标准臂挖掘机已经足够很好地完成工程任务。
Because small projects do not require advanced excavation equipment such as excavators and extended arms, the difficult working conditions not only require high technical tests for operators, but also require high operational performance for excavator extended arms. Ordinary excavators cannot meet the high intensity and high requirements of operations like excavators and extended arms, and the funds for small projects are limited, so standard arm excavators can often only be used, In addition, the difficulty of the project is low, and the standard arm excavator is already sufficient to complete the engineering task well.
而挖掘机在工程中的切实作用才是硬核工程选它的理由，加长臂具有良好的工作能力，这个特点可以令人们能够在大面积的作业中扩大作业的范围，减少挖掘机本身的移动次数，增加挖掘的距离。
The practical role of excavators in engineering is the reason for choosing them for hard core engineering. The extended arm has good working ability, which can enable people to expand the scope of work in large-scale operations, reduce the number of movements of the excavator itself, and increase the distance of excavation.
所以很多工程采用挖掘机加长臂能为工程节约不少的时间成本。这样的大型机械其次是深挖能力，安装了加长臂的钩机简直可以用如虎添翼这个词语来形容，这种深挖能力正好能满足大工程的固定需要，所以这样的挖掘机加长臂真的很好用。
So many projects use excavators to extend their arms, which can save a lot of time and cost for the project. This type of large machinery is followed by its deep excavation ability. A hook machine equipped with extended arms can be described as adding wings like a tiger. This deep excavation ability can precisely meet the fixed needs of large projects, so this type of excavator with extended arms is really useful.
