长臂挖掘机的特点是具有比常规型挖掘机更长的臂杆，其长度通常可以达到比挖掘半径多两倍的长度，这样在挖掘深度达到6~10米时，具有更强的作业能力。不仅适用于土方工程、建筑工程、生产制造业、煤矿等行业的工程机械，在抗洪抢险、抗震救灾等自然灾害的救助过程中，更能发挥其作用，率、低成本地挽救生命财产。

The characteristic of a long arm excavator is that it has a longer arm than a conventional excavator, and its length can usually reach twice the excavation radius. This way, when the excavation depth reaches 6-10 meters, it has stronger operational capabilities. Not only suitable for engineering machinery in earthwork, construction, manufacturing, coal mining and other industries, but also in the rescue process of natural disasters such as flood control and earthquake relief, it can play a more efficient and low-cost role in saving lives and property safety.

按照工作用途和特性的不同，长臂挖掘机可以分为以下几类：

According to different job purposes and characteristics, long arm excavators can be divided into the following categories:

标准型长臂挖掘机：这是一种常见的长臂挖掘机，其标准臂长为10-18米，适用于建筑施工、道路建设、深基坑开挖、地铁等工作。

Standard long arm excavator: This is a common type of long arm excavator with a standard arm length of 10-18 meters, suitable for construction, road construction, deep foundation pit excavation, subway and other work.

深型长臂挖掘机：这种型号的长臂挖掘机配备较长的臂杆，可以轻松实现20-30米长臂高空作业或在深达20-30米的地下进行挖掘。

Deep type long arm excavator: This model of long arm excavator is equipped with a longer arm, which can easily achieve high-altitude operations with a long arm of 20-30 meters or excavate underground at depths of 20-30 meters.

经济型长臂挖掘机：这种类型的长臂挖掘机在保持主要功能的情况下，减少了一些辅助设备和部件，从而降低了成本。适用于一些追求性价比的领域。

Economy type long arm excavator: This type of long arm excavator reduces some auxiliary equipment and components while maintaining its main functions, thereby reducing costs. Suitable for some fields that pursue cost-effectiveness.

大型挖掘机：这种长臂挖掘机主要用于矿山、沙石场、森林采伐等重型工作环境中，可以进行大量土方工程，其挖掘深度和臂长都非常大。

Large excavator: This type of long arm excavator is mainly used in heavy working environments such as mines, sand and gravel fields, and forest logging. It can perform a large amount of earthwork engineering, and its excavation depth and arm length are very large.
