地铁开挖：在修建地铁工程时一切的轨迹或地基也需求运用发掘机弹性臂 才干进行，也是由于需求挖的深度高并且开槽宽，须要弹性臂才干顺畅的发挥 整理河道或鱼塘：运用发掘机弹性臂经常能运用在整理河道或鱼塘的工作 上，河道和鱼塘都是较深的工作场地，因而要发掘就需求改装弹性臂的发掘机 才干满足。
Subway excavation: During the construction of subway projects, all trajectories or foundations also require the use of elastic arms of excavators. This is also due to the need for high excavation depth and wide slot width, which requires elastic arms to smoothly organize rivers or fish ponds. The use of elastic arms of excavators can often be used in the work of organizing rivers or fish ponds, which are deep work sites, Therefore, to excavate, it is necessary to modify the excavator with elastic arms to meet the requirements.
建筑搬运运用：在各大建筑工地为了能快速的进行高层搬运土砂或混凝土 ，也会需求运用发掘机弹性臂来协助进行运送。
Construction transportation application: In order to quickly carry out high-rise transportation of soil, sand, or concrete at major construction sites, it is also necessary to use elastic arms of excavators to assist in transportation.
水利水电工程：在兴修水利水电工程时，长臂挖掘机能够根据所需求的深 度进行发掘。
Water conservancy and hydropower projects: When constructing water conservancy and hydropower projects, the long arm excavator can excavate according to the required depth.
长臂挖掘机选购注意事项：
Precautions for purchasing long arm excavators:
具体的规格参数：
Specific specifications and parameters:
通常挖掘机伸缩臂提供不同的规格参数来供购买方进行选择，不同的规格 和参数通常对应不同的土质和施工密度，因此购买方需要估算建筑工程土 地的土质以及大致的施工时间，才能有针对性的购买到适用的产品、
Usually, the excavator telescopic arm provides different specifications and parameters for the buyer to choose from. Different specifications and parameters usually correspond to different soil properties and construction densities. Therefore, the buyer needs to first estimate the soil properties and approximate construction time of the construction project land in order to purchase suitable products with targeted methods
设备的细节处理：
Equipment details handling:
使用中设备会承受较大的作用力，因此设备的每一个零部件都要求质量过 关坚固耐用，这样才能保证它能够承受长时间的使用压力。因此施工方在选购 时，原则上应当对产品的细节部分进行详细的辨别，对零部件的材质的品质进 行考量。
During use, the equipment will withstand a large amount of force, so every component of the equipment must be of good quality, sturdy and durable, in order to ensure that it can withstand long-term use pressure. Therefore, when selecting and purchasing, the construction party should, in principle, carefully distinguish the details of the product and consider the quality of the materials used in the components.
