Now, in many projects, we can see the figure of the long arm excavator. As a large-scale heavy industry equipment, the extension arm is a group of front-end working devices specially designed and manufactured to expand the working range of excavator according to the requirements of working conditions. Why do excavators need long arm? What are the advantages of long arm excavators over ordinary excavators? In fact, we can guess from the literal first that the working range of the long arm excavator will be larger to meet the working conditions that ordinary excavators cannot achieve. The specific advantages can be seen in the detailed introduction of the long arm excavator rental manufacturer:

一、施工效率高、进程更快

1、 High construction efficiency and faster progress

相较于人工劳力，挖掘机加长臂的施工效率便颇为显着，其臂内装有内部缓冲板以承受张力负载，保证了加长臂的结构强度、使用性能和质量，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。

Compared with the artificial labor, the construction efficiency of the long arm of the excavator is quite remarkable. The inner buffer plate is installed in the arm to bear the tension load, ensuring the structural strength, service performance and quality of the long arm, not only improving the construction quality but also shortening the construction time, greatly promoting the construction process.

二、适应性强、作业范围广

2、 Strong adaptability and wide operation range

挖掘机加长臂能适应多种环境条件作业，如深坑作业的地基工程，高空作业的楼房拆卸或河道清理等领域的建设和维护等，都用到加长臂才能快捷地完成工程要求的各项指标。

The long arm of excavator can adapt to a variety of environmental conditions, such as the foundation engineering of deep pit operation, the demolition of high-altitude buildings or the construction and maintenance of river cleaning and other fields, all of which need the long arm to quickly complete the various indicators required by the project.

三、机械化程度高

3、 High degree of mechanization

长臂挖掘机机械化程度高，施工组织简单方便操作，可加速工程的进程，在一定程度上节约了人工的成本。

The long arm excavator has a high degree of mechanization, simple and convenient construction organization, which can speed up the process of the project and save the labor cost to a certain extent.

四、降低事故

4、 Reduce safety accidents

华体会国际 降低了事故的发生，长臂挖掘机它的操作灵活且在使用范围广，能很好的操作人的力量操作不到的地方，可减少施工过程中的危险。

The long arm excavator reduces the occurrence of safety accidents. The operation of the long arm excavator is flexible and has a wide range of use. It can operate well where the power of the operator cannot reach, and reduce the risk in the construction process.

从上述我们可以发现，华体会国际 可以铺设到其他难以到达的地方，可以满足各种施工要求，且质量有保障。二期还提高了施工效率，加快进程。

From the above we can find that the long arm excavator can be laid to other hard to reach places, can meet various construction requirements, and the quality is guaranteed. The second phase also improved the construction efficiency and accelerated the process.
