With the continuous development of the machinery industry, more and more large machinery contribute to the construction industry. Large machinery such as the excavator extension arm can be reused, because efficiency can make it better serve us. However, some people still doubt how efficient it can be. Let's go and see how the excavator extension arm is!

如今社会在高速运转，使得各种设施都在加码建设，公园的绿化完善，地下停车场的车位增加，商业设施等，就连自建的楼房都需要用到挖掘机加长臂，因为比起人工，它的效率实在是太高了，凭什么它的效率就可以那么高？因为它有着不一样的工作能力，动力充足的液压装置，无论是对建设开垦地基还是对河道治理方面都很强，而且适用的领域很广泛，从来不挑食，只要是工程项目就可以看到它的身影。

Nowadays, the society is running at a high speed, so that all kinds of facilities are under construction. The greening of the park is perfect, the number of parking spaces in the underground parking lot is increased, commercial facilities, etc. Even the self built buildings need to use excavators to extend their arms. Because its efficiency is too high compared with manual work, why can it be so high? Because it has different working capacity, the hydraulic device with sufficient power is very strong in both construction and reclamation of foundation and river regulation, and it is applied in a wide range of fields. It is never picky. It can be seen as long as it is an engineering project.

现在社会什么都要讲求效率，如果效率不行，必然会被淘汰。像挖掘机加长臂不仅效率方面做得很好，而且工作也是做得很好，正是因为它有这样的能耐，所以才越来越多受欢迎，而且对机械行业和基础建设来说，是必不可少的好帮手。

Nowadays, society should pay attention to efficiency in everything. If efficiency is not good, it will be eliminated. For example, the excavator extension arm is not only good at efficiency, but also good at work. It is precisely because of its ability that it is more and more popular, and it is an indispensable good helper for the machinery industry and infrastructure.
