求翻译：采用先导操作装置，降低操作杆所需力度，提高作业效率，降低驾驶员疲劳度；搭载标准双速行驶系统，在大型作业场地，可使用高速行驶速度从而提高作业效率。是什么意思？

Pilot operated device used to reduce the required operating lever, improve operational efficiency, reduce driver fatigue; equipped with standard two-speed drive systems, large-scale operations in space, you can use high speed to improve operating efficiency.

A pilot operating devices operating rod, and reduce the required efforts to enhance operational efficiency, reduce driver fatigue; piggyback standard double-speed system, and in large-scale operations, you can use high-speed driving speed venues to enhance operational efficiency.

Uses the forerunner to operate the installment, reduces the operating lever to need dynamics, enhances the work efficiency, reduces the pilot fatigue; Thus the embarkation standard two speed travel system, in the large-scale work location, may use the high speed moving velocity to enhance the work e

Use of pilot plant operation, reduced lever the desired intensity, improve work efficiency, reducing driver fatigue; carrying a standard two-speed system in large job sites, you can use the high speed so as to improve operation efficiency.
