液压挖掘机能够进行挖掘、装载、卸载和整机移动，比装载机更能适应恶劣的环境。随着液压挖掘机的使用范围的迅速扩展，为适应不同工程对象的施工要求和市场竞争的需要，对常规的中小型挖掘机而言，要求增多工作装置，以适应多种作业的需要。本文就根据用户的需求，对ＷＹ２０?
Hydraulic excavators are capable of digging, loading, unloading and moving the machine to better withstand harsh environments than loaders. With the rapid expansion of the use of hydraulic excavators, in order to meet the construction requirements of different engineering objects and the need of market competition, conventional small and medium-sized excavators are required to increase working devices to meet the needs of various operations. This article according to the needs of users, the WY20?
