国机重工GE380H型挖掘机采用了新型的液压系统,使用大排量主泵、大流量主阀,具有通流面积大,压力损失小,流量分配合理,协调性好的特点。此外,国机重工GE380H型挖掘机还拥有动臂优先、斗杆再生、防沉降、铲斗合流、耐高压液压缸、液压单向节流阀等技术;产品配备了大缸径液压缸,并优化各关键铰点的布置,提升整机挖掘力;GE380H具有设置自动增压功能,可随着负载的增加而自动增加挖掘力。以上特点使得操作手在实际工作时,比操作同吨位其他品牌产品更加轻松。国机重工GE380H采用加强型动臂、斗杆,连接部位采用整体高强度低碳铸
National Heavy Industries GE380H excavator using a new type of hydraulic system, the use of large-displacement main pump, the main flow valve, with a large flow area, pressure loss, flow distribution and reasonable coordination of good features. In addition, the GE380H excavator also has a boom priority, stick regeneration, anti-settlement, bucket confluence, high pressure hydraulic cylinder, hydraulic one-way throttle technology; products equipped with a large cylinder hydraulic cylinder and optimize The layout of the key points to enhance the machine digging force; GE380H has set up automatic boost function, with the increase of load automatically increase digging force. The above features make the operator in the actual work, than the operation of other brands with the tonnage more easily. National Heavy Industries GE380H using enhanced boom, stick, connecting parts using the overall high-strength low-carbon casting
