液压挖掘机的工作与操作性能

The working and operating suitabilities of hydraulic excavator

近年来 ,计算机控制技术、电子液压系统、检测技术等广泛应用于挖掘机的各个机构和系统 ,使液压挖掘机得到迅速发展 .主要从挖掘机的力量和速度、行走双速化和自动变速、超小回转性及控制性能等方面分析目前世界液压挖掘机工作性能和操作性能的发展状况 .

The computer controlling technology,electronic hydraulic system,check and measure technology and so on have been widely used in each machine and system of hydraulic excavator in recent years.And the excavators have been developed rapidly.The developing situation of the excavators in the working and operating suitabilities in the world from the force and speed,stepped double speed and auto shift, exceed small turn round and controlling suitability has been analyzed.
