hydraulic excavator

基本解释

This is a 1.5 m long hollow cylinder apparatus, can use the elevator shuttle to hydraulic excavator through food channel.
这是一根长1.5米的空心圆柱状设备，可以利用升降机穿梭于液压挖掘机打通的给养通道。
Energy saving with electronic control is one of developing hot spots in system design technology of hydraulic excavator. Intelligent control must be a developing direction.
电子节能控制是液压挖掘机系统设计技术的发展热点之一，智能化控制是必然发展方向。
The whole project is expected to take 4 months, but due to the Australian manufacturing hydraulic excavator and the rig is very advanced, more than 1 months to finish the task.
整个工程原本预计要耗时4个月，但是由于澳大利亚制造的液压挖掘机和钻机十分先进，1个多月就完成了任务。
