全球首臺以Cat345GC底盤生產的旋挖鉆機。
The first rotary drilling rig produced by Cat345GC chassis in the world. 
節能、智能、HT入巖顯魅。
Energy saving, intelligent, HT entering - rock shows charm.
高效電控液壓系統,自動調整液壓功率各發動機轉速來匹配所需工作條件,液壓系統效率高、損耗小。
High efficiency electric control hydraulic system, automatically adjust the hydraulic power of each engine speed to match the required working conditions, high efficiency and low loss of the hydraulic system.
動力頭多檔控制,可滿足多種工況的需求,施工高效,油耗低。
Power head multi-step control, can meet the requirements of various working conditions, high construction efficiency, low fuel consumption.
動力頭與主卷復合動作,有效防止吸鉆,提高施工效率。
The combined action of power head and main winch can effectively prevent absorption and improve working efficiency.
主卷揚防溜桿設計,通過匹配主卷揚換向閥、主卷揚平衡閥、主卷揚制動閥的啟閉特性曲線,防止主卷揚裝置失效,降低主卷揚溜桿發生概率,極大提高了主卷驅動系統的可靠性。
By matching the opening and closing characteristic curves of the main winch reversing valve, main winch balance valve and main winch brake valve, the design of the main winch anti-slide rod prevents the failure of the main winch device, reduces the probability of the main winch anti-slide rod, and greatly improves the reliability of the main winch drive system.
單層繩主卷揚,提升力大,鋼絲繩壽命長。
Single layer rope main winch, with large lifting force and long life of wire rope.
