自主創新,精心打造,卓越的設計理念使JVR300Z旋挖鉆機擁有可靠的系統和強勁的動力,能適應各種復雜工況,具有經濟、高效、環保、穩定等多重優點。
Independent innovation, meticulously made, excellent design concept, to makes JVR300Z rotary drilling rig have a reliable system and strong power, which can adapt to various complicated conditions.Also it enjoys such multiple advantages as economic, efficient, environmental friendly and stable. 
可拓展性履帶,增加了履帶的長度和展開后的寬度,提高鉆機的穩定性;上車平臺雙減速機驅動,解決制動難題;優化配重布置并增加其重量,提高整機的穩定性和可靠性。
Self-extendable of the track, increased the track length and unfolded width, improves rig stability. Double reduction gear drives were adopted on the train platform to solve the braking problem. Weight optimization layout and increase the weight so that the stability and reliability of the machine can be improved.
液壓元件采用力士樂元器件,保證液壓系統的可靠性與穩定性;采用國際先進的設計理念,實現了流量的按需分配和精準控制,保障了傳動效果;液壓系統加入全過濾創新結構,極大地提高液壓油的清潔度,使設備運行更可靠、更經濟、更高效。
Hydraulic components adopt Rexroth components, ensuring the reliability and stability of hydraulic system. Using the international advanced design concepts realized the flow of distribution according to need and precise control, ensuring guarantying security transmission effect. Hydraulic system instilled full filtering structure innovation, greatly improving the cleanliness of hydraulic oil, making the equipment operation more reliable, more economical and more efficient.
動力頭配置三馬達、三減速機,滿足鉆機入巖大扭矩輸出;針對入巖的工況,對動力頭減震進行改進,引入減震結構和減震技術,經過現場試驗,具有明顯的減震效果。
The power head collocates with three motors and three reduction gears, satisfying the high torque output while drilling into the rock. According to the rock conditions, the power head shock absorption was improved, the damping structure and cushion technique were introduced, which has obvious damping effect through the field tests.
