JK730-2 Automatic Crawler Mounted DTH Drill Rig is theair-compressor separated hydraulic DTH drill rig.Itequipped with automatic pipe changer for pipe storage,changing and connecting automaticallyly, as well as holeocating device and luxurious cabin. Sate and comfortableoperation environment substantially reduces labor intensiItyand curtails labor numbers. In contrast to the all-in-onerigs, JK730-2 is featured by its convenient operation andmaintenance as well as low downtime rate.
驾驶室
全封闭驾驶室配置带冷暖空调，FOPS达到欧美劳动保护标准。
全方位安全玻璃宽广清晰、使得驾驶者对各个角度准确掌控。超过400mm的离地间距，满足多种严苛路面通过要求，减少底盘碰撞
可能
Cabin
The sealed air-conditioned cabin is made with FOPS whichmeets EU and US safety protection standards.
The all-around large safety windows offer great visibility andhelp the operator control the rig precisely from all angles.
The high ground clearance of over 400mm suits varieties oftough terrain and minimizes the possibi lity of collision with ground.
操作系统
操作系统简洁友好，易于上手。钻机的工作运行参数、提示、报警功能集中在仪表台上，便于操作者观察，各项数据一目了然。钻机的开孔角度实时显示，方便操作者准确布孔，掌控全局。
采用先导液控系统，左手柄集合了接杆、卸杆、机械手开合及钻杆倒库所有功能，单手可以实现自动接卸杆的所有动作。右手柄集合了推进、回转等打孔功能于一体，同时带有打钻锁定功能，操作省时省力。行走采用双液控操作系统，行走平稳，性能稳定可靠。
Operation system
The operation system is simple and ergonomically-friendly. Therigs operating parameters like real-time drilling angle, instruc-tions and warnings all can be clearly displayed on the dashboardeasy for the operator to monitor and control the drill rig.
It adopts hydraulic pilot control system. The left joystick incorporates the functions like connection and disconnection of the drillpipes, control of the mechanical hands, rotation of the pipecarousel. All the movement for automatic pipe connection anddisconnection can be achieved by one hand. The right joystickgathers the drilling controls to feed, rotate, etc. And the drillingcan be automatically set to make operation easy and save time.The traveling of the drill rig is controlled by double hydraulicsystems which ensure the traveling stability and feature high reliability.
发动机进气系统
三级空气过滤系统保障入气清洁，同时降低空滤成本，大大降低发动机故障率。
Air intake system
Three-stage air intake system ensures the cleanliness of the air and lowers the cost of the air filters, significantly reducing the engine'sfailure rate.
回转机
双摆线马达回转装置，回转扭矩大、不容易卡钻，同时可以根据不同岩层调节回转速度。回转密封件，密封性好、寿命长。
Rotation un
The double cycloid motors can output massive torque and reducepossibility of pipe-stuck situation. And the rotation rate can becontinuously adjusted according to different rock formations.
The seals for the rotation unit is with extraordinary performanceand long service lite
液压除尘系统
全液压除尘器，带有滑动式捕尘罩。收尘效率高，性能稳定，有效的延长了钻机的使用寿命，环保效果好。
Dust collecting system
The efficient hydraulic dust collector is equipped with a slidingdust cover. It boasts high dust collecting efficiency and stable performance, extends the rigs service life and ensures a cleanworking environment.
底盘
工程机械四轮一带底盘，结构强度好，兔维护。加宽履带行走平稳，爬坡能力强，凿岩作业时更加平稳。
浮动式车架，浮动角度±10°。行走高低双速可调，工地间转移快捷。
Undercarriage
The maintenance-free heavy duty undercarriage features robuststructural strength, wide tracks and excellent grade ability, whichall ensure better stability while drilling
The undercarriage can oscillate +10 back and forth, featuringadjustable dual speed and fast maneuverability between sites
维护保养
维护保养便利，保养点和检查点触手可及，发动机舱布局合理，多个机罩门开合方便，使得保养和服务十分便捷。
Repair and maintenance
Mmaintenance and repair are very convenient thanks to that themaintenance and check points are easilyaccessible, engine com-partment is well organized, and all service doors can be easily opened and closed.
