Tunneling Used Jumbo machines megasize tunnel boring Rig For Mining
KJ311 hydraulic tunneling drilling rig is suitably qualified for the drilling of hard rock mine whose section falls in the range of 12-35 square meters.The firm flexible boom is capable of optical coverage of the section; 360°rotation and self-leveling beam make drill positioning easy ; lt can also be used for the drilling of lateral cross-cut and rock bolt; The drill rig provides a good view for the operator; balanced layout and the articulated chassis of four-wheel drive ensure the flexible,fast and safe driving in the narrow tunnel; The stepped piston is used for the high-frequency impacting rock drill and this can improve the transmission efficiency of impact wave and drilling speed and reduce the consumption of drilling tools and make it in good condition; Considerable space and automatic functions enable the driver to concentrate on drilling in a safe,fast and accurate manner; All the relevant parts are kept in good protection, meanwhile maintenance easily.
Features
- Safe and stable travelling system
With a low gravity centre and big ground clearance, this drill machine can easily travel on bumpy roads. It is driven by a special wheel motor which brings strong grade-ability and a low failure rate.
- Powerful and reliable engine
Adopt a famous 4-cylinder diesel engine as the driving force which has advantages of large power, small volume, small vibration, and reliable operation.
- Powerful feed mechanism and rotating system
Optimally designed luffing mechanism and round drilling boom with the advantages of neoteric structure and easy maintenance greatly improves the drilling hole's coverage area. That also makes low-order horizontal hole drilling available.
