KT11S Type open hole drill is based on developing and producing DTH drills for many years, according to the demand of large open-pit mine, and is an elaborate design new drilling equipment. The Drill walking forward, turning and angle adjustment and other movements adopts hydraulic driven. With the impact of high wind pressure screw and pneumatic impactor, it have high drilling productivity. Equipped with hydraulic dry dust collector to collect dust collection can reduce the pollution to the environment. Also with the hydraulic manipulator and drill pipe library , floating coupling to protect the drill screw, only one person can dismantle the pipe. The air conditioning cab to provide a comfortable working environment, automatic control valve to reduce the card stuck drill chance. Drill car has a high degree of automation, energy efficient, comfortable environmental protection, easy to operate, flexible and adjustable, and safe driving etc. characteristics.

Down The Hole (DTH) drill rig capable of drilling to a depth of 300mtrs (1000 ft) under favorable drilling condition. The drill rig can be operated on rocky formation and hard to medium soil formation. The drill rig can make a hole of diameter 4 to 6.

The drilling rigs can fully meet the well-drilling- process requirements by adoption of flexible driving designs- mechanical drives (high-speed diesels, hydraulic transmission box, angle gear box or middle-speed diesel hydraulic transmission, chain combination box), compound transmission and electrical drives (VFD or SCR) etc. * The whole unit is very compact and a quick whole transportation and installation of the whole drilling rig can be realized due to a utilization of a skid-mounted structure. In addition, the drilling rig requires a small working site due to its high integration and compact configuration. * Masts and substructures have various structures, such as: perpendicular-hoist sectional mast, whole-hoist K-type mast, telescopic substructure, spirally hoisted substructure and folding - frame substructure. * A standard and module design and various ways of combination have been adopted in order to boost up the universal and exchangeable performances of the drilling rigs and to meet the user different requirements. * Disc brake or band brake can be applied as main brake and air brake or FDWS brake can be used as auxiliary brake and the energy-consumption braking can be available for electrical-drive-rig auxiliary brake. The drawworks can be equipped with bit-feed motor and control system. * The Internet and communication techniques have been used on the drilling rigs, which can realize an integral display for power, air control, hydraulic control, and monitoring and the intellectual and safe control of the driller. * The perfect configurations of the solid control system, well control system, high-pressure pipe manifold system, the generator house, the engine pump house, doghouse and other auxiliary facilities can meet the user different requirements. Safety and inspection measures are strengthened under the guidance of the design concept of ° Humanism Above All¡± to meet the requirements of HSE.
