The engine is CHONGQING Cummins NTA855 six cylinders turbocharged diesel engine, large power margin, assuring enough drilling power and also meet with emergency demand. Powerful and strong, the rated power of the engine is 250kW/2100rpm, the Max. Back pulling force is 680kN, the torque is 27000Nm. economical and oil saving, equipped with suction water radiator, assuring long time working.
Powered head: The power head is the main mechanism of the drill, adopting low speed high torque hydraulic motor driving, and then driving the power head output shaft, high transmission efficiency, compact, it has high and low double speed stepless regulating function, suits with different construction requirements. The floating power head has damping device, which efficiently protect the drill pipe thread. It has the follow main functions:
1. Driving the drill pipe head slewing
2. Enduring drilling and back pulling reaction
3. The mud passage entering into the drill pipe.
Pull push device of the power head: Pull push device of the power head is the mechanism performing the power head back pulling and thrusting movement, which provide the thrusting force and back pulling force to the power head through Plunger motor, reducer, gear wheel and rack transmission, high strength and running stably and durably.
The drill pipe frame can slide forward and backward, through angle adjusting oil cylinder adjust the right drill angle and Slope-climbing angle to suit different drilling requirements. Two shift stepless speed regulating, high working efficiency.

Steering system: Low speed large torque motor driving, two shift speed stepless regulating
The drill pipe frame: high intension box style drill pipe frame can slide on the machine frame, and easy angle adjusting. Gear and rack drive, stably and reliably, sliding drill pipe frame, big dip angle adjusting range, full length walk table, easy going up and down.
powerful drill pipe clamp
Powerful drill pipe clamp (holder): Radial jaw clamp the drill pipe, strong clamping strength, can whole-body float. It includes upper clamp and lower clamp, located in the front of the sliding frame; the upper clamp has clamp and rotating double actions. The upper and lower clamps act assorting with the rotation and movement of the power head to perform tightening and loosening the drill pipe thread. The drill pipe clamper (holder) is driven by motor and moves forwards and backwards on the drill pipe, and the space between front and rear clamps is adjustable. The clamper and onboard crane make the drill pipe assembling and disassembling with much easy, high efficient and labor saving.
The anchoring device: the anchoring device is playing anchoring function, located in the front of the drill; it can raise the whole drill stability.
Onboard crane: 360°rotating straight arm telescopic jib crane, convenient for assembling and disassembling the drill pipe and lifting the drill tools and other drill tools, reduce the labor intensity, improve the working efficiency.
Driving cab: adopts Man-Machine Engineering driving cab. Double, single all weather driving cab, steering and operation are centralized in the driving cab, wide eyeshot, all kinds of instruments monitor the drill, cold and warm air conditioner, car seat, comfortable operation.
Mud pump system: Mud pump is horizontal three throw reciprocating and single action piston pump, which is driven by hydraulic motor. 600L large flow Mud pump manufactured by Hengyang tan Kuang Company is equipped with machine. 10CBM mud tank is for option.
Drill pipe, drill tools: can select to equip shanghai bao gang or bohai nengke produced oil drill pipe. Reamer can select flaring reamer or expanding and enlarging reamer, the diameter is from 400mm to 1000mm.
Pilot system:adopting wired or Wireless directional control system.
Electrical system Mainly includes: startup of engine, flame-out of engine and checking, walking control, mud pump control, clamps control, clamp control, and pull push and rotating control to the power head, throttle control, the front and rear stop control of the power head. And also monitor the parameter of engine and hydraulic system and safety protection. It consists of left controlling platform, right controlling platform, auxiliary controlling platform, instrument box, travel control box.
Engine and light alarm: this machine adopts 24V single wire system power supply, minus earth system. Double 12V storage battery series with the generator supply the electricity to the whole machine. The machine start electricity is provided by storage battery, after the machine is started on, the generator will supply the 24V DC to the whole machine and also charging the storage battery at the same time. Press down the STOP knob or emergency switch will let the engine stop work.
Water thermometer: the engine water thermometer is used for indicating the engine coolant temperature, once the water temperature is over the set value, the water temperature alarm switch will close, when the Water temperature warning indicator light, stop the machine and check.
Oil-pressure gauge: it indicates the oil pressure of the engine. When the oil pressure is lower than the set value, the oil pressure alarm switch will close, oil pressure indicator lights,( the light will light even the engine stopped, it is the normal condition), and stop the machine and check.
Fuel gauge: fuel contents gauge of the engine. If the fuel content is low, should add more fuel inside.
Tachograph: Indicating the current rotating speed.
Engine hour meter: it is indicating the engine working hour's meter.
Voltmeter: indicating the Voltages of Electrical Systems,
Alarm indicator lamps
Oil filter alarm lamp: when the hydraulic filter blocked, the sensor will light, under this condition u should clear or change the oil filter
Warning light to low oil pressure and high water temperature of engine: Once the indicator is light, should check the engine instantly.
Throttle control: through the throttle switch commutating the power source optimistic and negative of the throttle driver, controlling the clockwise and positive rotation of the DC stepping motor, let the throttle forwards or backwards to open the throttle or reduce the throttle
Walk control: through pushing or pulling back the travel handles of the left and right crawlers the electro-hydraulic proportional valve is to be controlled, so to realize the whole machine going forwards ,backwards or turning around,
Emergency stop: under emergency shut off the engine
Function switches:

The power head push pull: through the operation of handle forward or backward, control the electro-hydraulic proportional valve of the power head push pull, also realizing the power head with high speed push pull.
Clamp control: clamp tightening and rotation, clamp separation are realized though related switches controlling the valves.
Rotation brake: through related switches controlling the valves to realize the power head rotating brake.
Forced push pull: when the power head touched the front and rear limit switch, the power head will stop, press this push-and-pull forced switch, the power head will continue run.
Television monitoring system (option): it includes color TV receiver, security camera and so on, through color TV receiver, security camera you can see the back corner, in the spare time you can watch television programs.
