Power: Two sets of 559Kw/rPm Chongqing Cummins. They could work separately according to the working conditions. If two motors work together, they could achieve the max. torque, the max. rotary speed, the max. Pushing and pulling force and the max. pushing and pulling speed. The change of oil pump or output of motor could adjust the returning and pulling and pushing speed. But they couldn’t be in the condition of the max. working pressure and the max. output at the same time. They should be in the opposite side.
If it is one motor under working, it could adjust oil pump or the output of motor to change the torque and rotary speed. If reduce the output of motor, the rotary speed will keep the same and the torque is lower. If reduce the output of the oil pump, the torque will keep and the speed become lower. If close some of the pulling and pushing motor or reduce the output of motor, it could keep the pulling and pushing speed but the pulling force reduced. Two of them could interchange to work. The un-work pushing and pulling machines are separated from the clutch. The design not only saves the fuel as well as prolongs the life.

|
|
The rotating and pushing & pulling of rotary driving head adopt the close circuit. Other assistant mechanism adopts open circuit. Clamp adopts load sensitive control, which could protect the system, extend the life and use less fuel. |
|
The main body and power station adopt supporting board type, which makes transportation much more conveniently. |
|
12 sets of pulling and pushing motors operate by manual clutches and could be interchanged, which prolongs the life of motor and speed reducer. |
|
The rack and pinion is adopted by the pushing & pulling transmission of rotary driving head. |
|
The movable main axle makes unload the drill rod conveniently. It eliminates the load and avoids mud leaking. |
|
The movable beam is convenient to carry up and down, to transport and adjust entry angle. |
|
The front and back clippers could be apart and the clamp could move within the whole distance. It could exchange the jaw grips according to drilling rod. |
|
It is controlled by wire |
|
The pushing & pulling speed and rotating of rotary driving head could be entire pole less proportion linearity speed regulated. Hydraulic motor speed could be set on three levels. Working pressure within the range could be controlled by long distance, which could be adjusted the torque and pull and push force. |
|
It is equipped with mud pressure release mechanism |
|
It is equipped separately with heating and cooling systems for hydraulic oil. |
|
The operating room is separated, which is comfortable with good vision and several seats. It is equipped with cooling and warming air conditioner. |
|
One side and the back of the main beam are equipped anti-slippery pathway and protecting rods. |
|
All data displaying is easy to inspect and control. The hydraulic system shows the pressure of hydraulic system anti-shock, which is more reliable. |
|
The mud pump station and the mud mixed system are outside separately, which can be buyer’s option. |
