Sa ny hydraulic rotary drilling rig SR150C
5-level anti-vibration technology absorbs drilling vibrational frequency all- directionally to guarantee high stability; The special lubricating system makes sure that it can work in high-temperature environment. Rotary drive is available in three drilling modes-standard, low speed and big torque or high speed and small torque; Spin-off is optional; The removable key of rotary drive and symmetry structure design double its service life; The main winch has highlights of touch-bottom protection, priority control and fast line speed; Crowd cylinder has two operation modes---normal lifting and fast lifting to improve push efficiency; Mast features automatic erecting, lying and vertical adjustment to ensure the accuracy requirements in construction; Balance control system of the whole machine is available.
The imported engine with original packing has strong power, and can meet the requirements of high-efficient work.
- Precise matching design with advanced energy conservation control can reduce the oil consumption of the machine.
- Low emission meets the Europe II standard.
- The adoption of new cooling fan and large-scale silencer lowers the noise of the machine.
- The adoption of the advanced turbocharging technique increases the highland adaptability of the machine.
- Automatic preheating system improves the working capacity in the low temperature.
- Unique fan cover with the shape of hopper opening greatly improves the air supply of the engine and the radiating capacity of the system, guaranteeing the successive high-efficient work of the machine.
- Restart prevention system effectively avoids the misoperation, and improve the use security of the machine.
