1. NYT-300 trailer mounted drilling rig is designed by our engineers; it is adopt trailer mounted and is a rotary drilling rig.
2. This rig is a rotary drilling rig with directional circulation, which is equipped with BW850/2A mud pump. It adopts the slurry as the washing fluid, it can drill on clay, sand and rock if it is equipped with a good drilling bit.
3. The power of drilling rig comes from the diesel engine; the rig sets up distribute implement and hydraulic system.
4. The adding pressure implement is hydraulic, so it has a high efficiency when the rig drill on mud rock and weathering formation through using the adding pressure implement.
5. The master driving of rig is mechanical, the four jacks and mast are hydraulic operated. Distribute box, sewage pump, master driving clutch system are air operated.
6. The appearance of rig is pretty. It has a high efficiency because of having a larger torque of the turntable, it is mainly used for water well, construction, national defense building foundation, geological exploration, geothermic well and other foundation working. It is popular with domestic and foreign clients.
