Main features：
◎NYT300BZ trailer mounted drilling rig is designed by our engineers; it is adopt trailer mounted and is a rotary drilling rig.
◎This rig is a rotary drilling rig with directional circulation, which can drilling together with BW850/2A or 4PN 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.
◎The power of drilling rig comes from the diesel engine; the rig sets up distribute implement.
◎The master driving of rig is mechanical, the four jacks ,mast, distribute box, sewage pump, master driving clutch system are machanical operated.
◎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.
