1. NYT1500 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 BW1200/7 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 power is 269kw, the brand is Cummins; the rig sets up distribute implement and hydraulic system. The rig has three motors, and the force were sent to the transmission system, mud pump and hydraulic system.
4. NYT1500 trailer mounted drilling rig used K-type two paragraph telescopic drilling tower, the tower is lifted up by hydraulic cylinder. It is installed the lights on top, middle and bottom of the tower, in order to works at night. The tower exxective height is 16.5m, the bearing capacity not less than 60t.
5. It is installed 4 hydraulic legs and 2 mechanical legs, every hydraulic leg rod with locknut. After leveling the rig, it can lock the cylinder use locknut. So, even if the cylinder leaks, the chassis is not instability.
6. It is installed a generator (50kw) , so that it is convenient to illuminate or work at night.
