The HZ-130/180/200 series core drilling rigs are suitable for rigorous exploration, geophysical exploration, road and building exploration, and blasting holes. Drills such as alloys, diamonds and composite sheets can be used depending on the bottom layer. It can drill 2-9 grade sandy clay and rock layers.

· With hydraulic automatic feeding mechanism to improve drilling efficiency and reduce labor intensity.

·The ball card clamping mechanism can be used instead of the chuck to implement the non-stop bar, which is easy to operate, safe and reliable.

·The hoist is equipped with a cage to form a double-sided support star wheel structure, which can withstand strong impact

·The four sets of bearing positioning of the vertical axle box ensure that the gyrator has sufficient rigidity to deal with complex geological conditions such as gravel layer and pebble layer.
