1.The applications of HZ-200YY drilling rig
HZ-200YY drilling rig is mainly used for water well,field irrigation well,engineering water well,precipitation well and so on;geological general investigation and exploration,road and tall building foundation exploration, holes in concrete structure,river levees.
2.The features of HZ-200YY drilling rig
¬The highest speed can reach 1045r/min with 5 gears, improved drill efficiency
¬Adopted 53 x 59 drilling rod, high rigidity and strong delivery torque
¬Equipped with national patent technology---taper clutch, make the machine easy to operate and free maintenance.
¬Use large module planetary gear and add supporting frame, highly increased hoisting and braking ability of the winch.
¬Vertical spindle are fixed by four groups of bearings to ensure that the rotary machine is rigid enough for gravel layer and other complex geological conditions.
