Borehole Drilling Machine for Hard Rock (HW-230)
1.HW-230 water well drilling rig Feature
A.53*59 drilling rod adopted,high rigidity and strong delivery torque.
the machine is equipped with national patent technology---taper clutch,with charactristics of strong transmission troque,easy operation and free maintenance.
B.for the winch,we use large module planetary gear and add supporting frame,greatly increasing hoisting and braking ability of the winch.
C.vertical spindle are fixed by four groups of bearings to ensure that the rotary machine is rigid enough for gravel layer and other complex geoloical conditions.
D.we are the first one to equip mud pump with the flow 160L/min in china so that it will save cost and also make the machine compact,moblie and lightweight.
2.HW-230 Water Well Drilling Rig Applications
HW-230 drilling rig is mainly used for geological general investigation and exploration,road and tall buliding foundation exploration,kinds of hole in concrete structure,river levees,subgrade grouting hole drillling and driect grouting,civil wells and earth temperature entral air-conditioner,etc.
