It is widely used for geological general investigation and exploration,road and tall building foundation exploration,kinds of hole in concrete structure,river levees,subgrade grouting hole drilling and direct grouting,civil wells and earth temperature cantral air-conditioner,etc.53*59 drilling rod adopted,high rigidity, and strong delivery torque.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 compct,mobile and lightweight.
