Multi-functional crawler well drill is a new efficient and multi-functional hydraulic well drill. It is mainly used in drilling operation such as drilling well,monitoring well, relief well exploiting coal gas and other exploratory hole projects.
In stone drilling, DTH hammer is applied in the operation, slag is discharged by air pressure and the offstage efficiency is ten times of the traditional rotary drill.
Cutting drilling or cone drilling can be operated in the unconsolidated layer,the slag can be discharged under the effect of slurry;The impact drilling operation can also be adopted and the slag can be discharged by air pressure;the machine is suitable for drilling in the complicated geological conditions; The maximum drilling depth is 700m, the drilling diameter is 140mm-450mm.
