Features

Large torque, has relatively light weight and smaller size as compared to the drill rig of the same type. Thus, it is easier for shifting purpose.
It has gantry structure, up and down moving of the power head, has strong strength, rigid and high drilling precision.
Large drilling diameter (182 x 182 mm), construction can be conducted by forward and reverse circulation drilling technique.
We adopt DongFeng EQ145/6 automobile gearbox, equipped with 6-gear clockwise rotation and 1-gear counter clockwise rotation, applicable in drilling works in various foundation conditions.
The power head equipped with manual chuck, drilling with Kelly bar. It has large depth of completely drilling and high efficiency.
The power head adopts direct feeding by the oil tank and pressurized, resulting strong pulling ability and convenient for drilling works.
Moving distance of the sliding base is 1550mm, large range of opening hole, convenient for raising or lowering the drill.
Equipped with walking mechanism, convenient for the drill rig movement and align it with the hole.
