KP2200 Full Hydraulic pressure piling driver used in Wuhan changjiang river bridge construction

1.This hole drilling rig adopts full hydraulic pressure drive, constant power variable loop, and makes drilling machine change rotary speed and increase Torque automatically according to the variation of stratum in the in the course of engineering construction.

2.It adopts wheel cylinder startup and electrohydraulic multiple operation. It utilizes the technique of reducing the pressure automatically to drill to ensure pore forming vertically.

3.This drill adopts the deep drilling technique of positive and negetive circulation which increases the effeciency of  drilling.

4.It applies to various stratum and is the first selected equipment for the basic construction of river bridge and dock, and also applies to drilling project of high building and heavy caliber shallow well.

5.Major Diameter Drilling Equipment has double layers bottom plate.
