Drill height adjustment, range from 1.45m ～ 2.55mDrill Inclination angle adjustment, range from-90° ～ +90°Good manual, all hydraulic control, operating the valve's hand shank

Multi degree of freedom mechanism

CCTEG


Easy to turn the direction of the rotary unit

In order to drill a borehole with inclination

angle from -90 ～ -60 degree, rotary unit

should be turned by 180 degree.
