2.Technical Features
Schematic diagram of borehole drilling over the belt
Borehole can be drilled by ZDY3500LP without pulling down the belt
CCTEG
2.Technical Features
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
2.Technical Features
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.
