Gl120y hydraulic crawler drill rig powers the moving of the oil hydraulic motor, rotation, propelling and lifting,
Swing angle location etc. By diesel engine( or electromotor) driving the hydraulic oil pump.
It could match with dth hammer and bit for the hard rock drilling or auger drill rod for the medium-soft formation drilling.
Gl120y is good for blasting hole in surface mine, water electric building, road construction and piling project.
