1. Gl120y high air pressure dth drill powers the moving of the oil hydraulic motor, rotation, propelling and lifting, swing angle location and so on by diesel ( or electromotor) driving the hydraulic oil pump.
2. The dth hammers consumes the pressure air only when drilling. It can save energy (fuel oil or electric quality) as 40%-50% as the total pneumatic drill. It can also work with drill rods and button bits for rock drilling.
3. Gl120y is good for blasting hole in surface mine, water electric building, road construction and stone project.
