DTH Rock Drilling Rig

GL120 Full Pneumatic Drilling Rig

GL120 Full Pneumatic Drilling Rig


The above picture is the rig with full pneumatic configurations, and it can realize small diameter hole drilling under low air pressure. It can be used for presplitting blast, slope anchor, road construction, etc.


The above picture is with down the hole hammer and bits configurations for blasting hole in surface mine, water electric building, road construction and stone project, etc.

1. It is a full motorized rig with strong grade ability, convenient to move and turn around, and can be operated in short distance temporary traction, with theses advantages, the rig can adapt to complicated working conditions.

2. The maintenance workload for the rig is small and needs little time to do the auxiliary work. The pneumatic spare parts are with high temperature resistance, low failure rate and easy to repair and maintain.
3. The spare parts of GL120 rig is widely used and easy to get all over the world.

4. The GL120 rig can be equipped with three kinds of rotation motor device (vane pneumatic motor, gear pneumatic motor, 5.5kw or 7.5kw electric motor rotation), we can customize according to customer’s need. With different configurations, the rig can realize different working ways as a pneumatic rock drilling rig or a blasthole drilling rig. Details are as below.
