The GM range of pneumatic block-cutting machines satisfies most needs that may arise during quarry works. Thanks to its structure, the GM places itself among the medium weight machines therefore being easy and quick to use. The models are identified as:
GM1: for vertical drilling only
GM2: for horizontal drilling only
The different GM models can be equipped with 1 or 2 rock drills installed on independent and shock-absorbed mounting plates, with masts for 2,40 or 3,20 m first starting drill steels.
