Stone Scorpion – for demanding work environments and tasks

Stone Scorpion crawler drill is an excellent solution for stepped excavation, bolting or natural stone quarries. Its superior advantages include compact size, wide reach and coverage, 350° turning superstructure, and rough terrain capabilities.

The equipment suits excellently to bolting and vertical or horizontal drilling at construction sites, canals, tunnels, mines, and stone quarries through all seasons. It can be used for drilling holes for explosives in excavation or blasting. It can operate with high precision in small spaces because of its small size, powerful rock drill, 350° turning superstructure and remote controllability. It is capable of operating underground as well.
