Stone Scorpion


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

The equipment applies perfectly for bolting and vertical or horizontal drilling at construction sites, drill & blast bench, trenching, bench in tunnels, mines and stone quarries throughout all seasons.

It is capable of operating with high precision in small spaces due to it compact size, powerful rock drill, 350° turning superstructure and remote control. It is capable of operating underground as well. Suitable for drill rod size is R32 / R38/ T38.

It is possible to replace a drifter by a rock splitter. If there is need for both of them, it is possible to install them both to the same drilling attachment or install them in separate drilling attachments using fast coupling.

Equipped with Montabert drifters HC50 (14Kw output power)

There is also a possibility to build Stone Scopion to be a railbound crawler drill.

Versatile equipment, it is possible to replace the drifter with a rock splitter or to choose them both for a Drill & Split solution.

Suitable for urban environment thanks to noise shield protection, that can minimize the operating noise level.
