Description

StoneSpider NT2 is a two-boom crawler drill allowing new drilling possibilities thanks to its fully turnable (360°) superstructure and booms that work independently from each other.

StoneSpider NT2 is extremely suitable for open quarry mining, bolting, canal excavation and natural stone quarries. The hydraulics of the crawler drill is dimensioned in such a way that the working rotation speed is only 1 650 rpm, allowing considerable savings in the fuel consumption.

A one-boom version is also available.
