Stone spider - Intended by the manufacturer
Stone spider crawler drill is an excellent solution for stepped excavation, bolting or natural stone quarries.
Stone spider is the biggest of all the Stonepower crawler drills. It maybe the biggest in Stonepower family but in comparison with other similar products it is very compact. A 12.5 ton crawler drill with tracks and 350° turning superstructure is capable to drill also in tight drilling targets.
The first Spider has a Montabert HC109 rock drill, which makes it possible to bore 51-89 mm boreholes. It is possible to choose between several rock drill manufacturers and types/models.
Turning superstructure is a key factor in increasing the work efficiency. There is a considerable less need to move the crawler thanks to turnability of the superstructure and wide boom coverage. But when it is is necassary to move, tracks, oscillation and a good stability make it safe to move the drilling rig.
It is also easy to move the crawler drill further to another construction site, because its transportation height is only 3 m.
Spider has 6-cylinder engine with 175 kw power. Cummins has successfully put a lot of effort in fulfilling the newest environmental standards.
Stone spider has an automatic feed angle adjusting system and bore depth control. The system shuts the drilling down when the chosen bore depth has been reached. The system is capable of keeping the feed beam in the chosen angle with a precision of 0.2°.
Remote control increases visibility around and in the drilling spot. It also increases work safety, because no one needs to enter the danger zone.
Spider has HAWE hydraulics as all the other Stonepower drilling rigs.
Spacious superstructure and many doors make service and maintenance easy.
