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.
It is also possible to replace a drifter by a rock splitter or to choose them both. In that case they can be installed either in the separate drilling attachments that have fast coupling or they can be installed in the same drilling attachment.
In urban environment the minimizing of noise level is important. Noise level can be decreased by a silencer.
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 necessary 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 is capable of keeping the feed beam in the chosen angle and it shuts the drilling down when the chosen bore depth has been reached.
Remote control increases visibility around and in the drilling spot. It also increases work safety, because no one needs to enter the danger zone.
Spacious superstructure and many doors make service and maintenance easy.
