Rockster's impact crusher R900 on a great construction site in Austria’s skiing region Hochkönig, building a new storage reservoir for snow machines

The Rockster R900 was part of a recently completed project of the company G. Hinteregger & Sons Construction Company Ltd. from Salzburg. They were commissioned from mid-June to mid-October to build a storage reservoir with about 70,000 m³ capacity and a pumping station, to supply water to the numerous snow machines during the ski season.

The jobsite was located 1,600 m above sea level and all of the rock excavation material was recovered from greywacke shale, crushed with the R900 and reused for different areas on the site. For crushing the virgin stone, the company Hinteregger hired a Rockster impact crusher R900 from Rockster’s Austrian distributor Haberl Construction Ltd in Seekirchen. The R900 crushed material from 0 - 700 mm in diameter and produced gravel 0/32 and 32/70. 0/8-material was separated by another screen and used for rock slopes below the drainage mats, the grain size 8/32 was used for drainage and the grain size 32/70 was required to overfill the lining foil.

R900 easily crushed 8,000 m³ of hard rock

In total, about 8,000 m³ of rock material was crushed at this alpine site. Project Manager of the company Hinteregger, Johann Lienbacher reports: "We had hired a Rockster crusher for the first time and the performance exceeded our expectations. I would especially highlight the easy delivery and removal as well as the simple operation of the R900."
