Clearing the Way For a Luxury Hotel
Based on Atlas Copco and Brokk technology one of the most demanding reconstruction projects in Stockholm's history will be completed in time - and flawless accuracy. Two famous mills of the Saltsjoqvarn area, the Red Mill (1889) and the Semolina Mill (1920) are converted into luxury apartments and a prestigious hotel. This project however demands maximum care during planning and construction - for the building shells have to remain unaltered, due to their historical value. Starting in June 2007, the Rivners AB company accepted the challenge to gut the mills completely - and carefully. One of the most delicate tasks had been the demolishing of the giant cereal's silos of a 25 x 15 x 30 m dimension.
The Brokk is remote controlled. The operator gets precise control of the machine while staying at a safe distance of projections or falling debris. The new luxury hotel will celebrate its grand opening in September 2009.

Another demanding procedure: the demolishing of the roof. Section by
section the roof's parts were lifted down by a crane with a lifting capacity
of 14 t. Once the roof had been carried away, the floors were next to be
battered down. Hugh beams were hewn away while supporting concrete beams
had to be lifted down from about 20 m. Again, joined precision equipment
turned out to be the key to project completion, with regard to the rigid
safety regulations that were given: the Brokk 90, equipped with an Atlas
Copco SB 150 hydraulic breaker. Thanks to its slim body and notable low
weight (transportable with a common construction elevator), it appeared
unproblematic for the operator to pilot the Brokk 90 securely through all
the narrow limited spaces inside of the mill.
