Centuries of stone dust – at a World Heritage site

Extracted material: Stone dust

Vacuum cleaner: 2 Ruwac WS 2320 H

It took over 600 years – from 1248 to 1880 – from the time the cornerstone for the Cologne Cathedral was laid to its completion. The Cathedral was named a UNESCO World Heritage site in 1996. The Dombauhütte is responsible for maintaining the building. Its 30 employees primarily work to prevent weathering of the stone building. This is always a “work in progress,” as the exterior shell requires constant care. The entire area comprises a space of 407,000 m3. Visitors can also view the workshop on the south side of the Cathedral to watch stonemasons and restoration personnel at work.

Problem

(Stone) dust is produced during almost all work carried out by the stonemason, and needs to be extracted. The Dombauhütte needed reliable, industry-strength vacuum cleaners to do so, and they needed to be able to handle fine and abrasive dust.

Solution

Two type W 2320 Ruwac AC vacuum cleaners are used daily towards the end of the work day, or when individual tasks produce a particularly large amount of dust. The vacuum cleaners handle this work reliably. In addition, the stonemasons appreciate the compact size and simple operation of the equipment, which can practically swallow hundreds of years of stone dust deposits.
