Epiroc helps demolish school in southern Germany

It was the first time Ottl Abbruch & Rückbau used Epiroc’s CC 3700 cutter tool

The 1970s buildings, which was comprised of a reinforced concrete skeleton with masonry infill, was demolished to make way for a new building. OA&R undertook the works over a period of nine months, during which time they selectively demolished over 27,000 cubic metres (953,000 cu ft) of material.

Due to the school’s residential location, low-noise and vibration equipment was needed to complete the project. According to Epiroc, this prompted OA&R to use the CC 3700 cutter. It was the first time the company had used the model and Herbert Schiefer, the technical manager at OA&R, said: “That was exactly the right decision. The concrete had no chance against the CC 3700”.

While the company used a Hitachi ZX800 long-front excavator with an Epiroc CC 3700 cutter attachment to take down the 18 m (59 ft) high main school building, the flat roof of the school’s gymnasium required the use of different equipment.

OA&R, which used a range of Epiroc attachments including multi grapples and hydraulic breakers on the project, dismantled the gymnasium with an Epiroc CC 2500 combi cutter mounted on a tracked Hitachi ZX300 excavator and a Cat 336 excavator with a CC 3300 cutter.
