By relocating its lattice girder slab production from the Wachenroth site to the Rattelsdorf site some 45 km away, Röckelein is able to make the work processes for this product segment considerably more economical. The Rattelsdorf site, where products for underground construction, concrete blocks, chimneys and ready-mix concrete have mainly been produced until now, also has its own gravel pit, from which all of the aggregates for its own production are obtained. Whereas the raw materials previously had to be driven by truck into the Wachenroth works, the aggregate silos are now filled directly from the gravel pit with its sorting and crushing units. In order to realise the state-of-the-art lattice girder slab plant at the Rattelsdorf site, Röckelein erected a new twin-aisle production building with a total floor area of 7,200 m². After a short dry-run phase the first lattice girder slab was produced on 17 August 2012 and already met the company’s high quality requirements. The lattice girder slabs are manufactured on a pallet circulation plant from Ebawe Anlagentechnik GmbH with extensive automation technology. Major parts of the circulation plant are the modern systems for reinforcement processing and placement from Progress Maschinen & Automation AG, an affiliated company of Ebawe. In addition to processing stations for the longitudinal and transverse reinforcement, this modern circulation plant is characterised by the integration of a lattice girder welding machine, which is new on the market from Progress. For the supply of high-quality concrete the Liebherr company erected an impressing mixing tower, which stands directly adjacent to the new building.
