Strong demand for wind turbine components has prompted two German gearbox manufacturers to expand their production capacities. Bosch Rexroth, a 100% subsidiary of Robert Bosch, is investing EUR 180 million in a new works at its Nürnberg facility in southern Germany and increasing output at its existing gearbox factory in Witten, further north in the industrial Ruhr region. Bosch Rexroth expects to start production at the new factory in 2009, ramping up to full output by 2013. The company's Joachim Siedler declines to give details of factory capacity "for reasons of competition." Meanwhile, Eickhoff, based in the Ruhr region, will invest EUR 43 million in a factory to produce 500 gearboxes a year in Klipphausen near Meissen in eastern Germany. The company, which already produces 1000 gearboxes a year at its Bochum plant, expects to start production in Klipphausen in the second half of 2008.
