Already since the 1980ies, Otto Nussbaum GmbH & Co. KG has been using welding robots of Carl Cloos Schweisstechnik GmbH. On the occasion of the 75th company anniversary the manufacturer of lifting platforms, situated in Kehl, Baden-Württemberg, modernised its production comprehensively. The QR-CC-4.1 QIROX compact cells have a 2-station workpiece positioner with vertical change and vertical rotation. With a clamping length of up to 1,250 mm and a maximum load of 250 kg per side a wide range of components can be processed in the system. The systems are equipped with the new QRH-280 QIROX welding robot which was particularly developed for the CLOOS compact cell solutions. The compact cells and systems offer a maximum production flexibility as the modular design makes it possible to add individual enhancements and upgrades at any time.
