Round two-stage lifting columns from the DD series

The foundation for ergonomic desks in the modern office: Thanks to their low-backlash sliding guides, the DD441.3 lifting columns ensure simple and continually reliable height adjustments of the table. The inner column profiles always move synchronously. The lifting columns are the affordable drive solution for use in stable desks. Their elegant appearance – a smooth surface without visible indentations or functional openings – enables them to be integrated into a wide variety of table frame constructions. Thus, furniture manufacturers benefit from a great deal of freedom when designing their office applications.                                                                

High-end components with outstanding functionality

The DD441.3 implements OKIN's high-end drive technology. The powerful, maintenance-free 24-volt DC motors with two Hall sensors generate a pushing force of up to 800 N. The special gearbox delivers whisper-quiet operations. The DD441.3 has a very low installation dimension of 560 mm and a standard-compliant stroke length of 650 mm – more versatility is virtually impossible. The DD441.3 is compatible with the well-established DB02, DB03 and MB02 control units, which can be programmed according to individual customer requirements. They also feature ISP intelligent system protection. The DD441.3 is perfect for constructing stable table systems according to EN 527 and BIFMA X5.5.
