Efficient gear technology contributes to high push-force capabilities and reduced noise levels. The columns incorporate a 24, 120, or 230-Vdc linear actuator to extend or retract its three telescopic aluminum profiles. Maximum operating speed, with minimal vibration, is 45 mm/sec. Stroke lengths up to 700 mm are possible. Safety features of the columns include self-lock in push and pull, integrated limit switches, cutoff switches, and a backup nut at the end position.
