A short elongated housing forms the base of the actuator and includes an electrical gear drive and storage magazine for the spindle segments. The drive spins a helically grooved wheel that engages the similarly grooved inside face of the spindle segments. As the wheel spins it simultaneously pull

forms a telescoping tubular column, or spindle, from linked segments resembling curved parallelograms. The telescoping linear actuator has a lifting capacity up to 200 kg (~440 pounds) for a travel of 400 mm (~15.75 inches).

the segments from their horizontal arrangement in the magazine and stacks them along the vertical path of a helix into a rigid tubular column. The reverse process lowers the column.
