摘要

The lifting aggregate has a telescopic column consisting of an inner pipe (2) and an outer pipe (3), where an energy storage device, particularly a gas pressure spring is arranged in the column. The inner pipe is fixed relative to the outer pipe over a braking device by an actuating device. Another column is formed with an outer pipe and a round pipe (4) surrounding the outer pipe.
