Abstract
A lifting column preferably, for height adjustable tables, includes a guide () and a drive unit (), the guide () including at least a first member () and a second member (), the members () being arranged mutually telescopically relative to each other. At the end of the first member () from which the second member () can be displaced sliders are arranged on an internal side thereof. At the end of the second member () extending into the first member () sliders are likewise arranged on the outside thereof. In a first plane the sliders have a first, a large, prestressing between the first member () and the second member (), while the sliders in the second plane have a second, a small, prestressing between the first () and second member (). Thus, a good dampening of vibrations of the table is achieved in case of exposure to horizontal forces.
