Abstract
A lifting column comprising two or more telescopically arranged column elements, where each column element comprises at least two column sub-elements arranged symmetrically on either side of a first vertical plane, one set of sub-column elements closer to the plane than the other set of sub-elements, where the outer sub-elements are slidingly connected to adjacent inner sub-elements by means of guiding sledges, and further where each column sub-element comprises at least two pulley wheels, one upper and one lower, and further where one first continuous flexible member runs from an upper pulley wheel of a first sub-element to a lower pulley wheel on an adjacent sub-element, so that the first flexible member runs on the upper or lower pulley wheels of the innermost sub-elements on either side of the vertical plane, and that the flexible member is shortened or lengthened by rolling at least one end of the flexible member around a drive wheel on a rotatable axle of an actuating motor. The invention also relates to a patient support table, comprising a patient support surface, a lifting column and a foundation structure for fastening said patient support table to a floor surface.
