    • Aspects of the present disclosure are directed to a telescopic mast. In some embodiment, the telescopic mast includes at least two telescope members with parallel walls. One of the at least two telescopic members including at least two adjoining telescopic sections, with one of the at least two adjoining telescope sections being thinner than the others of the at least two adjoining telescope sections, so that a telescope section can be passed respectively into and out of a telescope section positioned round it in a telescope member. This telescope section positioned round it can be passed into and out of a further telescope section in a further telescope member. The telescopic mast further including elastic elements/actuators fitted between the adjacent telescopic sections, the elastic elements/actuators equalize and bear the dead weight and the useful load on the telescopic mast.

    • There is disclosed a telescopic mast including one or more telescopic members with parallel walls. One of two adjacent telescoping sections is narrower than the other of the two adjacent telescoping sections such that a telescoping section can be moved into and out of, respectively, of a surrounding telescoping section in a telescopic member. This surrounding telescoping section can be moved into and out of a further telescoping section in a further telescopic member. In the one telescoping section in a telescopic member there is provided a guide rail running in axial direction of the telescoping section. Between each of two adjacent telescoping sections in a telescopic member there is provided at least one spacer means arranged for keeping the telescoping sections apart and controlling their mutual movement. This means includes a mounting fitting fastened to the second telescoping section in a telescopic member and a flexible sleeve mounted in the mounting fitting. In the flexible sleeve is fitted a slide shoe that includes a pin for engaging the flexible sleeve, and a groove arranged for engaging the guide rail.
