Lifting pillar for patient beds of other industrial applications

摘要

The pillar includes at least one lifting cylinder (10a,20a,23a) designed as a hydraulic cylinder for at least vertical lifting (VH) and with at least one guide (8a,14a) assigned to at least one lifting cylinder for a guide in the direction of lift of the lifting cylinder. The guide is formed from two interlocking profile sections (51,52,53,54) passing inside each other like a telescope. Each of the sections specified as a tubular profile section with a cross-section differing from circular and with its axis in the direction of lift (VH), that at least one lifting cylinder is accommodated inside the profile sections. Guide pieces (55) are provided on at least one of the two profile sections formed on the guide, which work together with the outer surface of the relevant other profile sections and are adjustable in an axial direction perpendicular to this outer surface. A swivelling support (4,a) or upper lifting pillar connections (64) are used for such a support.
