The invention relates to a rack serving device ( 1 ) with a load-bearing means ( 4 ) displaceable in the height direction of a mast ( 2 ), the mast ( 2 ) being guided by means of bogie assemblies ( 7, 8 ) on bottom and top guide tracks and mounted so as to be displaceable along the guide tracks by means of a bottom and top friction-locking displacement drive ( 13, 14 ). The bottom and the top adjusting mechanisms are guided by means of height and lateral guide elements on the guide track and are designed to be displaceable relative to the guide tracks by means of a drive system ( 33 ). Arranged respectively between the displacement drives ( 13, 14 ) and bogie assemblies ( 7, 8 ) is a coupling mechanism ( 29 ), comprising at least two displaceable coupling parts ( 28 ) and, extending between the articulation axes of the coupling parts ( 28 ), at least one coupling connection ( 27 ) which is pivotable about the articulation axis substantially perpendicular to the longitudinal extension of the guide track relative to a coupling part ( 28 ) and, at an end region remote from this articulation axis, mounted so as to be slideable in a longitudinal guide extending substantially parallel with the longitudinal extension of the mast ( 2 ).
