A swivel unit of a height-adjustable support for trailers or the like

The present invention proposes a swivel unit (10) for a height-adjustable support of vehicles such as trailers, semi-trailers or the like, comprises a base unit (15) having a base plate (29) for resting on an underlying surface, at least two compensating elements (13a, 13b) which are rollable on the base plate (29), having coaxial openings (19) in which a support tube (12) is rotatably engaged for a pivotable support of the swivel unit (10). Said swivel unit (10) further comprises at least one arc-shaped reinforcement member (20a, 20b) for attachment to said compensating element (13a, 13b) between a longitudinal axis of the support tube and the base plate (29), such that stiffness of the swivel unit (10) is increased.
