摘要

Vertical elongate support (2) for supporting a parked vehicle trailer (1), consisting of a top prop tube (21), an inner prop member (22) which can telescopically slide into the prop tube (21), and a threaded spindle (3) for moving the inner prop member (22) in relation to the prop tube (21), whereby the threaded spindle (3) meshes with a threaded bearing (31) that is secured to the upper end of the inner prop member (22). The upper end of the threaded spindle (3) is connected to a crown wheel (32), the upward-facing surface of which is part of a thrust bearing (33) or is designed to accommodate a thrust bearing (33). The thrust bearing (33) supports the vehicle trailer (1), either directly or via a cover (23) that is connected to the prop tube (21).
