The invention relates to an automatic carrier (1) for loads which are displaced, in particular for pipelines and the like, having a fastening part (2), a loadbearing part (3) and a spring system (4) which is arranged between the fastening part (2) and the loadbearing part (3) for generating a carrying force (T) which remains constant over a carrying travel of the loadbearing part with respect to the fastening part, wherein the spring system (4) has a suspension system (5) which absorbs the load, a compensation apparatus (6) for compensating for changing spring forces of the suspension system (5) over the carrying travel (t), and a prestressing apparatus (7) for setting a prestressing force (V) of the suspension system (5). With the aim of making uncomplicated adaptation or change possible of the suspension system (5) to a change in the prestressing force (V) of the suspension system (5), it is proposed to provide a correction apparatus (13) for correcting deviations in the carrying force (T) over the carrying travel (t) as a consequence of a changed prestressing spring force (V).
