A device for actuating anti-rolling securing bars 23, 24 on tailgates has a double-acting pivot cylinder 41 which is operated with a compressible medium such as air or oil with wind chambers on the feed lines 68, 69, 76, 77. The change-over valve 74 can be moved into the unloading position at any desired time causing the securing bar 23, 24, which rests in a securing fashion against the wheel of a rolling container located on the tailgate, to be initially merely prestressed in its pivoted-in position. The pivoting in and releasing of the secured wheel is subsequently triggered by the rolling container briefly rolling back. Thus, it is then no longer necessary to actuate the change-over valve at the same time as the rolling back of the rolling container so that operation is made easier. Accordingly, the change-over valve does not have to be constructed as foot-operated switch either so that obstructions of this kind on the loading platform can be dispensed with. <IMAGE>
