The invention relates to a tailgate with a foot-operated safety circuit (3), which can be operated by two-foot operation, for raising and lowering the platform (1) which is borne by a lifting mechanism (2). Here, the foot-operated safety circuit (3) has four switches (4, 5, 6, 7) which are arranged in series, two (4, 6) of which are provided for ''raising'' and two (5, 7) of which are provided for ''lowering''. Each current branch of the series circuit is assigned two break-contact elements and two make-contact elements in such a way that at least one switch (4, 6; 5, 7) assigned to a function (raising or lowering) to be switched closes its function circuit and opens the opposite circuit (for lowering or raising). <IMAGE>
