Marker element lifting system, abbreviated to system, comprising: - a plurality of marker elements, wherein each marker element has an upper plane having an opening therein aligned with a reinforced edge, has an element surface sloping outwardly and downwardly from the outer edge of the upper plane to a lower plane, and has a plurality of spacers, wherein the spacers project inwardly from the inner surface of the wall; wherein the marker element is designed such that a plurality of elements can be stacked on top of one another and is nested in an adjacent upper element such that at least three inner ends of the spacers on the upper element press against an outer surface of the walls of the lower element so that a separation space is created between the elements; - a marker element handling device comprising: a hollow shaft having a handle at the upper end; - an element engagement mechanism at the opposite lower end of the shaft; - a trigger in the handle connected to the engagement mechanism via the shaft; wherein the marker element handling device is designed such that an operator holding the handle can insert the element engagement mechanism through the engagement hole in a first element behind its rigid edge to engage the first element on the marker element handling device, so that the operator can operate the handle with one hand and insert the element engagement mechanism through the engagement hole in a second element behind its reinforced edge to engage the second element on the marker element handling device below the first element, and wherein the operator can manipulate the trigger to release the second element from the element engagement mechanism while the first element is held on the marker element handling device, wherein - the element engagement mechanism comprises at least two opposite levers, wherein each lever has upper and lower tabs at its outer ends, wherein the upper and lower tabs form a recess between one another, which is designed to grip the reinforced edge of an element, wherein the levers grip the reinforced edge at least opposite one another or form a stable basic shape such as triangles or circles, and - the levers are arranged to be pivotable at their inner thirds about a pivot point, wherein a preloading force is exerted on the levers at the inner end, preferably by rubber-elastic elements, so that the levers press against a conical tappet of the trigger mechanism, which is connected to the trigger in such a way that, by activating the trigger, the inner thirds of the levers are spread outwards so that the levers pivot about the pivot points and the recess at the outer end of the levers reduces its gripping diameter. - a plurality of marker elements, wherein each marker element has an upper plane having an opening therein aligned with a reinforced edge, has an element surface sloping outwardly and downwardly from the outer edge of the upper plane to a lower plane, and has a plurality of spacers, wherein the spacers project inwardly from the inner surface of the wall; wherein the marker element is designed such that a plurality of elements can be stacked on top of one another and is nested in an adjacent upper element such that at least three inner ends of the spacers on the upper element press against an outer surface of the walls of the lower element so that a separation space is created between the elements; - a marker element handling device comprising: a hollow shaft having a handle at the upper end; - an element engagement mechanism at the opposite lower end of the shaft; - a trigger in the handle connected to the engagement mechanism via the shaft;
