In an anchor system, for example, an undercut anchor system, having an anchor bolt with an expansion element, preferably at least one engagement means for the purpose of bearing a load, an expansion sleeve surrounding the anchor bolt, a means for detecting an axial end position of the expansion sleeve on the expansion element when the expansion sleeve is expanded and moved axially, the axial end position of the expansion sleeve should be able to be detected precisely. This problem is solved in that the means has a sensor for the purpose of detecting the axial end position. |
