The invention relates to a tower crane, preferably a rotary tower crane, particularly preferably a top-slewing crane, comprising a jib and a counter-jib. The jib and/or counter-jib is hinged to the tower top and/or rotating platform by means of at least one connection point. A first connection part of the at least one connection point has a concave stop surface, and a second connection part of the connection point comprises a convex counter-stop surface, wherein the counter-stop surface of the second connection part acts on the stop surface of the first connection part by means of a pressure force in order to produce a force-fitting connection between the connection parts.
