A self-climbing tower crane includes a crane base configured to be placed on a support at a hoisting site, tower segments to erect a crane tower, a crane tower lifting unit mounted on the crane base, and a slewable jib unit. The tower crane is configured to, with the slewable jib unit connected to an upper tower segment, erect the crane tower by stacking tower segments onto one another from below to lengthen the crane tower under the slewable jib unit. The crane tower includes an upper section to be composed of a series of multiple upper tower segments and a lower section to be composed of a series of multiple lower tower segments. Each upper tower segment is embodied as a tubular girder type tower segment. Each lower tower segment is embodied as a latticed structure type tower segment. The tower crane further includes an upper stabilizer device and a lower stabilizer device, each configured to horizontally connect the upper section of the crane tower to an external tall structure, e.g. a wind turbine mast.
