A self-climbing tower crane (600) includes a crane base (610, 612) configured to be placed on a support (2) at a hoisting site, a tower section (700) erecting the crane tower (600), a crane tower lifting unit (50, 650) mounted on the crane base (610, 612), and a rotatable cantilever unit (670, 70). The tower crane (600) is configured to erect the crane tower (600) by stacking the tower sections (700) one on top of the other from below with the rotatable cantilever unit (670, 70) connected to the upper tower section (750, 90) to lengthen the crane tower (600) below the rotatable cantilever unit (670, 70). The crane tower (600) includes an upper section (700, 800) comprised of a series of a plurality of upper tower segments (750) and a lower section (800) comprised of a series of a plurality of lower tower segments (850). Each upper tower section (750, 90) is embodied as a tubular beam-type tower section (90, 91). Each lower tower section (850) is embodied as a tower section (90, 91) of the lattice structure (671, 673) type. The tower crane (600) further comprises an upper stabilizer arrangement and a lower stabilizer arrangement, each stabilizer arrangement being configured to horizontally connect an upper section (700, 800) of the crane tower (600) to an external higher structure (671, 673), such as a wind turbine tower (201).

    一种自爬升塔式起重机(600),包括配置成在吊升现场放置在支撑物(2)上的起重机底座(610,612)、架设起重机塔(600)的塔段(700)、安装在起重机底座(610,612)上的起重机塔提升单元(50,650)以及可回转悬臂单元(670,70)。塔式起重机(600)配置成,在可回转悬臂单元(670,70)连接到上部塔段(750,90)的情况下,通过从下方将塔段(700)彼此堆叠来架设起重机塔(600),以在可回转悬臂单元(670,70)下方加长起重机塔(600)。起重机塔(600)包括由一系列多个上部塔段(750)构成的上部区段(700,800)和由一系列多个下部塔段(850)构成的下部区段(800)。每个上部塔段(750,90)体现为管状梁型塔段(90,91)。每个下部塔段(850)体现为格构结构(671,673)型塔段(90,91)。塔式起重机(600)进一步包括上部稳定器装置和下部稳定器装置,每个稳定器装置均配置成将起重机塔(600)的上部区段(700,800)水平地连接到外部较高结构(671,673),例如风力涡轮机塔架(201)。
