The invention discloses an ultra-large tower crane, which comprises a flat-top tower crane (100) with a horizontal cargo boom (1) and a movable arm tower crane (200) arranged above the top of the flat-top tower crane, the movable arm tower crane comprises a movable arm (8) capable of luffing in a pitching manner, and the movable arm and the horizontal cargo boom can horizontally rotate independently of each other. According to the ultra-large type tower crane, on the basis of a flat-head tower crane, particularly, the movable arm tower crane is additionally arranged on the top of the tower crane, the two cranes are combined and can flexibly and independently work, and the movable arm tower crane is small in size, high in flexibility and high in practicability. The movable arm tower crane can effectively overcome the defects of insufficient operation space and the like caused by the fact that a flat-head tower crane is easy to interfere with surrounding buildings, and the movable arm tower crane is used as an independent crane, is flexible in operation, is larger in hoisting weight, and is particularly suitable for disassembly and assembly operation of self parts and surrounding parts of the tower crane and maintenance operation of the tower crane.
本发明公开了一种超大型塔式起重机,包括具有水平起重臂(1)的平头塔式起重机(100)和安装在平头塔式起重机的顶部上方的动臂塔式起重机(200),动臂塔式起重机包括能够俯仰变幅的动臂(8),动臂和水平起重臂能够彼此独立地水平回转。本发明的超大型塔式起重机在平头塔式起重机的基础上,特别地在塔机顶部增设动臂塔式起重机,双机组合且能够各自灵活地相互独立作业,动臂塔式起重机的尺寸小、灵活性强,可有效弥补平头塔式起重机易与周边建筑产生的干涉带来的作业空间不足等缺陷,而且动臂塔式起重机作为独立起重机,作业灵活的同时,起吊重量更大,尤其适于塔机的自身部件和周边部件的拆装作业和塔机自身的维护作业。
