The invention provides a cantilever type crane which comprises a stand column assembly and a cantilever assembly which are rotationally connected, the cantilever type crane further comprises a pulling part connected with the cantilever assembly, and when the stand column assembly and the cantilever assembly are in a folded state, the pulling part is connected with the stand column assembly and the cantilever assembly. The pulling component can pull the cantilever assembly to rotate to a preset installation position relative to the stand column assembly. By the adoption of the structure, after the cantilever type crane is transported to the offshore platform and integrally hoisted through the crane of the installation ship, the cantilever type crane can be fixed to the offshore platform through the stand column assembly in the folded state, and after the cantilever type crane and the offshore platform are fixed, the offshore platform is fixed. The cantilever assembly can be pulled by the pulling part to rotate to the preset position relative to the stand column assembly for installation, assistance of an installation ship crane is not needed, the installation efficiency is high, and the cost is low.

    本发明提供一种悬臂式吊机,包括转动连接的立柱组件和悬臂组件,所述悬臂式吊机还包括和所述悬臂组件连接的拉动部件,在所述立柱组件和所述悬臂组件处于折叠状态时,所述拉动部件能够拉动所述悬臂组件相对所述立柱组件转动至预定安装位置。采用如上结构,悬臂式吊机在运输至海上平台并通过安装船的吊机将其整体吊起后,悬臂式吊机能够在折叠状态下通过立柱组件固定于海上平台,待悬臂式吊机与海上平台固定完成,能够通过拉动部件拉动悬臂组件相对立柱组件转动至预定位置进行安装,无需安装船吊机协助,安装效率较高且成本较低。
