The invention belongs to the technical field of hoisting equipment, and discloses a cantilever crane which comprises a stand column, a rotating cross beam, a rotating driving assembly and a clamping assembly. The rotating cross beam is vertically connected to the stand column and can rotate around the stand column; the rotating driving assembly comprises a floating tensioning connecting piece, a rotating chain, a rotating chain wheel and a rotating driving piece, the rotating driving piece is arranged on the rotating cross beam and connected with the rotating chain wheel, the rotating driving piece is configured to drive the rotating chain wheel to rotate, the first end of the rotating chain is fixed to the stand column, and the second end of the rotating chain bypasses the rotating chain wheel; the rotating chain is arranged on the stand column and connected with a floating tensioning connecting piece arranged on the stand column, and the floating tensioning connecting piece can provide pulling force for the rotating chain to enable the rotating chain to be tensioned. The clamping assembly is arranged on the rotating cross beam in a lifting mode through the lifting driving assembly. The cantilever crane is high in rotation precision.

    本发明属于吊装设备技术领域,公开了一种悬臂吊,包括立柱、旋转横梁、旋转驱动组件和夹持组件;旋转横梁垂直连接于立柱并能够以立柱为轴转动;旋转驱动组件包括浮动涨紧连接件、旋转链条、旋转链轮和旋转驱动件,旋转驱动件设置于旋转横梁上并与旋转链轮连接,旋转驱动件被配置为驱动旋转链轮转动,旋转链条的第一端固定在立柱上,旋转链条的第二端绕过旋转链轮,并与设置在立柱上的浮动涨紧连接件连接,浮动涨紧连接件能够向旋转链条提供拉力,使旋转链条保持涨紧;夹持组件通过升降驱动组件可升降地设置于旋转横梁上,上述悬臂吊的回转精度高。
