The invention relates to the technical field of hoisting machinery, in particular to a superlift device, a cargo boom assembly and hoisting machine.The superlift device comprises a middle mast assembly and two lateral mast assemblies, the first end of the middle mast assembly is installed on a basic boom, and the second end of the middle mast assembly is connected with a tail boom section in a boom section through a steel wire rope; the two lateral mast assemblies are arranged on the two opposite sides of the middle mast assembly respectively, the first ends of the lateral mast assemblies are connected with the basic arm, and the second ends of the lateral mast assemblies are connected with the tail arm through steel wire ropes. The first ends of the three mast assemblies are connected to the basic boom, the second ends of the three mast assemblies are connected to the tail boom section in the boom section through steel wire ropes, the two lateral mast assemblies can solve the sidewise bending problem of the cargo boom, the middle mast assembly can improve the deflection problem of the cargo boom, and then multi-dimensional reinforcement of the cargo boom is achieved. And the stability and the hoisting capacity of the cargo boom are improved.

    本发明涉及起重机械技术领域,特别是涉及一种超起装置、起重臂组件以及起重机械,超起装置包括中间桅杆组件和两个侧向桅杆组件,中间桅杆组件的第一端安装于基本臂,中间桅杆组件的第二端通过钢丝绳与臂节中的末节臂连接;两个侧向桅杆组件分别设置于中间桅杆组件相对的两侧,侧向桅杆组件的第一端与基本臂连接,侧向桅杆组件的第二端通过钢丝绳与末节臂连接。三个桅杆组件的第一端连接于基本臂,第二端通过钢丝绳连接于臂节中的末节臂,两个侧向桅杆组件可以解决起重臂的旁弯问题,中间桅杆组件可以改善起重臂的挠度问题,进而实现起重臂的多维度加强,提高了起重臂的稳定性和吊载能力。
