Techniques are provided that facilitate improving operational reliability for a cantilever crane. In one example, a cantilever crane may include a mast (130), a shaft mechanism (140), and a rod (410). The mast may extend vertically from the base structure. The shaft mechanism may be disposed within the mast. The rod may be coupled to a boom arm (170) and may be disposed within the shaft mechanism. Rotation of the rod can facilitate continuous rotation of the boom arm relative to the base structure about the longitudinal axis of the rod.
本发明提供了促进提高用于悬臂起重机的操作可靠性的技术。在一个示例中,悬臂起重机可以包括桅杆(130)、轴机构(140)和杆(410)。桅杆可以从基座结构竖直地延伸。轴机构可以被布置在桅杆内。杆可以被耦接至吊杆臂(170)并且可以被设置在轴机构内。杆的旋转能够促进吊杆臂绕杆的纵向轴线相对于基座结构的连续旋转。
