The invention relates to the technical field of cranes, and discloses a super-lifting device and a crane, the super-lifting device comprises at least one super-lifting unit, each super-lifting unit comprises a mast assembly arranged on a cargo boom in a swinging mode, and the mast assembly is provided with a super-lifting winch used for winding a traction rope; the guide assembly is arranged on the cargo boom, and the guide assembly is located on the side, close to the tail of the cargo boom, of the mast assembly; the connecting assembly is provided with a first connecting part and a second connecting part, the mast assembly and the guide assembly are fixedly connected through the connecting assembly, the situation that the mast assembly and the guide assembly jump along with traveling of a crane can be effectively avoided, when the super-lifting device in the form is stored, a traction rope does not need to be completely taken back, and the operation is convenient. When the superlift device is used, storage can be completed only by separating the end of the traction rope from the head of the cargo boom and fixing the end of the traction rope and the head of the cargo boom at the preset storage position, the process that the traction rope is completely taken back and installed again is omitted, and the use difficulty of the superlift device is greatly reduced.
本发明涉及起重机技术领域,公开了超起装置及起重机,超起装置包括至少一个超起单元,每个超起单元包括:桅杆组件,可摆动的设置于起重臂,桅杆组件上设有用于卷绕牵引绳的超起卷扬;导向组件,设置于起重臂,导向组件位于桅杆组件的靠近起重臂的尾部的一侧;连接组件,具有第一连接部和第二连接部,本发明通过连接组件将桅杆组件和导向组件固定连接,能够有效避免桅杆组件和导向组件随着起重机行驶而产生跳动,此种形式的超起装置进行收纳时,无需再将牵引绳彻底收回,只需要将牵引绳的端部与起重臂的头部分离并固定在预设的收纳位置便能够完成收纳,免去了牵引绳完全收回与再次安装的过程,大大降低了超起装置的使用难度。
