The invention provides a telescopic superlift device which comprises a fixed arm, a telescopic arm, a driving mechanism and a control system, the fixed arm is connected to a suspension arm of a crane through a tail structure of the superlift device, the driving mechanism is fixedly connected to the middle section of the fixed arm, the fixed arm is provided with a containing cavity, and the containing cavity is arranged in the length direction of the fixed arm; the telescopic arm is arranged in the containing cavity and connected to the driving mechanism, the driving mechanism can drive the telescopic arm to stretch out and draw back in the containing cavity, and the control system calculates the length needing to be adjusted according to the lifting operation requirement and controls the driving mechanism to drive the telescopic arm to stretch out or draw back so as to complete length adjustment. The superlift device can solve the problem that in the prior art, the length of a superlift device cannot be adjusted in the erecting state, cost is saved, and transportation is convenient. The invention also relates to a crane.

    本发明提供一种伸缩式超起装置,包括固定臂、伸缩臂、驱动机构和控制系统,固定臂通过超起装置的尾部结构连接于起重机的吊臂,驱动机构固定连接于固定臂的中段,固定臂设有容置腔,容置腔沿固定臂的长度方向设置,伸缩臂设置在容置腔内,伸缩臂连接于驱动机构,驱动机构可驱使伸缩臂在容置腔内伸缩,控制系统根据起重作业需求运算所需调整的长度,控制驱动机构驱使伸缩臂伸出或者缩回以完成长度调节。本发明的超起装置能够解决现有技术中的超起装置在起竖状态下无法调节其长度的问题,并节约成本,便于运输。本发明还涉及一种起重机。
