The invention discloses a super-lifting device. The super-lifting device comprises a super-lifting fixed end and a super-lifting telescopic end; the connecting modes of the super-lifting fixed end andthe super-lifting telescopic end comprise that the super-lifting fixed end and the super-lifting telescopic end through a telescopic mechanism or a lengthened section, and the super-lifting fixed endand the super-lifting telescopic end through a rotary connecting part. A crane comprises a lifting arm, a vehicle frame chassis and a rotary table; the rotary table is arranged at the end part of thevehicle frame chassis; the lifting arm is connected to the rotary table; and the super-lifting device is connected to the lifting arm. According to the super-lifting device, a length adjusting methodis implemented, the working length of the super-lifting device is increased in the situation of limited overall crane layout space, and the rigidity of a boom system is improved, so that the liftingperformance of the crane can be greatly improved.

    本发明公开了一种超起装置,包括超起固定端和超起伸缩端;所述超起固定端与超起伸缩端连接方式包含:所述超起固定端与超起伸缩端通过伸缩机构或加长节连接;所述超起固定端与超起伸缩端通过旋转连接部连接;一种起重机,所述起重机包括吊臂、车架底盘、和转台,所述转台设置在车架底盘端部,所述吊臂与转台连接,所述超起装置与吊臂连接。本发明实现长度调节的方法,在起重机整车布局空间有限的情况下增大超起装置的工作长度,提升臂架系统的刚度,从而能够极大程度的提升起重机的吊装性能。
