The invention provides a foldable flat-top tower crane boom superlift stability augmentation device which is used for a flat-top tower crane and comprises a superlift support, a steel wire inhaul cable, a superlift winch, a foldable support supporting rod, a support pull rod and a force transducer. The superlift support is hinged to the support base and fixedly connected to a truss of the rotation part. The superlift winch and the winch bracket are fixedly connected to the front end of the arm frame; the steel wire inhaul cable is connected with the front end of the superlift bracket and the superlift winch; the support supporting rod is hinged to the rear side of the support base and fixedly connected with the superlift support. The support pull rods are fixedly connected to the inner sides of the super-lift supports on the two sides of the arm support. The superlift stability augmentation device is arranged on the two sides of the arm frame of the flat-top tower crane, the stability of the arm frame under various working conditions can be improved by increasing the rigidity of the arm frame in the horizontal and vertical directions, and the working stability of the flat-top tower crane is improved.

    本发明提出了一种可折叠式的平头塔机臂架超起超起增稳装置,该装置用于平头塔式起重机,包括超起支架、钢丝拉索、超起卷扬、折叠式支架撑杆、支架拉杆以及测力传感器;其中,所述超起支架与支架底座铰接并固接与回转部分的桁架上;所述超起卷扬与卷扬支架固接与臂架前端;所述钢丝拉索连接超起支架前端与超起卷扬;所述支架撑杆铰接与支架底座后侧并与超起支架固接;所述支架拉杆固接与臂架两侧超起支架内侧。本发明的超起增稳装置设置在平头塔机的臂架两侧,通过增加臂架水平和垂直方向的刚度,能够增加臂架在各种工况下的稳定性,提高了平头塔机的工作稳定性。
