QTG20-3065 2T topkit tower crane with best system and inner climbing system

    Inner climbing tower crane has three attached frames, from down to up respectively are load bearing attached frame, antirotation attached frame and transition attached frame. The distance between two adjacent attached frames is nine to twelve meters, three attached frames all are on the girder Steel, and they connect with the girder Steel by bolts. The girder Steel is put on the concrete beam of core tube elevator hoistway, and they connect with each other by bolts to assure that connection of girder steel and building structure is reliable. All attached frames can be dismantled to assure the cycle use and function conversion. 

    Load bearing attached frame is mainly to bear the vertical-down acting force generating in every kind of working condition. Antirotation attached frame is mainly to bear the torsional moment and bending moment generating in every kind of working condition, and serve as the climbing pathway in the process of climbing and at last it serves as antirotation attached frame. Tower crane only uses load bearing attached frame and antirotation attached frame to fix tower body in normal working condition, but before climbing we need to install the third attached frame to serve as transition attached frame, so as to assure the reliability of climbing track. Climbing height is the distance between load bearing attached frame and antirotation attached frame.
