The invention relates to the technical field of tower cranes, and particularly discloses a jacking cross beam anti-falling device which comprises an anti-falling plate, the anti-falling plate is rotationally connected to a jacking cross beam body and comprises a connecting section and an abutting section which are fixedly connected with each other, the connecting section is rotationally connected with the jacking cross beam body, and a torsional spring is arranged between the connecting section and the jacking cross beam body; the abutting section can abut against the bottom face of the step. The scheme is used for solving the problems that potential safety hazards exist on a tower crane without an anti-falling structure in the prior art, and the tower crane with the anti-falling structure is tedious in operation and easy to fail in falling prevention.
本发明涉及塔式起重机技术领域,具体公开了顶升横梁防脱装置,包括防脱板,所述防脱板转动连接在顶升横梁本体上,防脱板包括互相固定连接的连接段和抵接段,连接段与顶升横梁本体转动连接,连接段与顶升横梁本体之间设有扭簧,抵接段能够与踏步底面相抵。本方案用以解决现有技术中未带防脱结构的塔式起重机上存在的安全隐患的问题、带有防脱结构的塔式起重机上存在的操作繁琐和防脱容易失效的问题。
