The invention relates to the technical field of variable-amplitude type deck cranes, in particular to a variable-amplitude type deck crane for steel box girder construction. The technical problems that in the using process of the variable-amplitude bridge deck crane, in the hanging process of a steel box girder, due to the fact that no mechanism for adjusting, clamping and fixing the two sides and the top of the steel box girder is arranged, the steel box girder is prone to loosening, falling and the like in the transportation process, and if it encounters strong wind, the steel box girder is prone to falling off. And the steel box girder is inclined and the like. According to the technical scheme, the variable-amplitude bridge deck crane for steel box girder construction comprises a wheel type variable-amplitude crane base and a windproof protection assembly. The anti-falling clamping and hanging assembly is arranged to conduct anti-falling stable hanging on the steel box girder, so that the steel box girder cannot be loosened or fall off in the hanging process, and the steel box girder can be prevented from toppling in a strong wind environment through the windproof protection assembly; the lifting suspension assembly can be stably adjusted according to different suspension heights.

    本发明涉及变幅式桥面吊机技术领域,尤其涉及一种用于钢箱梁施工用的变幅式桥面吊机。技术问题:在变幅式桥面吊机使用的过程中,在对于钢箱梁进行吊挂的过程中,由于未设置对其两侧和顶部将进行调节夹紧固定的机构,从而导致钢箱梁在运输时容易发生松脱掉落等现象,若遇到大风天气,钢箱梁也会发生倾斜等现象的问题。技术方案:一种用于钢箱梁施工用的变幅式桥面吊机,包括有轮式变幅吊机底座和防风保护组件。本发明通过设置防脱落夹吊组件对钢箱梁进行防掉落稳定吊挂,使钢箱梁在吊挂过程中不会发生松脱掉落现象,而利用防风保护组件可以防止钢箱梁在大风环境下会发生倾倒的现象,利用升降悬吊组件可根据悬吊高度不同进行稳定调整。
