The invention relates to the technical field of cranes, in particular to a port gantry crane which comprises a top seat and a supporting arm. The mounting frame is mounted at the bottom of the top seat; the winding roller is rotationally mounted in an inner cavity of the mounting frame; the first motor is mounted on one side wall of the mounting frame; the steel wire rope is connected to the roller wall of the winding roller in a winding manner; the bottom end of the steel wire rope penetrates through the mounting frame, when the lifting hook drives goods to rise, gravity can be generated through the goods, the top plate can be driven to move downwards, the vertical rod drives the U-shaped plate to move inwards through the connecting plate to be arranged on the outer side of the lifting hook in a sleeving mode, the lifting hook can be limited, and deflection of the lifting hook is prevented. According to the lifting hook, the situation that goods rotate in the lifting process can be effectively avoided, and the problem that in the background technology, a lifting hook drives the goods to rotate easily in the lifting process, and large potential safety hazards exist is solved.

    本发明涉及起重机技术领域,具体为一种港口龙门起重机,包括顶座、支撑臂;还包括:安装框,所述安装框安装于所述顶座的底部;卷辊,所述卷辊转动安装于所述安装框的内腔;第一电机,所述第一电机安装于所述安装框的一侧壁上;钢丝绳,所述钢丝绳缠绕连接在所述卷辊的辊壁上;所述钢丝绳的底端贯穿所述安装框,当吊钩带动货物升起时会通过货物产生重力,可实现带动顶板向下运动,竖杆通过连板带动U形板向内侧运动套设在吊钩的外侧,可实现对吊钩进行限位,防止其偏转,可有效的避免货物升起过程中发生转动的情况,以解决上述背景技术中提出的吊钩带动货物升起过程中容易转动起来,存在较大安全隐患的问题。
