The invention relates to the technical field of cranes, and discloses an overload limiter device for a bridge crane, the overload limiter device comprises a mounting plate, the top of the mounting plate is fixedly connected with a motor, the top of the mounting plate is fixedly connected with two supporting seats, and the interiors of the two supporting seats are rotatably connected with wire rollers; a pull rope is wound on the outer surface of the wire roller, and the bottom of the pull rope is fixedly connected with a shell. According to the overload limiter device for the bridge crane, an object is hung on a hook, a motor is started to drive a wire roller to drive a pull rope to take up, the pull rope is pulled upwards to drive a shell to move upwards, when the weight of the object exceeds the limit, the hook can drive a movable plate to move downwards, and meanwhile a first sliding block stretches a first spring; a second sliding block stretches a second spring, a movable plate extrudes a third spring, the movable plate moves downwards to drive a pressing block to press a switch downwards, the switch is started to drive an alarm to start to give an alarm, and therefore the effect of rapidly reminding an operator of overweight can be achieved.
本发明涉及起重机技术领域,且公开了一种用于桥式起重机的超载限制器装置,包括安装板,所述安装板顶部固定连接有电机,所述安装板顶部固定连接有数量为两个的支撑座,两个所述支撑座内部转动连接有线辊,所述线辊外表面缠绕有拉绳,所述拉绳底部固定连接有外壳。该用于桥式起重机的超载限制器装置,物体挂在挂钩上,通过启动电机带动线辊带动拉绳进行收线,拉绳向上拉动带动外壳向上移动,当物体的重量超过限制时,挂钩会带动活动板向下移动,同时第一滑块拉伸第一弹簧,第二滑块拉伸第二弹簧,活动板挤压第三弹簧,活动板向下移动带动压块向下压动开关器,开关器启动带动报警器启动进行报警,从而能带动快速提示操作人员超重的效果。
