The invention discloses a hanging type electric chain hoist which comprises a lifting chain, a fixing plate and a hoist body fixed to the fixing plate, one end of the lifting chain is fixedly connected to the fixing plate, the other end of the lifting chain is connected to the hoist body, a lifting hook assembly is hung on the lifting chain, and a limiting stopper assembly is fixedly connected to the position, on the connecting side of the fixing plate, of the lifting chain. A counter weight sleeve capable of moving up and down relative to the lifting chain is sleeved on the lifting chain below the limiting stopper assembly, the limiting stopper assembly comprises a stop block assembly clamped on the lifting chain and a counter weight balance rod group rotatably connected to the stop block assembly, and a counter weight limiting switch is arranged below the counter weight balance rod group. And a steel wire rope is connected between the counter weight balance rod group and the counter weight sleeve. According to the limiting device, the heavy hammer type limiting is adopted as the first section of limiting, the push plate type limiting is adopted as the second section of limiting, different protection modes can be combined, meanwhile, the limiting device is arranged to be of a separable structure, and it is guaranteed that when the lifting hook reaches the limiting position, safety is guaranteed while the lifting hook is limited.
本发明公开了一种吊挂式环链电动葫芦,包括吊链、固定板和固定在所述固定板上的葫芦主体,吊链的一端固定连接在所述固定板上,另一端连接至葫芦主体,吊链上挂装有吊钩组件,固定板连接侧的吊链上固定连接有限位器组件,限位器组件下方的吊链上套装有可相对其上下移动的重锤套,限位器组件包括卡装在吊链上的止动块组件、可转动连接在所述止动块组件上的重锤平衡杆组,重锤平衡杆组下方设置有重锤限位开关,所述重锤平衡杆组与所述重锤套之间连接有钢丝绳。采用重锤式限位为第一段限位,推板式限位为第二段限位,可以组合不同的保护模式,同时将限位器设置成可分离的结构,保证在吊钩达到极限位置时,在对吊钩限位的同时保证了安全性。
