The invention provides a sling chain shackle. The sling chain shackle is widely applicable to the industry of sewage treatment for lifting of equipment like an underwater pump dragged by a lifting sling chain and can conveniently and rapidly draw and place underwater equipment when cooperatively used with a crane. The sling chain shackle provided by the invention overcomes a plurality of disadvantages like that a gate should be closed to stop water, a well should be evacuated and a worker has to go down into the well to hang a suspension hook when underwater equipment is to be maintained, thereby improving work efficiency, reducing production cost and effectively avoiding safety accidents. The sling chain shackle is composed of an upper part and a lower part; pins are arranged between the upper part and the lower part for connection of the upper part and the lower part (thereby facilitating dismounting of the sling chain shackle); the upper part is a lifting lug part which is connected with the crane; the lower part is a lifting buckle part which is connected with the sling chain during operation; and the lower part is provided with a special sling chain guide groove, a slope inclination angle and a back unidirectional roller, so the lower part is conveniently and reliably buckled and hanged on the sling chain, thereby allowing the underwater equipment to be drawn out.
