Chain lifting appliance base

A chain lifting appliance base comprises a hanging plate, a groove for containing a chain link is formed in the upper end face of the hanging plate, a first mounting base and a second mounting base are arranged on the hanging plate on the two sides of the groove in a fixed structure mode respectively and located in the middle of the hanging plate, and a pin shaft is installed between the first mounting base and the second mounting base. And the projection of the pin shaft on the hanging plate is positioned in the middle of the hanging plate, so that the unhooking condition cannot occur even if the chain shakes under the impact of external force during hoisting. Through the arrangement of the pin shaft, the hanging plate can be conveniently installed on a chain, chain links of the chain can be horizontally arranged in the grooves when a lifting appliance with a small hole diameter is hooked, the overall thickness after the chain is matched with the hanging plate is reduced, the overall strength is guaranteed,
