The invention discloses an electromagnetic brake and an electric hoist, and relates to the technical field of electromagnetic braking equipment. The electromagnetic brake comprises a shell, an output shaft, a load limiting assembly, a brake disc and a connecting sleeve. The shell is provided with a containing cavity, and the containing cavity is located on one side of the shell in the first direction. The output shaft penetrates through the shell in the first direction. The load limiting assembly is located in the containing cavity and comprises a load limiting elastic piece and a limiting piece, and the limiting piece abuts against the load limiting elastic piece in the first direction; the brake disc abuts against the load limiting elastic piece in the first direction and is arranged on the output shaft in a sleeving mode. The connecting sleeve is arranged on the output shaft in a sleeving mode and located on the side, away from the load limiting elastic piece, of the brake disc in the first direction, the connecting sleeve is used for being connected with an external electric hoist, and a load limiting friction plate used for friction fit is further arranged between the connecting sleeve and the brake disc. By the adoption of the technology, the load limiting function of the electromagnetic brake on the electric hoist is achieved, and safety accidents caused by overweight are effectively avoided.
