The invention provides a ring chain electric elevator. The ring chain electric elevator comprises a chain, a left wall plate, a right wall plate, an upper lifting hook, a motor, a planetary speed reducing mechanism, a gear driven mechanism and a chain driving mechanism; the planetary speed reducing mechanism comprises a machine seat, a machine shell, a machine cover, an input gear, an input shaft, an output shaft and a planetary gear set; the input gear sleeves the input shaft and synchronously rotates with the input shaft; the planetary gear set comprises a fixed gear ring, a movable gear disc, a mounting plate with a center hole and at least three planetary gears; the fixed gear ring is fixed on the machine shell; a circle of inner teeth are arranged on the inner side of the fixed gear ring and are meshed with the planetary gears; the planetary gears are rotationally connected to the mounting plate; the planetary gears are uniformly distributed in the circumferential direction by taking the center hole as the circle center; one end of the input shaft is provided with a driving spline, and the driving spline penetrates through the center hole to be meshed with the planetary gears; and the output shaft is connected with the movable gear disc and synchronously rotates with the movable gear disc. The planetary gear set is arranged, so that efficient transmission is achieved, the torque is greatly increased, the load capacity is high, and the transmission power loss is effectively reduced.
