The invention discloses an electric lifter with an abutting device. The lifter comprises a shell and a rope wheel, a mounting cavity used for mounting the rope wheel is formed in the shell, a rope inlet and a rope outlet are formed at the position, above the rope wheel, of the shell, and a rope penetrates through the rope inlet and the rope outlet and is tightly wound around a rope groove of the rope wheel; a speed reduction device is arranged in the shell, the output end of the speed reduction device is connected with the rope wheel, and a power input shaft is arranged at the input end of the speed reduction device; and a speed-limiting brake device is arranged on the power input shaft. Compared with the prior art, the electric lifter has the advantages that the speed-limiting brake device is arranged, so that the speed can be automatically limited when the rotating speed of the rope wheel is too high, and the use safety of the electric lifter is improved.
