The invention discloses an elevator system capable of preventing a lift car from impacting a ceiling. The elevator system comprises a shaftway, a counter-weight guide rail, a counter-weight block, a bottom plate, a lifting mechanism and a transmitting part; the counter-weight guide rail and the counter-weight block are both arranged in the shaftway, the counter-weight guide rail is arranged on the lateral wall of the shaftway, and the bottom plate is arranged under the counter-weight guide rail and connected to the lateral wall of the shaftway or arranged on a bottom bit of the shaftway; one end of the transmitting part is arranged to be opposite to the counter-weight block, and the other end of the transmitting part is arranged to be opposite to the bottom plate; and the lifting mechanism is in transmitting connection with the transmitting part, and the lifting mechanism is arranged on the lateral wall of the shaftway or the bottom plate. When the top of the lift car contacts the top of the shaftway, one end of the transmitting part abuts against the counter-weight block, and the other end of the transmitting part abuts against the bottom plate. By means of the stopping effect of the bottom plate, the counter-weight block is prevented from moving downwards continuously, and the top of the shaftway is prevented from being damaged by the lift car. The lifting mechanism acts on the transmitting part to raise the counter-weight block conveniently and quickly, and the lift car can return. Compared with the prior art, the elevator safety is greatly improved.
