An elevator car sliding prevention system comprises a tensioning assembly and a first safety clamp assembly. The tensioning assembly comprises a speed limiter, a speed limiter tensioning wheel and speed limiting steel wire ropes. The first safety clamp assembly comprises a first device body, electromagnets, clamping springs, movable clamp blocks and fixed clamp blocks. The electromagnets are arranged in the first device body. The movable clamp blocks are arranged on the electromagnets. The fixed clamp blocks and the movable clamp blocks are oppositely arranged and can clasp the speed limiting steel wire ropes under the action of the clamping springs. The elevator car sliding prevention system can assist in stopping an elevator and solve the problem of car sliding of an elevator car. An elevator system comprises the elevator car sliding prevention system, a traction machine, the elevator car, a band-type brake, a control cabinet and an electric assembly. The elevator car sliding prevention system comprises the tensioning assembly and the first safety clamp assembly. The electromagnets are electrically connected with the electric assembly. The band-type brake is in signal and electrical connection with the electric assembly. The elevator car sliding prevention system can prevent car sliding when the elevator car moves abnormally.
