The invention discloses an elevator car balance compensation chain system which comprises an elevator car, an auxiliary grooved pulley, a main cable, a pulley, counterweights, a secondary cable, a connector, a common stopper, a compensation chain and a compensation chain accommodating groove, wherein the main cable is wound around the auxiliary grooved pulley and used for suspending the elevator car; the main cable suspended from the edge of the auxiliary grooved pulley is wound around the pulley; the counterweights are suspended from the pulley via a rope; the secondary cable is used for suspending the elevator car; the connector is used for connecting the main cable and the secondary cable; the common stopper is fixed to the connector and used for limiting the connector from moving; the compensation chain is suspended on the counterweights, and the length of the compensation chain is equal to the length of the moving distance of the counterweights; the compensation chain accommodating groove is used for accommodating the compensation chain; and the compensation chain is made of carbon fiber composite material coated with a sizing agent. The carbon fiber composite material enhances the strength of the compensation chain, and avoids the phenomenon that the outer layer of the compensation chain is rubbed excessively so as to flake off and cause abnormal noise in an elevator.
