The invention provides a braking device capable of preventing an elevator car from sliding accidentally. The braking device comprises a braking mechanism, wherein the braking mechanism is arranged on an elevator counterweight mechanism, a guide mechanism and/or an elevator car pulley mechanism for applying braking force to the elevator counterweight mechanism, the guide mechanism and/or the elevator car pulley mechanism. When the loading capacity of an elevator traction mechanism is maintained by utilizing the braking device provided by the invention, the elevator car can be effectively prevented from sliding accidentally; moreover, reasonable elevator wellhole spatial layout and relatively low construction cost are also taken into account.
