    Abstract: An elevator braking device and an elevator system are provided by the present disclosure. The elevator braking device includes: a fixed frame; a floating bracket, which is disposed on the axial guide of the fixed frame and movable along the axial guide; a movable plate supported by the floating bracket, the movable plate having a second friction plate on a second side of the brake disc; an actuator; and a position self-adjusting member which includes a magnetic portion to act on the magnetic member on the floating bracket such that after the braking state is released, the floating bracket tends to move towards a balanced position, thereby reducing a difference between a first gap G1 between the first friction plate and the brake disc and a second gap G2 between the second friction plate and the brake disc.

    Abstract: An elevator car including: a door; and an apron movable between a deployed position and a retracted position; wherein in the deployed position the apron hangs below the door; wherein in the retracted position the apron is vertically overlapped with the door; and wherein in the retracted position the apron is engaged with the door such that it is movable sideways together with the door. As the apron is displaced upwards relative to the elevator car it will block the doorway. However, as the apron is engaged with the door in the retracted position, opening the door also moves the apron out of the way of the doorway so that the apron does not hinder passengers from using the elevator car.
