An elevator braking device and an elevator system. The elevator braking device includes: a fixed frame (1); a floating bracket (2), which is disposed on the axial guide of the fixed frame (1) and movable along the axial guide; a movable plate (4) supported by the floating bracket (2), the movable plate (4) having a second friction plate (41) on a second side of the brake disc (6); an actuator (5); and a position self-adjusting member which includes a magnetic portion (31) to act on the magnetic member (211, 222) on the floating bracket (2) such that after the braking state is released, the floating bracket (2) tends to move towards a balanced position, thereby reducing a difference between a first gap (G1) between the first friction plate (25) and the brake disc (6) and a second gap (G2) between the second friction plate (41) and the brake disc (6). The elevator braking device according to the present invention ensures significant gaps between the brake disc (6) and the friction plates on both sides.
