An actively controllable suspension arrangement (9) for an elevator system (1) and an elevator system (1) provided therewith are proposed. The elevator system (1) comprises an elevator car (3) being suspended by suspension traction means (5) in a load direction (51) such as to be displaceable within an elevator shaft (4) upon controlled displacement of the suspension traction means (5). The elevator system (1) further comprises drive means (7) for controlled displacing of the suspension traction means (5) upon control by an elevator control (65). The suspension arrangement (9) also comprises a carrier assembly (33) comprising at least one fixator (41) for attaching the suspension traction means (5) to the carrier assembly (33). Furthermore, the suspension arrangement (9) comprises a displacement assembly (35) adapted and mechanically connected to the carrier assembly (33) such as to induce displacing of the carrier assembly (33) against the load direction (51). Additionally, the suspension arrangement (9) comprises a position determination assembly (37) adapted for determining measurement signals indicating a real position of the elevator car (3) within the elevator shaft (4). Finally, the suspension arrangement (9) comprises a controller (39) for controlling operation of the displacement assembly (35), the controller (39) being adapted for controlling the displacement assembly (35) based on the measurement signals from the position determination assembly (37).
