PURPOSE: A floodgate lift for damping a falling speed is provided to damp the impact of a falling floodgate by generating repulsive force corresponding to the falling speed of the floodgate by the falling floodgate. CONSTITUTION: A floodgate lift for damping a falling speed comprises a driving member(M), a lift, and a damper(30). The driving member supplies driving force. The lift opens and closes the floodgate lifting by the driving force of the driving member. The damper is integrally connected to the lift. The damper supplies repulsive force corresponding to the falling speed of the lift to damp the falling speed of the lift. |
