The utility model provides an antidumping hydraulic ship lift of area initiative antidumping mechanical synchronous system, including setting up the ship reception chamber in the lock chamber, what link to each other with the ship reception chamber stabilizes balanced hydraulic driving system, self feed back stable system, and its characterized in that still includes the initiative antidumping mechanical synchronous system that links to each other with the ship reception chamber, initiative antidumping mechanical synchronous system includes a plurality of positions many continuous steel cables with the ship reception chamber both sides, and the other end of many steel cables is walked around corresponding setting respectively and is fixed at the top of shaft at reel and setting pulley on the flotation pontoon in the shaft at top, links to each other through synchronizing shaft and shaft coupling between a plurality of reels. So that when the slope appears in the ship reception chamber, through initiative antidumping mechanical synchronous system, produce the anti overturning moment of initiative to control ship reception chamber slope volume, reduce the synchronizing shaft moment of torsion, and when ship railway carriage or compartment slope volume or synchronous?transmission moment of torsion reach the design value, correspond reel, the whole safety of guarantee ship lift through the stopper locking.
