The utility model provides an utensil take self feed back stable system's antidumping hydraulic ship lift, including setting up the ship reception chamber in the lock chamber, the initiative antidumping mechanical synchronous system that links to each other with the ship reception chamber, stabilize balanced hydraulic driving system, self feed back stable system, self feed back stable system sets up the guide rail on the lock chamber lateral wall including the symmetry, a plurality of guide pulleys that the symmetry set up on the ship reception chamber lower part and matched and connect with guide rail on the lock chamber lateral wall, and each guide pulley of its characterized in that is all fixed on the ship reception chamber through the supporting mechanism, the supporting mechanism includes the base that links to each other with the ship reception chamber, articulates the support on the base, fixes the flexible piece between support and base, and the setting sets up on the support and follows the rolling guide pulley of guide rail at the spacing fender piece in the flexible piece outside. Playing the initiative to the ship reception chamber and rectifying, after the ship reception chamber received unbalanced load, ship reception chamber appearance slope, performance ship reception chamber slope limiting displacement prevented that ship reception chamber slope volume from continuing to increase, makes hydraulic ship lift stabilize the safe and reliable operation.
