The invention discloses a balanced hoisting mechanism for hoisting a heavy piece. The balanced hoisting mechanism comprises two side hoisting tools and a middle hoisting tool, wherein the two side hoisting tools are connected with the heavy piece by side hoisting lug plates; the middle hoisting tool is connected with the heavy piece by a middle hoisting lug plate; each of the side hoisting tools and the middle hoisting tool comprises a hoisting tool distribution beam and a hook; a guide rail is arranged at the upper end of each hoisting tool distribution beam and is connected with a hoisting point sliding block; the upper end of each hoisting point sliding block is connected with the corresponding hook; one side of each hoisting point sliding block is connected with a hoisting tool oil cylinder; the other end of each hoisting tool oil cylinder is fixedly connected with the corresponding hoisting tool distribution beam. The balanced hoisting mechanism can be used for solving the problem that hoisting points are not uniform in stress during the hoisting of the heavy piece, and has the characteristic of being simple in structure, convenient to operate, and high in adaptability.
