The invention relates to the technical field of safety supporting facilities of hoist cages, and aims to provide a hydraulic balance transmission device of a construction hoist, which can keep balanced and stable hoisting of the hoist cage, guarantee the use safety of a mechanical transmission member and prolong the service life of the mechanical transmission member. The device structurally comprises the hoist cage, a hoisting transmission frame and two parallel hydraulic oil cylinders, wherein the two hydraulic oil cylinders are connected through a hydraulic oil pipe; a hydraulic oil cylinder seat, an oil cylinder seat connecting plate and a piston connecting support plate which are mutually cased are arranged on the outer side of each hydraulic oil cylinder from inside to outside in sequence; the two ends of each hydraulic oil cylinder seat and the corresponding oil cylinder seat connecting plate are movably connected with the corresponding piston connecting support plate through an oil cylinder seat connecting shaft and a piston connecting shaft respectively; each piston connecting shaft penetrates through the top of the corresponding hydraulic oil cylinder and side walls of the corresponding oil cylinder seat connecting plate and the corresponding piston connecting supporting plate; each oil cylinder seat connecting shaft penetrates through the bottom of the corresponding hydraulic oil cylinder and the side walls of the corresponding oil cylinder seat connecting plate and the corresponding piston connecting supporting plate; the top of each oil cylinder seat connecting plate is connected with a hoisting transmission frame through a connecting rod.
