The invention belongs to the field of hoisting devices and relates to a hoisting device for a generator stator. The hoisting device for the generator stator comprises two cranes connected in parallel, at least four load bearing beams, at least four hydraulic lifting devices, a plurality of steel cables and two large hoisting poles. Each crane is provided with the bearing beams in symmetry, and the bearing beams on the two cranes are in one-to-one correspondence; the hydraulic lifting devices are arranged on the bearing beams; the hydraulic lifting devices on the same side of the two cranes are connected with the large hoisting pole on the corresponding side through the steel cables; the middle portions of the two large hoisting poles are fixedly connected with a small hoisting pole, the large hoisting poles and the small hoisting pole compose an I-shaped structure, and the lower portion of the small hoisting pole is connected with a hoisting hook. The hoisting device for the generator stator is simple in operation and high in safety and reliability, saves a traction device in a traditional hoisting frame for tracting the generator stator in position on a steam turbine platform, reduces a large quantity of mounting buffer areas reserved for existing generator stator hoisting and shortens the construction period for hoisting the generator stator.
