The invention discloses a balance hoisting device for a powerhouse roof parapet wall and relates to a hoisting device. The balance hoisting device for the powerhouse roof parapet wall comprises a lifting hoist, a pulley block, a lifting support arm, anti-side-turning balance arms, clamping arms, an overturn-preventing balance arm and a balancing weight. The lifting support arm is fixed to the powerhouse roof parapet wall through the clamping arms under the lifting support arm, and the lifting hoist with the pulley block is disposed in the front of the lifting support arm so that the lifting hoist can conveniently move back and forth along the lifting support arm. In order to prevent overturning and side turning during lifting, the tail end of the lifting support arm is connected with the overturn-preventing balance arm, and the balancing weight is additionally disposed at the tail of the overturn-preventing balance arm; meanwhile, the anti-side-turning balance arms which are horizontally perpendicular to the direction of the support arm are disposed in the position that the lifting support arm makes contact with the top of the parapet wall, so that the stability of the lifting operation is improved. The balance hoisting device for the powerhouse roof parapet wall is simple in structure, easy to disassemble and assemble, low in cost and easy and convenient to operate, the transferring is convenient, materials are easy to obtain, the device is particularly suitable for construction parts where hoisting machines cannot be adopted, the construction speed can be effectively increased, and the cost is reduced.
