[0002] Generally, prestressed tendons are arranged inside the cantilever capping beam. After the capping beam concrete project is completed, the threading and tensioning of prestress need to be carried out. Conventional short pier columns can use a lift truck to complete this operation. However, for the tensioning operation of large cantilever capping beams with a construction height greater than 20m, if a floor-type lift truck is still selected to assist in the operation, in order to increase the stability of the operating vehicle, the base should be appropriately increased. Even if the base is large enough, the stability of the lifting operation platform drops sharply with the increase of the operating height, and safety is difficult to guarantee. It is easily restricted by the height of the pier column during the construction process and has poor stability. Therefore, it is necessary to set up a prestressed tensioning operation platform that can solve the above problems. Content of the Utility Model
