Description of Post-Tension Hydraulic Lifting Jack The prestressed tensioning jack specializes in special tensioning jacks for tensioning steel strands and other prestressed tendons. It generally needs to be used in conjunction with the tensioning oil pump, and the power for tensioning and returning to the top is provided by the high-pressure oil of the tensioning oil pump. According to the different structures, it is divided into front card tensioning jack and through-center
