Prestress tensioning trolley

The utility model relates to the technical field of concrete construction, in particular to a prestress tensioning trolley. Comprising a truss, a tensioning jack and a traction mechanism, a plurality of universal wheels are arranged at the bottom of the truss, sliding tables are arranged on the two sides of the top of the truss respectively, sliding rails are arranged between the sliding tables, and the traction mechanism is in sliding connection with the sliding rails; and the tensioning jack is transversely suspended at the bottom of the traction mechanism and horizontally moves and ascends and descends under the action of the traction mechanism. According to the scheme, through the design of the sliding table and the sliding rail, when the traction mechanism suspends the tensioning jack, position regulation and control can be conducted on the jack in the up-down, left-right and front-back directions according to the tensioning position, the alignment process of the traction mechanism and the jack is greatl
