Movable pulley shafts are inserted into the waist-shaped elongated grooves. The middle parts of the movable pulley shafts are provided with movable pulley sets. The two ends of the movable pulley shafts penetrate through the waist-shaped elongated grooves and penetrate out of holes of a connecting plate respectively to be fixed with the connecting plate via nuts. The other end of the connecting plate extends towards the direction of the pulling force oil cylinder and is fixed with a traction shaft. The traction shaft penetrates through the waist-shaped elongated grooves of the two pulley installing brackets in turn. The middle part of the traction shaft is sleeved with a traction joint which is hinged with the end part of a piston rod of the pulling force oil cylinder. The right ends of the pulley installing brackets are provided with fixed pulley sets. Steel wire ropes are wound through the fixed pulley sets and the movable pulley sets in turn so that one end is connected with the tested winching machine, and the other end is fixed on the machine frame. A pulling force load test can be conveniently performed on the winching machine by the testing stand.
