description The invention provides a liftable constant-force hanger test board which comprises a base and a portal frame, the portal frame is fixed to the upper end of the base, slideways are formed in the middles of the left end and the right end of the portal frame, a cross beam is slidably connected between the interiors of the slideways, a test mechanism is installed in the cross beam, and an electric hoist is fixedly installed at the upper end of the portal frame. The lower portion of the electric hoist is connected with the upper portion of the beam. The electric hoist is arranged to hoist the cross beam, so that the cross beam can be conveniently lifted, the hydraulic oil cylinder is driven to lift, then all piston rods are inserted into the first positioning hole and the second positioning hole through the oil conveying pipeline to limit the cross beam, and the defects that an original hydraulic oil cylinder is installed on the cross beam, cannot lift and is low in efficiency are overcome. The variable-force spri
