The invention discloses a lifting device for a counterforce-type roller braking check-out bench, and the device consists of a square steel frame, limiting guide rails, hydraulic cylinder assemblies, and shaft weight sensors. The shaft weight sensors are disposed on the square frame at two ends of the counterforce-type roller braking check-out bench, and the square steel frame is fixed on the limiting guide rails, wherein the limiting guide rails are inclined from the horizontal plane. One end of each hydraulic cylinder assembly is connected with one side surface of the square steel frame. The counterforce-type roller braking check-out bench, supported by the square steel frame, is driven by the hydraulic cylinder assemblies to translate up and down along the limiting guide rails. The device employs the hydraulic cylinder assemblies to adjust the height of the counterforce-type roller braking check-out bench, thereby adjusting the height of a tested wheel, and enabling the tested wheel to be located at the same horizontal height with a non-test wheel. The device can improve the accuracy of the detection of vehicle braking performance.
