Device for testing rollover-prevention performance of cab

The utility model discloses a device for testing the rollover-prevention performance of a cab, which comprises a load cylinder. The mounting end of the load cylinder is connected with a sliding plate on an upright post. The piston rod of the load cylinder is connected with a load sensor. The load sensor is connected with a load distributor. The load cylinder is hung onto a supporting plate on the upright post to be kept at a horizontal posture through an elastic hanging ring. The device also comprises a hydraulic control station. The hydraulic control station is connected with the load cylinder through a high-pressure oil pipe. The device is low in cost and adopts an assembly structure, thus can be detached from the field after the testing process. Therefore, no production space in a workshop is occupied. The stroke and the installation height of the load cylinder are adjustable. The test is high in both precision and safety performance. During the loading process, the direction of the loading force is automa
