Here, the sensor is an upper, lower limit sensor for setting the upper and lower limits of the vehicle mount, or a height detection sensor that directly detects an imbalance of the vehicle mount or detects height information of the left and right vehicle mounts and transmits it to the controller 40, Or it may be a hydraulic sensor installed on a line for supplying hydraulic pressure to the hydraulic cylinder for lifting the vehicle mounting. For example, the height sensor may be an encoder that detects the rotation angle of the link.

As shown in FIG. 1, the fault diagnosis apparatus for a vehicle lift according to an exemplary embodiment of the present disclosure may detect a vehicle mount having reached an upper limit and a lower limit position (which may include an up and down operation). An imbalance detection for detecting the height difference between the upper limit sensor 11 and the lower limit sensor 12 and the height difference between the left and right vehicle mounting stages and the left and right vehicle mounting stages to be transmitted to the controller 40. The sensor 20 may include a hydraulic sensor 30 that detects the hydraulic pressure of the hydraulic line for supplying the hydraulic pressure to the cylinder and transmits the hydraulic pressure to the controller 40.

The controller 40 as shown in FIG. 1 receives the detection signals from the upper and lower limit sensors 11 and 12, the imbalance detection sensor 20, and the hydraulic sensor 30, and the sensors 11, 12, 20, 30. ) To monitor the normal operation.

When the lift diagnosis device 50 is electromagnetically connected to the controller 40, an abnormal sensor (or an abnormality among the upper and lower limit sensors 11 and 12, the imbalance detection sensor 20, and the hydraulic sensor 30) may be used.
