(Description of how to use)

  Next, a method of use and effects of the vehicle lift device of the present invention will be described.

  In order to start the lift operation, the vehicle lift device is turned on. The elevating body 3 is located at the lower end (lower limit) as shown in FIG.

  Next, the vehicle is advanced to a lift-up position in the vehicle lift device, and each of the support arms 4 is rotated and extended to lift up the bottom of the vehicle by the vehicle receiving portion 4a at its tip. Position it below the point.

  Then, while checking whether the vehicle receiving part 4a matches the lift-up point by visual inspection or the like, the operator keeps pushing the raising button 7a of the operation switch part 7 to raise the support arm 4 If the worker determines that the vehicle receiving part 4a matches the lift-up point, the user continues pressing the up button 7a to support the vehicle in the vehicle receiving part 4a, and the vehicle Raise

  When the worker determines that the vehicle receiving part 4a does not coincide with the lift up point, the operator releases the raising button 7a, and if necessary, pushes the lowering button 7b to lower the support arm 4 After that, the position of the vehicle receiving portion 4a is adjusted, and then, the lift button 7a is pressed again to make the vehicle receiving portion 4a coincide with the lift-up point, and when it is determined to coincide with it, When the lift button 7a is kept pressed to support the vehicle on the vehicle receiving portion 4a to raise the vehicle and it is determined that the vehicle does not match, the adjustment is performed again.

  Note that there is a possibility that a plurality of the raising button 7a and the lowering button 7b may be pressed in the work of aligning the vehicle receiving portion 4a with the lift-up point of the vehicle, but as described later Since it does not ascend to the position detected by, it is not counted as the number of lift usages.

  After the vehicle receiver 4a matches the lift-up point and lifts the vehicle, the lift button 7a is continuously pressed and, as shown in FIG. 3, the vehicle has a desired height, for example, from the ground When rising to a height of 300 mm, the proximity switch detects that it approaches the proximity body 6a, the detection signal is received by the elevation restricting portion 5b, and the elevation restricting portion 5b drives the elevation. The unit 5a controls the elevating body 3 to stop so that the elevating body 3 is stopped at that height.

  Therefore, safety can be enhanced because the vehicle and the lift device for the vehicle and the vicinity thereof can be confirmed before the vehicle rises to a certain extent.

  Further, the maintenance time management unit 5c receives the detection signal, and adds up the stored actual number of times of use at the time of rise and stores it.

  Then, if the safety confirmation can be confirmed, the lift button is kept pressed again to raise the vehicle to a position where it can be subjected to maintenance and inspection.

  After completion of the maintenance, the lowering button 7b is kept pressed to lower the vehicle.

  Then, when the support arm descends to a desired position, for example, when the vehicle descends to a height of 300 mm, the proximity switch detects that it approaches the proximity body 6a, and the elevation restriction portion 5b detects the detection signal. The elevator control unit 5b controls the elevator drive unit 5a to stop the elevator body 3 so that the elevator body 3 stops at that height.

  Therefore, before lowering the vehicle to the ground, the safety can be enhanced because the vehicle, the vehicle lift device and the vicinity thereof can be confirmed once.

  Further, the maintenance time management unit 5c receives the detection signal, adds one to the already stored number of actual use at the time of fall, and stores it.

  Then, after the safety is confirmed, the lowering button 7b is kept pressed to lower the vehicle to the lower end to land on the ground, and then the vehicle is withdrawn.

  And, when carrying out a lift operation in the next vehicle, the maintenance timing management unit 5c adds 1 to the already stored number of times of use of the lift every time it is detected by the detection device as described above. Do.

  Then, the maintenance timing management unit 5c regards the stored actual use number at the time of rising or the actual use number at the time of falling as the actual number of times of lift use, and causes the display unit to display it, or The number of half of the total of the actual number of times of actual use is regarded as the actual number of times of use of the lift, and is displayed on the display unit 8.

  In addition, the actual number of times of use of the lift is set to a desired set number of times for maintenance determined to be required for maintenance of the vehicle lift device stored in advance by a maintenance time determination unit provided in the maintenance time management device 5c. When it becomes, the display 8 is made to display that effect.

  Further, when the actual number of times of use of the lift approaches the number for maintenance by a desired amount, that effect is displayed on the display device.
