Vehicle supporting machine

The utility model discloses a vehicle supporting machine, which comprises a support, a lift platform capable of vertically sliding along the support, and a lift driving device for driving the lift platform. The lift driving device includes a motor and a transmission component, a limiter is disposed on the support, and the limiter is serially connected with the motor through a contactor. When in use, the lift platform descends to the limiter and ejects off the limiter, and the limiter acts on the contactor to disconnect a contact of the contactor from power so as to control power off and rotation stoppage of the motor, thereby realizing accurate control of the lift platform, effectively guaranteeing equipment and personal safety and ensuring smooth running of maintenance work.
