The invention discloses a synchronous lifting system of a car lifting unit. The synchronous lifting system comprises at least four mobile car lifting machines, wherein the mobile car lifting machines comprise machine bodies and bracket mechanisms; the bracket mechanisms comprise brackets and supporters; the brackets comprise two parallel side plates and support mechanisms for connecting the side plates; the supporters comprise two edge plates respectively arranged along the inner sides of the two side plates; and one ends of the edge plates are connected with support blocks. The synchronous lifting system further comprises a driving motor, and a PLC system capable of controlling the rotation of the driving motor; a warning device is connected to an output end of the PLC system; and proximity switches for detecting car bodies are arranged in the support blocks, and are electrically connected to an input end of the PLC system. The synchronous lifting system has such advantages as simple structure, convenience for operation, easy realization of the closed-loop control of synchronous work of the car lifting unit, facilitation of improving the synchronous precision of the car lifting unit, improvement of the system safety and improvement of the system reliability through redundant design.
