The invention discloses a synchronous lifting system of a car lifting unit based on a pressure sensor. The synchronous lifting system comprises at least four movable car lifting machines, wherein the car lifting machine comprises a machine body and a support frame mechanism; the support frame mechanism comprises a support frame and a support head; the support frame comprises two lateral boards parallel to each other and a support mechanism used for connecting the lateral boards; the support head comprises two side boards which are arranged along the inner sides of the two lateral boards respectively; one end of each side board is connected with a support block; the synchronous lifting system also comprises a driving motor and a PLC system capable of controlling the driving motor to rotate; the output end of the PLC system is connected with an alarm device; a pressure sensor is arranged in each support block and is electrically connected to the input end of the PLC system. The synchronous lifting system of the car lifting unit based on the pressure sensor has the advantages that the structure is simple, the operation is convenient, the closed-loop control of the synchronous operation of the car lifting unit is liable to implement, the synchronous precision of the car lifting unit is improved, the safety of the system is improved, the redundancy design is adopted, and the reliability of the system is improved.
