The rigidlifting platform is provided with driving motors, and each motor individually drives a set of gear and rack mechanism; all motors are independently controlled by respective drivers, and control unitsof the drivers are in circular series connection; the synchronous vertical lifting system monitors torque values of all the motors in real time, a programmable controller is connected with all the drivers, and sensors are further connected to the programmable controller and comprise a plurality of sensor submodules; the programmable controller compares feedback pulse values of all the sensors withpulsed quantities of the corresponding drivers and send adjusting signals to ensure that the positions of the synchronous vertical lifting platform are synchronous. According to the synchronous vertical lifting system, all the drivers are in circular series connection, thus the drive synchronicity is guaranteed, and the synchronization precision is high. All the motors conduct individual drive, mechanical connection is not involved, and gear and rack mechanisms at the side positions are unlikely to get stuck.
