Heavy multi-platform linkage synchronous lifting system

A heavy multi-platform linkage synchronous lifting system can solve the problem that an existing hydraulic lifting platform cannot be used for lifting petroleum pipes with different lengths and has the risks of sliding down and safety. The lifting device comprises lifting devices and driving devices, the driving devices provide power for the lifting devices, the number of the lifting devices is N,and N is a natural number larger than N; the lifting device comprises a table top used for bearing materials and further comprises a jacking mechanism driving the table top to move up and down, and the table top is arranged at the top of the jacking mechanism. The N jacking mechanisms are connected through a linkage device, and the linkage device is connected with the driving device. The liftingdevice can bear heavy load, can keep good synchronism when a plurality of sets of lifting tables work synchronously, and is particularly suitable for transportation of special petroleum pipes. 一种重型多平台联动同步举升系统，可解决现有的液压升降台不能满足用于
