Steel rail synchronous intelligent group hoisting system

The utility model provides a steel rail synchronous intelligent group crane system which comprises a central control unit, a plurality of groups of field control units and a plurality of gantry cranes, and each gantry crane is provided with a detection unit; compared with the prior art, the central control unit sends the control instruction to the multiple sets of field control units, the multiple sets of field control units drive the lifting motor and the walking motor to operate according to the received control instruction, then the gantry crane is controlled to operate synchronously, automatic synchronous control is achieved, the working process is simplified, and the working efficiency is improved. A plurality of or all gantry cranes can be operated by only one worker, so that centralized hoisting and carrying operation of 100-meter long steel rails can be realized, the working efficiency is improved, and the production cost is saved; the position of the gantry crane, the lifting height and the weight of
