Due to the different sizes and heights of ships docked at the port and the rise and fall of water at the harbor, there are many problems in providing electricity to ships berthing at the port [1]. The shore power cable lifting device is adaptable to the cable connection under different environments, mainly consisting of a multi-stage telescopic hydraulic arm [2], a cable drum, a luffing mechanism, and a slewing mechanism. In the process of cable lifting, the cooperative control of multiple working mechanisms is related to the cable connection precision, as well as the safety. Compared with the traditional control of the circuit, PLC control can ensure higher accuracy and safety, and improve the automation level and convenience of shore power connection.
