PLC (Programmable Logic Controller) automates and controls operations and ensures work safety. The PLC precisely manages the lifting, lowering and horizontal movement functions of the tower crane. It also monitors the load carrying capacity and improves work safety by detecting overload situations. It controls movement limits and activates emergency stops in case of danger. It is used for data acquisition and monitoring and records the operating data of the tower crane. It also supports remote control systems, allowing operators to control from a safe distance.
