PLC control, AC frequency speed control, stable and reliable running; 5. Remote control are available according to the requirement; 6. Adequate protection devices, communication and lighting system. Single-Arm portal Crane: Single arm portal crane is mainly used in small and medium-sized port to load and unload bulk material. Light weight and small wheel pressure benefit to reduce investment and create considerable gains. It adopts rack amplitude or wire-rope amplitude (block and tackle) to accomplish variable amplitudes with load, horizontal displacement, and rotating or lifting in any degree. Cooperation of amplitudes makes the crane work smoothly and efficiently. Hooks and grabs can be equipped with it.
