When sourcing a used container crane (such as a STS, RTG, or RMG), you must prioritize the Lifting Capacity (Safe Working Load) under spreader and the Outreach/Backreach distances to ensure compatibility with your vessel sizes. Critically examine the Hoisting, Trolley, and Gantry speeds, as these directly impact your terminal's TEU throughput. Additionally, verify the Power Supply requirements (Voltage/Frequency) and the Control System version (e.g., Siemens or ABB) to ensure it can be integrated with your existing terminal operating system.
