The Straddle Carrier (also known as Container Straddle Carrier) is a high-efficiency container handling and stacking solution purpose-built for ports, terminals, rail hubs, and large-scale logistics facilities. Featuring a portal frame structure that straddles containers or transport vehicles, it utilizes a hydraulic lifting system and container spreader to autonomously pick up, transport, stack, load, and unload containers. Combining horizontal transport and stacking functions without the need for fixed rails, the Straddle Carrier delivers exceptional maneuverability and operational flexibility, significantly improving quay-to-yard transfer efficiency. It is a core asset in modern automated container terminal operations.
