The Rubber-Tired Gantry Crane (RTG) is an efficient container handling equipment widely used in ports and container yards. Its main structure includes the main beam, support legs, tire-based mobility system, and lifting trolley.
The main beam is the core load-bearing component of the RTG crane, with excellent rigidity and stability, capable of bearing large loads. Rails are installed on top of the main beam for the movement of the lifting trolley. The support legs are located at both ends of the main beam, providing stability to the entire structure and ensuring its stability during operation. The bottom of the support legs is equipped with large rubber tires, allowing the RTG to move flexibly within the yard and meet the needs of different workstations.
The tire-based mobility system consists of multiple drive wheels, each equipped with an independent motor and braking system to ensure smooth movement and precise positioning within the yard. The lifting trolley is located beneath the main beam and is equipped with electric or hydraulic winches for lifting and moving containers. The trolley can move laterally along the rails, allowing for precise container positioning.
The RTG crane also features an advanced electrical control system, integrating PLC (Programmable Logic Controller), sensors, and various safety protection devices. This design makes the RTG an indispensable and efficient tool for container handling in modern ports and yards.
In large port yards, the RTG crane is used to efficiently handle and stack containers, improving space utilization and operational efficiency.
The RTG gantry crane is suitable for cargo terminals, quickly responding to different operational demands and ensuring the effectiveness and safety of the cargo loading and unloading process.
In modern logistics centers, the RTG gantry crane is used to precisely manage and stack large volumes of containers, optimizing storage layout and improving overall operational efficiency.
