A Rubber Tyred Container Gantry Crane (RTG) is a specialized type of gantry crane designed for intensive container stacking operations in container yards, rail terminals, and ports. Unlike rail-mounted gantry cranes, RTGs move on rubber tires, allowing flexible movement across container stacks and efficient use of yard space. These cranes are typically powered by diesel generators, electric motors, or hybrid systems and are equipped with advanced control systems for precise handling and high productivity.
