Accelerating DX and Dramatically Improving Sustainability at the Port of Tokyo: Introduction of the First Remote-Controlled RTGs
The Port of Tokyo introduces its first remote-controlled Rubber Tired Gantry (RTG) cranes to promote improved working environments, operational efficiency, and decarbonization.
The Port of Tokyo has been undergoing redevelopment of the Aomi Public Wharf since 2023, and a portion of the area is now set to open. In conjunction with this opening, the operator of the Aomi Public Wharf will introduce and begin operating the first remote-controlled RTGs* at the Port of Tokyo.
This initiative contributes significantly to the realization of a sustainable Port of Tokyo by ensuring a comfortable and safe working environment. The Tokyo Metropolitan Government and the national government are providing financial support for a portion of the costs associated with introducing this cargo-handling equipment.
* RTG stands for "Rubber Tired Gantry Crane," a large portal crane used for transporting containers within a container yard.
1. Purpose of Introduction
(1) Ensuring a comfortable and safe working environment
Previously, operators controlled the machinery from the driver's seat on the equipment itself. With the introduction of these new machines, operations can be conducted from an office, significantly improving the working environment.
(2) Improving terminal operation efficiency
Efficiency in terminal operations will be enhanced by promoting DX, such as linking remote-controlled cargo handling with container pickup and delivery reservation systems.
(3) Promoting decarbonization
These machines are designed to be convertible to fuel cell (FC) power sources. Once converted, they will utilize hydrogen energy to promote the decarbonization of the Port of Tokyo.
