Conductix-Wampfler is the manufacturer of systems for the transmission of energy and data to mobile consumers. Conductix-Wampfler has been provided order by Mitsui Engineering & Shipbuilding Co. Ltd. in Japan. A total of 13 existing and four new rubber tired gantry cranes (RTGs) in Hakata Port will be equipped with the company's drive-in technology.
The order for the electrification of diesel powered RTG cranes will receive state support in the framework of a Japanese government program for CO2 reduction.
A total of 15 blocks will be equipped. The total length of power transmission segments is 3.8 km. The Conductix-Wampfler 0813 conductor rail system with 1,000 amperes and four parallel phases will be used,
Idle time and downtime of gigantic cargo handling systems in ports are cost factors for ship owners and terminal operators for many years. Next are the energy prices, which have risen continually for years.
In part, more than 50% of the total energy consumption of a port is caused by diesel powered RTGs, which are essential for cargo handling. Many operators are thus, looking for suitable power supply alternatives for this type of crane.
With the retooling to E-RTG with the so called drive-in unit by Conductix-Wampfler, the manual plugging in the RTG crane into the connection trolley of the conductor rail system can be omitted.
Instead, the connection trolley is automatically steered to the guide rails of the steel frame when the RTG crane enters the corridor, and connectors safely guided into the contact lines.
