Conductix-Wampfler offers fully electric RTGs

German energy and data transmission supplier Conductix-Wampfler has announced that it is now offering port operators and crane manufacturers a full E-RTG system, which enables the fully electric operation of rubber-tyred gantry cranes (RTGs).

The new system, which is already operational at the Port of Tanjung Pelepas in Malaysia, enables cranes to travel up to 1,500 m on power from the energy-storage system thanks to the use of a new lithium-ion battery and optimised charging technologies, which ensure that diesel fuel will no longer be necessary.

While the port cranes were previously up to 90% electrically driven with the remaining 10% requiring diesel fuel when changing blocks or alleys, the new battery technology permits the electrical energy supply for RTGs even in those situations.
