Conventional Rubber Tyred Gantry cranes (RTGs) consume 2 to 2.5 liter diesel per container move. Consequently a container terminal with a throughput of 1 million TEU consumes 2 million to 2.5 million liters of diesel per year. This drives many operators to look for suitable power supply alternatives for this type of crane, in order to reduce diesel consumption and thus emissions. Conductix-Wampfler has been converting RTGs into electrified RTGs (E-RTGs) since 2006. The converting process involves shutting down the diesel genset and powering the RTG with electric power directly from the power grid. E-RTGs typically use 2.5 to 3.5 kWh electrical power per container move.
