RTGs will remain the primary machines for moving containers in terminal yards worldwide.
RTGs represent more than 50% of the total fuel consumption at a typical port.
Conventional rubber-tired gantry cranes (RTGs) are equipped with diesel gensets that transform diesel fuel into electrical energy. This energy powers the electric motors that are necessary for the movement and positioning of containers in the port.
Electrification of the RTG
Converting a conventional RTG into a fully electric RTG (E-RTGTM) means shutting down the diesel genset and powering the RTG with electric power directly from the power grid. The E-RTGTM conversion can be accomplished with one of two different unique electric power supply systems developed by Conductix-Wampfler: Motor Driven Cable Reel System or Conductor Rail System.
E-RTGTM : A Crucial Contribution to Fuel Savings and Clean Ports!
Low energy costs and minimal environmental impact are key concerns of modern port logistics. With the consumption of many liters of diesel fuel per day and rising diesel fuel prices, powering of RTGs represents a substantial cost factor for port operators.
The conversion of diesel to electric powered RTGs results in a reduction in diesel fuel consumption of about 95%. The remaining diesel engines are only used to transfer the RTG from one container lane to another or from the container lane to the maintenance area. During normal operation they remain switched off, which drastically reduces the emission of greenhouse gases such as CO2 or NOx into the port environment.
Conductix-Wampfler’s core competency is in the development, production, consulting, and installation of tailor made, engineered solutions that provide energy supply and data transmission for our customers‘ moving machinery.
If you seek a turnkey solution to add the “E“ to your RTG, look no further than Conductix-Wampfler – we have the answers!
