Rubber tyred gantry crane

A rubber tyred gantry crane (RTG crane) (also transtainer) is a mobile gantry crane used for stacking intermodal containers within the stacking areas of a container terminal. RTGs are used at container terminals and container storage yards to straddle multiple lanes of rail/road and container storage, or when maximum storage density in the container stack is desired.[citation needed]

Being mobile, RTGs are often powered by Diesel generator systems (gensets) of 100 to 600kW. Due to the lack of an electrical grid to dump energy when containers are being lowered they often have large resistor packs to rapidly dissipate the energy of a lowering or decelerating container.[1]

Different kind of RTGs

  • The first electrified rubber-tyred gantry cranes (ERTG) in the China was unveiled by The She Kou container terminal (SCT) in Aug 2008. The new technology reduces fuel consumption by an estimated 95 percent. The new ERTG system was developed with the help of Konecranes, Conductix-Wampfler and Georgia Power. [2]
