Crane Electrification Systems

The RTGs equipped with a diesel-electric-drive are used in harbours all over the world. By means of these RTGs trucks and so-called “prime movers” are loaded resp. unloaded with the containers of the container ships. Continuously increasing fuel costs, the required time for refuelling oft he cranes, increased maintenance costs for the diesel-electric-drives with the corresponding downtimes as well as tightened environmental regulations led tot he requirements of the crane manufacturers and port operators to as far as possible replace the standard drive by a flexible power transmission.
