The new RTGs feature high capacity and performance with low maintenance and user-friendly operation, according to Noell. Their one over five stacking capability enables high-capacity stacking in the container yard. Operational performance is optimised through design features such as a fully electric trolley system with high-efficiency electric winches. These are supported by a differential global positioning system operating in conjunction with a local area network.
Ease of maintenance is a major feature in the overall design, and is enhanced through remote crane monitoring from the terminal workshop. As part of the maintenance reduction effort, Noell Crane Services worked closely with MICT in the training of maintenance staff. The staff were involved in the final phases of the erection and commissioning of the four RTGs, and also received intensive training from Siemens on the cranes’ AC vector control drives and PLC systems, and from Cummins on electronic engine programming, monitoring and troubleshooting.
The acquisition of the RTGs not only signals an upgrade of the current reachstacker-based landside handling system at the terminal but also the deployment of container handling technology that represents a first in Madagascar, according to ICTSI.
