Liebherr Africa has been awarded a contract to supply a total of 22 cranes – four ship-to-shore (STS) and 18 rubber-tyred-gantry (RTG) cranes – by Transnet Port Terminals in South Africa. The order will be fulfilled with the assistance of Liebherr Container Cranes in Ireland.
Designed to handle container vessels of up to 24 rows across, allowing the world’s largest container vessels to be serviced, the new STS cranes will have an outreach of 65 m, a span of 30.48 m and a back reach of 19 m. They will have a lift height of 41 m and be capable of lifting a 65 tonne load under a twin lift spreader.
The RTGs, which will be deployed at the Ngqura Container Terminal, will span seven containers and a truck lane, stacking up to five containers high. This is Transnet’s first purchase of Liebherr RTGs.
The machines will be fitted with DGPS, auto-steering and container location recognition systems, interfacing with the terminal operating system (TOS) to provide container location and weight information. A dual speed drive system will provide significant environmental benefits, including reductions in noise levels, emissions and fuel consumption.
Safety features include a whisker RTG to stack and ultrasonic RTG-to-RTG anti-collision systems; mounted cameras will monitor the long travel in both directions that will be displayed on independent monitors in the driver’s cabin.
Installed as standard, Liebherr’s 8-rope reeving anti-sway system eliminates sway, even under the windy conditions of exposed port environments; this allows for productivity increases of between 30%-40% over alternative models.
In the last two years, Liebherr has delivered nine mobile harbour cranes to Transnet, bringing its fleet to 13. In addition the Ireland facility delivered two STS container cranes to the Ngqura Container Terminal in 2012, with this latest bringing the total number of Liebherr quay cranes operated by Transnet to 31.
