Liebherr Cranes Ordered in South Africa
Liebherr Africa announced the awarding of a contract for the supply of four STS and 18 RTG cranes to Transnet Port Terminals. The order will be fulfilled with the assistance of Liebherr Container Cranes in Ireland. In the last two years, Liebherr delivered nine mobile harbor cranes to Transnet, which brought their fleet to 13. In addition Liebherr Container Cranes Ltd. delivered two ship to shore container cranes to Ngqura Container Terminal in 2012. The ship to shore cranes in this order will bring the total number of Liebherr ship to shore cranes operated by Transnet Port Terminals to 31.
The new ship to shore cranes will have an outreach of 65 m, a span of 30.48 m and a back reach of 19 m. The cranes have a lift height of 41 m and will be capable of lifting a 65-metric-ton load under a twin lift spreader. These cranes have been designed to handle container vessels of up to 24 rows across, allowing the world’s largest container vessels to be serviced.
The new Liebherr RTGs destined for Ngquraare state of the art machines, will span seven containers and a truck lane and can stack up to five containers high. This is Transnet Port Terminals first purchase of Liebherr RTGs. The RTGs will be fitted with Liebherr’s DGPS, Auto Steering and Container Location Recognition systems and will interface with the TOS system providing container location and weight information.
The RTGs are fitted with numerous safety features including a whisker RTG to stack and ultrasonic RTG to RTG anti-collision systems. Cameras will be fitted to the RTGs that monitor the long travel in both directions, which are then displayed on independent monitors in the driver’s cabin.
In common with all Liebherr RTGs and RMGs, Liebherr’s eight rope reeving anti-sway system is installed as standard and effectively eliminates sway, even under the windy conditions of exposed port environments. This allows for productivity increases of between 30-40% over alternative models.
Liebherr’s dual speed drive system is installed on the RTGs allowing for significant environmental benefits including reductions in noise levels, emissions and fuel consumption.
