DCT Gdansk which already operates 11 Liebherr RTG’s, has taken delivery of a further three RTG’s bringing its complement to 14 units. The 16 wheeler RTGs are 1 over 4 configuration and can stack up to seven containers wide. The new RTGs will join five Liebherr STS cranes already in operation in Gdansk.
At DP World Sokhna, Egypt a second delivery of six units of 1 over 5 RTGs has increased the number of Liebherr RTGs to 11.
The Port of Cork, Ireland has recently installed a cable reeling drum Electric RTG (E-RTG) at its Ringaskiddy facility.
OJSC Petrolesport, St Petersburg, Russia has taken delivery of six RTGs of 1 over 5 configuration that can stack six containers wide. A further five units able to stack seven containers wide are due to be delivered later this year.
Pat O’Leary, Liebherr Container Cranes’ managing director said “In today’s port environment, productivity and costs are crucial. Downtime is expensive and bottlenecks on landside operations can have serious repercussions for quayside operations and overall profit. Port operators recognise that Liebherr RTGs bring multiple benefits in terms of availability, reliability, productivity and ultimately a reduction in the cost per box.”
Recent survey figures show that Liebherr has now gained significant market share and according to O’Leary this growth is projected to continue.
“During 2012 Liebherr has scheduled the delivery of several RTG projects and by year end these will have exceeded last year’s figures. Initial indications are that 2013 figures are in accordance with projections”.
Gerry Bunyan, Liebherr’s sales and marketing manager believes a number of Liebherr’s RTG key features that differentiate them from other manufacturers have helped with this growth.
“An eight rope reeving anti-sway system, which is supplied as standard on all Liebherr stacking cranes, coupled with the simultaneous operation of the gantry, hoist and travel motors allows for superior positioning of the spreader and eliminates the need for a headblock. The simplified hoist configuration optimises drive power for maximum energy reduction.
An increase in productivity of between 25% – 40% when compared with alternative designs is typical. These features combined with high availability and reliability resulting in low cost per move make the Liebherr RTG an attractive option for port operators who are serious about increasing productivity and reducing cost.”
Liebherr is continuing with their RTG development in particular regarding a new engine and drive algorithm with a view to minimising running costs.
