The RTGs, two for Bedford Park, Chicago, Illinois and one for Worcester, Massachusetts have entered service in the past two months delivering fuel savings of up to 40%.
The two RTGs for Bedford Park stack six containers and truck lane wide and one over three containers high. The cranes feature Liebherr's eight rope reeving which eliminates sway and skew. A variable speed engine along with a series of gantry travel cameras and laser anti-collision systems contribute to safety and efficiency. DiaMon3D, the company's crane management and diagnostic system, has been installed, providing access to crane statistics and maintenance options via a graphical interface.
In Worcester, Liebherr had to account for local environmental regulations govern noise and emissions. An eight wheeler machine built around a reduced size variable speed diesel genset, supplemented by an energy storage system for hybrid operations has been supplied. The implemented solutions result in reduced fuel consumption, emissions and noise. The crane has a SWL of 41 tonnes, stacks one over two high and serves two rail lines with their adjacent truck lanes.
Three other CSXIT terminals, located in Pennsylvania, Pittsburgh and Chambersburg, are also equipped with Liebherr RTGs.
