Liebherr Container Cranes Ltd recently delivered three RTGs to CSX Intermodal Terminals (CSXIT) in the USA
The RTGs, two for Bedford Park, Chicago (IL) and one, featuring hybrid drive, for Worcester (MA), entered service in the past two months and are said to delivering fuel savings of up to 40%.
The Bedford Park machines stack 6 + 1/1 over 3 and feature Liebherr’s 8-rope reeving designed to eliminate sway and skew and enhance productivity. A variable speed engine along with a series of gantry travel cameras and laser anti-collision systems provide the latest efficiencies and safety. DiaMon3D, Liebherr’s advanced crane management and diagnostic system has been installed ensuring access to crane statistics and maintenance options in an easy to use graphical interface.
In Worcester, local environmental regulations govern noise and emissions. The 8-wheeler RTG supplied is built around a reduced size variable speed diesel genset, supplemented by a Liebherr energy storage system for hybrid operations. Substantially reduced fuel consumption, emissions and noise are the major benefits from the reduction in engine size, use of variable speed engine and hybrid system. The crane has a SWL of 41 tonnes, stacks 1 over 2 and serves two rail lines with their adjacent truck lanes.
Paul Bolger, Liebherr Container Cranes’ head of product management, said: “The Worcester terminal can expect to see significant reductions in running costs and emissions. The energy storage system alone reduces fuel consumption and emissions per hoist cycle by as much as 40%. When compared to an RTG with a larger engine, the environmental benefits and savings are substantial.”
The RTGs for both terminals have been designed to meet or exceed the OSHA (Occupational Safety and Health Administration) requirements in safety, noise levels and lock-out-tag-out protection. CSXIT previously purchased Liebherr RTGs for two Pennsylvania terminals, Pittsburgh and Chambersburg.
