Liebherr Container Cranes has delivered three rubber-tyred gantry (RTG) cranes to CSX Intermodal Terminals (CSXIT), aiming to deliver fuel savings of up to 40%.
Two of the machines have gone to Bedford Park in Chicago while the other one headed to Worcester, Massachusetts.
The two RTGs for Bedford Park stack six containers and truck lane wide and one-over-three containers high, featuring Liebherr’s eight rope reeving which helps to eliminate sway and skew.
A variable speed engine along with a series of gantry travel cameras and laser anti-collision systems is meant to provide the latest efficiencies and safety.
DiaMon3D, the manufacturer’s crane management and diagnostic system has been installed ensuring access to crane statistics and maintenance options in an easy to use graphical interface.
The unit for Worcester has been designed to ensure compliance with local environmental regulations governing noise and emissions.
An eight wheeler machine built around a reduced size variable speed diesel genset, supplemented by a Liebherr energy storage system for hybrid operations has been supplied.
The reduction in engine size, use of a variable speed machine and the hybrid system are meat to deliver substantially reductions in fuel consumption, emission and noise.
The crane has a safe working load (SWL) of 41 tonnes, stacks one-over-two high and serves two rail lines with their adjacent truck lanes.
Paul Bolger, head of product management with Liebherr Container Cranes, said: “The Worcester terminal can expect to see significant reductions in running costs and emissions.
“The Liebherr 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 Occupational Safety and Health Administration (OSHA) requirements in safety, noise levels and lock-out-tag-out protection.
CSXIT has previously purchased Liebherr RTGs for their Pennsylvania terminals, Pittsburgh and Chambersburg.
