Liebherr to supply ten electric RTGs to Montreal

Montreal Gateway Terminal Partnership (MGT) has ordered ten electric rubber-tyred gantry (ERTG) cranes from Liebherr Container Cranes.

The units will be delivered to both the Cast and Racine Terminals in 2019.

In 2016, a conductor bar system was installed at the terminal, and associated electrical and mechanical works retrofitted to two of the earlier delivered Liebherr RTGs to allow for full electric operation.

Based on the experience with the ERTGs, MGT has contracted Liebherr to deliver a further 10 ERTGs.

According to the manufacturer, the electrically operated units will offer reduced noise and emissions, while MGT CEO Michael Fratianni noted that fuel consumption should drop by as much as 95%.

Gerry Bunyan, sales and marketing manager at Liebherr Container Cranes, said: “The substantial savings which result from running on electricity offer a quick return on investment, whilst the reduced maintenance costs and the high availability and productivity allow MGT to offer a premium service to their customers while benefiting from exceptionally low entire lifetime costs.”

Since Liebherr supplied its first crane to Cast Terminal in 1997, MGT has procured four ship-to-shore (STS) cranes and eight RTGs from Liebherr.

The conductor bar connection is the Conductix Wampfler drive in L system, which includes the ProfiDat data transfer medium, hoping to allow for accurate transmission of high data volumes in real-time between the RTGs and the terminal operating system.

The machines are also fitted with a diesel generator allowing for operational flexibility and for travel between stacks.

The cranes, which have a safe working load of 40.6 tonnes, can handle six containers plus a truck lane wide whist stacking one over five high.

The cranes feature Liebherr’s purpose built Liduro heavy-duty crane drive system.

LED lighting is used throughout which together with other energy saving technology, reduces electricity consumption.

Productivity and safety aids including DGPS, automatic  gantry steering and anti-collision systems are included.
