Liebherr's 200-tonne electric machine headed for China

It is also the world’s largest electrically- operated Liebherr port handling machine with gantry undercarriage as well as the largest port handling machine Liebherr has ever produced. The machine was handed over and commissioned in DaFeng Port in the Chinese province of Jiangsu. The entire port handling machine has been supplied by Liebherr: All components were developed, produced and tested by Liebherr-Hydraulikbagger GmbH in Kirchdorf an der Iller, Germany; from the attachments to the work equipment, the hydraulic cab elevation and uppercarriage. The rail-mounted portal of this giant was developed in close cooperation with Liebherr- MCCtec Rostock GmbH. With an operating weight of approximately 200 tonnes, the machine is fitted with Liebherr’s standard ERC system, in addition to the engine power, it can also store energy when lowering the equipment available. This allows the LH 150 ET Gantry Port Litronic to achieve an output of up to 614 kW with energy savings of 30% at the same time. An additionally integrated high-voltage transformer reduces the 10 kV supply voltage of the local mains network to 400V which is then used to operate the main drive of the machine, a 400 kW Liebherr electric motor. Liebherr’s port handling machine is specifically tailored to meet the customer’s requirements. For example, the uppercarriage has not been seated in the conventional manner, centrally on the rail mounted portal. Instead it has been positioned off-centre, towards the side facing the sea. With its 16.5 m long, angled boom and 15 m long, straight stick, the LH 150 ET Gantry Port Litronic can cover the entire working area of a 10 thousand tonne timber-handling ship and more than 70% of a 30 thousand tonne timber-handling ship. The freely positionable spacious cab provides the operator with a perfect view and the Liebherr hydraulic quick coupler system is used to change the mechanically operated attachments quickly and safely from the cab. In total, approximately 207,000 containers and 51.14 million tonnes of material were handled in the port in 2018. DaFeng Port is the most important hub in the center of Jiangsu province. It is making enormous efforts to develop its four business areas of loading/unloading wind turbine blades, the timber trade, the RO-RO service and grain processing and to increase their efficiency.
