The largest port handling machine Liebherr has ever produced, the LH 150 ET Gantry Port Litronic is now in operation in DaFeng Port in China. It is also the world’s largest electrically operated Liebherr port handling machine with gantry undercarriage.
With an operating weight of approximately 200 tonnes, the LH 150 ET Gantry Port Litronic 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 that 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 10,000-tonne timber-handling ship and more than 70% of a 30,000-tonne timber-handling ship.
Technicians from DaFeng Port were present in the manufacturing facility in Kirchdorf an der Iller during the assembly process in order to gain in depth knowledge about this bespoke Liebherr machine. Engineers from Liebherr-Hydraulikbagger GmbH provided support in DaFeng Port for the entire build, commissioning and operator training.
Representatives from the earthmoving division travelled to Dafeng, Jiangsu, to take part in the handover celebrations. As part of the ceremony Joachim Strobel (Managing Director Sales, Liebherr-EMtec GmbH) symbolically handed a large golden key to the general manager of DaFeng Port, Ji Xiaobo.
During the handover ceremony, Ji Xiaobo, said, “The use of the electrically-operated port handling machine is of huge importance to DaFeng Port and our goal of developing DaFeng Port as a “green port”. The LH 150 ET Gantry Port Litronic will also help DaFeng Port achieve an annual handling capacity of 100 million tonnes”.
In total, approximately 207,000 containers and 51.14 million tonnes of material were handled in the port in 2018.
