First electrically-operated Liebherr port handling machine now in operation in DaFeng Port
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. The rail-mounted portal of this giant was developed in close cooperation with Liebherr-MCCtec Rostock GmbH.
With an operating weight of approximately 200t, the LH 150 ET Gantry Port Litronic is the largest port handling machine ever made by Liebherr. 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 614kW with energy savings of 30% at the same time. An additionally integrated high-voltage transformer reduces the 10kV supply voltage of the local mains network to 400V which is then used to operate the main drive of the machine, a 400kW 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 16.5m long, angled boom and 15m long, straight stick, the LH 150 ET Gantry Port Litronic can cover the entire working area of a 10,000t timber-handling ship and more than 70% of a 30,000t tonne timber-handling ship. The freely positionable spacious cab provides the operator with a clear view and the Liebherr hydraulic quick coupler system is used to change the mechanically operated attachments quickly and safely from the cab.
For Liebherr, it was very important to involve the customer in each stage of the overall project. 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.
As part of the handover celebrations Joachim Strobel, managing director sales at Liebherr-EMtec GmbH), symbolically handed a large golden key to the general manager of DaFeng Port, Ji Xiaobo. Operation of China’s first electrically-operated port handling machine in the 200t category started officially with the handover.
During the handover ceremony, Ji Xiaobo emphasized that “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.”
