Liebherr giant headed for China

(Posted on 02/02/20)

The LH 150 ET Gantry Port Litronic is not only the first electrically-operated port handling machine in its weight class. It is also the world's largest electricallyoperated 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 LH 150 ET Gantry Port Litronic is the world's largest, electrically-operated Liebherr

port handling machine with gantry undercarriage. 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 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 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.

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

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. Operation of China's first electricallyoperated

Port handling machine in the 200-tonne category started officially with the handover.
