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 electrically-operated Liebherr port handling machine with gantry undercarriage as well as the largest port handling machine Liebherr has ever produced.

The LH 150 ET Gantry Port Litronic has an operating weight of approximately 200 tonnes. It 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.

“The LH 150 ET Gantry Port Litronic is 2.5 times more productive than jib cranes for unloading wood,” said port vice general manager Lin Feng. “This shortens the waiting times of the ships and significantly reduces the cost of unloading the timber per tonne. This means that the operational efficiency of our port increases considerably making DaFeng Port more competitive.”

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.
