E-drive for mobile harbour cranes
We are confronted with the topic of greenhouse gas reduction on a daily basis. Moreover, both regulations and demands place specific requirements on the manufacturing industry to conserve resources and minimise CO2 emissions. Consequently, the transition to environmentally friendly drive types has long been essential.
Our electric drive enables you to operate your crane locally emission-free. Of course, an e-drive can be installed in a new machine from the beginning, but even as a retrofit kit the conversion of a diesel to an electrical drive offers significant benefits.
Transform your machine to dispense with fuel in your daily work and you will make your business more sustainable while also reducing operating costs.
Flexible drive systems for mobile harbour cranes
Liebherr offers various types of electric drive systems for its mobile harbour cranes, making an important contribution to improving energy efficiency and reducing emissions in the maritime industry.
- All-electric drive
- Electric-hydraulic drive
- Diesel-hydraulic drive
All-electric drive
The all-electric drive is connected to the local power grid, allowing for locally zero-emission operation. The drive concept offers two ways of energy recuperation. The electricity recovered from lowering can be fed back into the local power grid or stored in high-performance capacitors to retrieve the energy when needed. Both options reduce operational costs compared to conventional drive systems.

One cable drum, different options
We offer the option of a cable-reeling drum for the safe movement of the crane with the cable. Cable length can accommodate customer requirements depending on the voltage present at the feed point. This ensures emission-free lifting and electrical travel of the crane along the quayside.
Cable drum on undercarriage with low voltage
Cable drum on undercarriage with high voltage
High voltage cable drum outrigger

High voltage versus low voltage
For emission-free operation of your mobile harbour crane, you can choose two options depending on the harbour infrastructure. Connect your crane to a low voltage network from 400 volt or a high voltage network up to 20,000 volt. In case you use a high voltage supply, a converter installed on the undercarriage transforms high to low voltage. Thus, only low voltage is present in the crane itself.
