- Hybrid power concept: Local emission-free operation possible
- Use of site electricity significantly more cost-efficient than running on diesel
- HVO fuel for travel possible straight from the factory
The days when construction site machines could only run on diesel are over. Liebherr’s mobile construction cranes are no longer limited to fossil fuels. HVO, an alternative fuel, can be used for travel from one location to the next. Site electricity or a mobile battery-based energy storage system are options for supplying power once the crane arrives at its destination.
Liebherr’s mobile construction cranes are taxi cranes, moving from one site to the next. They are quick and easy to erect and operate; only one person is needed for the job. The use of alternative fuels like HVO is possible for travelling from site to site. Both the superstructure and undercarriage can be powered by this fossil-free alternative.
Crane operation without diesel engine possible
The mobile construction crane can be operated in electric mode using site electricity instead of its diesel engine. This hybrid power concept enables the crane to operate locally with zero emissions and very little noise – an advantage when working in residential areas or on night-time construction sites. Using site power makes crane operation significantly more cost-efficient. Over a year, this results in only 10 percent of the operating costs associated with use of a diesel engine.
If there is insufficient or no on-site power available, Liebherr’s mobile battery-based energy storage system Liduro Power Port (LPO) is able to take over supply, so that hybrid or all-electric construction machines can be operated and charged locally with zero emissions. A diesel-powered generator is a further available option.
Existing cranes can be powered by HVO
The alternative fuel HVO (hydrotreated vegetable oils) can be used to power cranes in its pure form or mixed with diesel to any required ratio. Fuel for Liebherr machines comes from food industry waste; palm oil isn’t used. By reducing exhaust gases, HVO helps to limit global greenhouse gas emissions. The fuel is fully compatible with all engine components.
