The globally operating Dutch crane and heavy haulage company Mammoet has taken delivery of the first electrically driven Liebherr mobile crane. The LTC 1050-3.1E is equipped with an electric motor in addition to the conventional drive. Crane movements can thus optionally be carried out using electricity. The new variant of the compact Liebherr 50-tonner thus contributes to CO2 reduction and meets the requirements for operation on “zero emission” construction sites.
Mammoet highlights the compactness of the LTC 1050-3.1, which offers greater flexibility when taking on jobs in tight locations, especially indoors, where both its zero emissions and noise reduction in electrical operation are particularly important.
Mammoet ordered the crane with Liebherr RemoteDrive for these operations. This allows the vehicle to be optimally controlled with remote control with centimetre precision under the tightest conditions.
The electric version of the LTC 1050-3.1 offers the best possible combination of environmental compatibility, customer benefits and efficiency. On and off the road, the 50-tonne crane is powered by a conventional and low-emission combustion engine with exhaust emission stage 5, delivering 243kW (326hp). The engine can be fed without restriction with hydrogenated vegetable oil (HVO), which already saves up to 90 % of CO2 emissions in operation, compared to pure diesel drive.
In crane operation, the combustion engine or electric motor can be flexibly selected depending on the operating conditions. The newly developed drive with electric motor offers an output of 72kW and thus enables unrestricted crane operation.
