The shift in the industry towards electrified machines - even in the heavier weight classes - will be demonstrated on the enormous Liebherr stand at this year鈥檚 Bauma.

The German manufacturing giant returns to the Munich event this year under the theme of 鈥極n Your Site鈥�, where, from the biggest single structure in the outdoor grounds, it will show more than 70 exhibits of its construction equipment, much of which will be zero-emissions machines.

The 14,000m2 outdoor area occupied by Liebherr at Bauma includes two product segments for earthmoving and material handling equipment, as well as six new products from the piling, drilling and lifting segments from its Unplugged series.

Included in the series is the LRH 100.1 and LRH 200 piling rigs, which can operate for up to five hours in battery mode, with a 200kWh battery package, or up to ten hours with a 400kWh battery option.

Unplugged versions of Liebherr鈥檚 LB 25 and LB 30 drilling rigs will also be exhibited.

Liebherr is well known for its range of cranes, and these too have joined the Unplugged family, with the LR 1130.1 and LR 1160.1 unplugged crawler cranes to be exhibited.

Both cranes have the same performance data as their conventional versions and operate in a similar manner.

Liebherr will also present a new crawler crane to the Bauma audience: the LR 12500- 1.0, with a 2,500-tonne load-bearing capacity. The company says the design of the rotating platform and main boom have been enhanced, with an 鈥渦nrivalled鈥� wide main boom giving the crane the stability of a power boom.

Other product highlights from Liebherr include a new series of stationary mixing plants. The Betomix and Mobilmix plants can be combined from prefabricated modules, allowing for the straightforward replacement of predecessor models.

While this means easier configuration of plants for customers, along with faster delivery times and more readily available parts, the optimisation of drives also promises power consumption reductions of up to 30%, as well as greater accuracy in the weighing of cement.

Advanced technology will also be among the highlights of Liebherr鈥檚 exhibit this year, with the company presenting IoT solutions for increased data security and the LiXplore camera monitor 鈥� which includes a digital wear measurement system, able to monitor large diameter bearings.

Liebherr will also exhibit its first hydrogen engine concept, the H964, which promises high efficiency combined with very low NOx emissions.

According to Liebherr, the engine will have the same service life and maintenance intervals as a comparable diesel engine.
