Liebherr to present new mid-size-class hydraulic mining excavator at Bauma

Among its booths at Bauma 2022, in Munich, Germany, from October 24-30, Liebherr is set to unveil a brand-new mid-size class hydraulic mining excavator.

This second Generation 8 machine will be joined by other mining products and solutions on the company’s stands at the world’s largest construction show.

A pre-series model of the new machine will be exhibited at the Liebherr booth. As the second machine within the Liebherr mining portfolio to receive the “Generation 8” label, after the R 9600 excavator, which was launched in 2021, this new model comes equipped with the latest Liebherr technology products, the company said.

The hydraulic excavator to be displayed at Bauma 2022 has already entered the testing phase, with the company planning the start of serial production in early 2024.

The T 274, a 305-t mining truck, will also be on display at the show, featuring what Liebherr says will be “an impressive demonstration of the Trolley Assist System”.

This new truck bridges the gap between the  T 284 (363 t) and the upgraded T 264 (240 t) and was launched last year with the Liebherr Trolley Assist System available as an option.

The Liebherr Trolley Assist System uses an overhead pantograph to connect the electric-drive system to a mine site’s electrical network, powered by the customer’s energy source of choice. The Trolley Assist System offers increased truck fleet productivity, and potential for reduction in fleet size while maintaining yearly production, when compared with standard trucks. The potential for significant reduction of diesel fuel consumption and carbon footprint by decreasing the truck fleet’s CO2 emissions, demonstrates the Trolley Assist System as an effective first step on the road to zero emission mine sites of the future, the company said.

Liebherr already delivers proven field experience with 56 Liebherr trucks fitted with the Trolley Assist System currently in operation across three mine sites, it said.

Liebherr Mining’s recently launched Technology Product portfolio will also be showcased at Bauma 2022.

Mining excavator technology products to be presented will include the Truck Loading Assistant, Performance Monitoring and Application Severity analytic products, Liebherr Power Efficiency, and the Bucket Filling Assistant, which offers the first step towards excavator automation.

Other innovations across the Liebherr Group set to be presented in Munich include Liebherr Components’ first hydrogen engine, the H964, with, the company says, high efficiency and very low NOx emissions with the same service life and maintenance intervals as diesel engines.

The various injection solutions for hydrogen for medium and heavy-duty engines, as well as large engines with 7-100 litre capacity, will also be presented.
