The Colas-Sarrazy branch uses an R 945, the heaviest Generation 8 model, in its “Multi-user” configuration with a 10.70 m Boom and 7.70 m Stick. The machine is in charge of cleaning the sludge tanks in one of the group’s local gravel pits. On-board systems, such as demand-driven power regulation and the Liebherr Positive Control hydraulic system, provide adequate and sufficient power to penetrate the tanks bottom. This model of nearly 45 tonnes, replacing the R 950 SME, is also distinguished by its completely new basic concept, its comfort whatever the application is and its ever better operating performance.

Excavation work at great depths requires the use of longer attachments. For such applications, Liebherr has developed “multi-user” attachments perfectly tailored to its machines. Our multi-user attachments allow operations to be carried out at distant or deep locations. This attachment version is available for crawler excavator models R 922 to R 976 Litronic. Its range varies from 15 to 23 m depending on model and type of boom.

A Liebherr R 950 Tunnel crawler excavator is being deployed on construction sites for the Grand Paris Express. As part of this huge project, our crawler excavator is in action in shaft 807 of Line 15, performing extraction work with a cutter, installing arches and handling various kinds of loose materials. The Alliance Group is very satisfied with this 45 tonne Liebherr machine.

Construction work in tunnels poses specific challenges: confined spaces, dust and limited visibility are factors that increase the difficulty of underground work. Liebherr tunnelling excavators have been developed for these specific conditions. Their narrow slewing radius allows these machines to turn in tight spaces, and the tunnel excavator has automatic height limitation, allowing it to work only within pre-set height limits. Cameras make the operator’s job even easier.

For its metal waste recycling activity, the Belgian company Ijzerland has chosen performance while respecting the environment. It was to meet these needs that it chose the Liebherr electric material handling excavator R 944 C-E in its High Rise version.

Protecting the environment and sustainability are becoming increasingly important in all areas of life. Companies also want to contribute to achieving these goals. Our electric crawler excavators offer zero-emissions operation without compromising on the proven performance of Liebherr excavators’.

The R 934 C, R 944 C and R 954 C models are part of Liebherr’s range of 100% electric materials handling machines. A single electric motor for all hydraulic functions (actuator concept) makes machine service and maintenance very easy. Sensitive electro-hydraulic controls ensure high accuracy in operation.

For the unloading of coal from the Shakhtersk terminal in Russia, EMCO opted for four Liebherr R 976 crawler excavators. The quality and robustness of the machines as well as the performance of the Liebherr service on-site are essential.

Our customer Samsun Engineering Unit uses a Liebherr dredging excavator on the Black Sea to dredge the sea floor. With a vessel equipped with a downward-opening hold, the company can move between 500 and 750 m³ per day. The bucket volume is about 4 cm³. Because the sea is not deep, they use a short boom. This has the advantage that almost all the power can be transferred to the bucket. The P 954 works reliably and flawlessly despite the sudden difficult weather con-ditions that occur time and again.

The P 954 C Liebherr dredging excavator, adapted to this salty and windy environment, is ready for action and robust, just as it was on the first day. Compared to the dredgers used in land operations, it is more robust with regard to the corrosion-resistant paint and primer.
