Liebherr Quarry Days attract over 1,000 visitors from all over the world

The over 1,000 visitors who attended the Quarry Days came from all over the world. They were mainly quarry operators who were interested in the knowledge and expertise of the Liebherr Group in this area. The Liebherr experts demonstrated the use of the quarrying equipment at various stations oriented towards the different production process in a quarry: material removal, quarrying, transportation, stone crushers and service.

Liebherr demonstrated the "material removal" with the R 946 crawler excavator and the PR 726 crawler tractor. Special crawler excavators were used for the "quarrying" stage: the R 960 SME Super Mass Excavation, the R 966 and the mining excavator R 9100 with operating weights of approx. 60 t, 65t and 110t. The new L 566 XPower® wheel loader demonstrated "transportation" in the quarry. At the "stone crusher" station, Liebherr showed an A 918 wheeled excavator, which was equipped with a hydraulic stone crusher for crushing stone blocks. The "service" station rounded off the programme. Liebherr informed the visitors about possible service agreements, the Reman programme and its tooth systems, among other things.

The diverse show, which took place four times daily, offered the opportunity to see a live demonstration of the various applications of the Liebherr machines. The R 9100 and R 956 crawler excavators, the L 586 XPower® wheel loader, the PR 756 crawler tractor, the LH 30 M material handler and the A 918 wheeled excavator were showcased. After the show all machines were available for customers to test out. The customers were able to experience the performance and efficiency of the Liebherr machines for themselves. A visit to the two crawler excavator production sites Liebherr-France SAS and Liebherr-Mining Equipment SAS in Colmar, France rounded off the programme.

R 956 crawler excavator

In Saint-Nabor, Liebherr showcased the R 956 crawler excavator for the first time with its new diesel engine, which meets the strict exhaust emissions standard of stage IV / Tier 4f. The R 956 crawler excavator, manufactured in Colmar, France, has an operating weight of 60 tonnes and delivers power of 240 kW / 326 bhp.

The new technical features in comparison to the previous model are similar to those of the R 946. This is the nearest smaller model, which was showcased for the first time at Intermat 2015 with stage IV / Tier 4f diesel engine. Thanks to its kinematics and hydraulic power, this model impresses with high breakout and feed forces of 316 kN and 249 kN. A more robust uppercarriage, a more resilient undercarriage and a new cab are other advantages of this new crawler excavator.

PR 726 crawler tractor

The new PR 726 was presented for the first time at NordBau in September 2015. It has an operating weight between 16,000kg and 19,800kg and its Liebherr diesel engine provides power of 120 kW / 163 bhp. The Liebherr PR 726 is driven by a 4-cylinder Liebherr diesel engine and meets the emissions standard of stage IV / Tier 4f.

The PR 726 offers exceptional smooth running and perfect crawling properties. Long running gear systems, an effective balance and best visibility are outstanding prerequisites for optimal levelling, irrespective of whether this is done manually or using automatic grading systems. The new PR 726 Litronic's performance is rounded off by a comprehensive range of equipment.

The L 566 XPower and L 586 XPower wheel loaders

During the Quarry Days in October Liebherr presented the new XPower® wheel loader to the public for the first time. XPower® represents the new generation of large Liebherr wheel loaders. It is an integral and innovative machine concept which sets new standards in terms of fuel efficiency, performance, robustness and comfort.

The core element of the XPower wheel loader is the power-split travel drive which conforms to stage IV / Tier 4f. Liebherr offers this travel drive as standard in these machines. It combines the hydrostatic drive, which is optimal for short loading cycles, and the mechanical drive, whose benefits are reaped over long distances and on steep gradients. The combination of these two drive types in a wheel loader ensures maximum efficiency and superb fuel savings for all requirements. The operator of a Liebherr-XPower wheel loader is able to save up to 30 percent on fuel.
