Contractors World Preview Intermat 2015 No 1
Liebherr Shows It’s Strength as an Innovator
As always, Liebherr will be putting on an impressive array of equipment. No other manufacturer has the depth or breadth when it comes to product ranges. At Intermat, visitors will see new products in the earthmoving equipment, tower cranes, mobile cranes and concrete technology.
Pride of place goes to the R946 crawler excavator with an operating weight of approximately 40 t. which will be the world premier. It is also the first excavator from Liebherr to meet stage IV/Tier 4F emission standards.
Excavators - New R946
- A new engine, developed and produced by Liebherr
- A selective catalytic reduction (SCR) system using urea injection to post-treat exhaust gases
A cutting edge technology to ensure high performance levels
- To coincide with the 2015 Intermat trade fair, Liebherr is unveiling the R 946, its first crawler excavator to meet the stage IV/ Tier 4f emissions standards.
The R 946 will be on display at the 2015 Intermat with a 6.45 m one-piece boom, a 2.9 m stick, a 2 m³ backhoe bucket and an LC undercarriage.
The new R 946 crawler excavator from Liebherr has an operating weight of approx. 40 tonnes. Its new Liebherr engine delivers 200 kW/272 hp. The 6-cylinder Liebherr engine integrates a new stage IV/ Tier 4f exhaust gas treatment system. This features a selective catalytic reduction (SCR) system using urea injection to post-treat exhaust gases.
The robust steel structure of the Liebherr R 946 crawler excavator is key to the machine’s reliability, especially in the most difficult applications. The undercarriage has been redesigned to improve the machine’s performance and service life.
The connection of the central component, which extends to the end of the side members provides better distribution of forces and increases the service life of the travel mechanism, thereby improving the equipment’s overall reliability.
The technology used in the integrated Liebherr systems ensure the crawler excavator offers high levels of performance. This technology is based on ‘Positive Control’ hydraulic systems, a smart system which uses sensors placed at strategic locations on an excavator.
Each operator control is processed by the control computer, which optimizes the operation of the engine and the hydraulic system. This ensures work is quick, smooth and precise. As needed, the circuits are separated or joined to ensure optimum use of energy.
In terms of maintenance, the R 946 crawler excavator has been designed to speed up operations carried out every day and improve machine availability. The maintenance areas are easy to access and the automatic central lubrication is fitted as standard.
The R 946 offers a spacious cab that provides a pleasant working environment for the driver. The seat has air suspension as standard to ensure maximum comfort, further enhanced by the ergonomic controls.
The large colour 7’’ touchscreen provides a high definition display, compatible with video, and boasts a range of setting, control and monitoring options. The image from the reversing camera, fitted as standard, can also be displayed on the on-board display.
The integrated roll-over protection (ROPS) in the cab complies with the ISO-121117 standard and ensures the driver remains safe in all situations. The lower windshield wiper, 360º camera and timed lights-out feature also help to optimise the working environment and ensure it is as safe as possible.
The R 950 SME “Super Mass Excavation”, developed using the R 946 base, is specially adapted to quarrying applications and accompanies the launch of this machine.
