Liebherr at Conexpo 2014

BIBERACH/GERMANY, February 4, 2014 - During Conexpo Con/Agg 2014, Liebherr will present an extensive selection of its Earthmoving, Material Handling and Construction Equipment product range. The Liebherr outdoor stand will be located at the Las Vegas Convention Center, Gold Lot 2155.

From March 4-8, 2014, Liebherr will display more than 20 pieces of equipment for multiple industries and job applications. The Liebherr booth covers 50,000 ft2 (4,600 m2) and provides room for three hydraulic excavators, three wheel loaders, three crawler loaders and tractors, one deep foundation machine, two material handlers, two tower cranes, six mobile and crawler cranes as well as one concrete pump. For the first time on display at Conexpo, Liebherr will present various components from the mechanical, hydraulic and electric drive systems competency areas.

R 956 Crawler Excavator – a new Development in the 50-Tonne Class

The new R 956 standard hydraulic excavator weighs approximately 122,100 lb (55,400 kg) and replaces the previous R 954 model.
The R 956 is equipped with a Liebherr 6-cylinder diesel engine with common rail fuel injection. Among the features enabling this engine to comply with Tier 4i / stage IIIB exhaust emission standards are an external exhaust gas recirculation system and a diesel particulate filter with active regeneration.
The steelwork for the new R 956’s uppercarriage has been optimized for extended service life. A wide variety of undercarriages are available to suit any application. The LC is the typical under-carriage for earthmoving applications, two ‘heavy-duty’-undercarriages HD and S-HD are also available for quarry applications.

PR 736 Dozer to be introduced to the US-Market

With a service weight of 44,000 to 55,115 lb (20,000-25,000 kg), the PR 736 dozer, is not only a new development but also the first model in the new Generation 6 series. Priorities in its development were measures to increase efficiency and to reduce fuel consumption and CO2 emissions.
Among the innovations on the Generation 6 models are electronic travel speed regulation with an integral eco-function, and pro-active power control.
To simplify the use of automatic machine control systems, Liebherr can supply its Generation 6 crawler tractors and loaders with factory preparation kits for leading manufacturers control systems.
The modern design of the new Generation 6 crawler tractors provides the driver with a good all-round view of the terrain and the machine’s working attachments. The operator cab is a completely new design with ergonomically located controls. The seat can be optimally positioned to suit the operator’s preferences.

Newest Generation of Material Handlers: the LH 40 M and LH 60 C

Liebherr is presenting the LH 40 M mobile industrial handler and LH 60 C tracked industrial handler from its new series of material-handling machines at Conexpo Con/Agg 2014 in Las Vegas (USA).
The Liebherr LH 40 M and LH 60 C handling machines combine comfort, performance and reliability to provide customers greater efficiency and low operating costs. They deliver a new level of economy as the result of their high load capacities and superior reach. Specially developed for material handling, both machines also comply with the requirements of Tier 4i / stage IIIB emissions regulations.
Efficiency comes standard on the LH 40 M and LH 60 C. Both are equipped with the Liebherr Energy Recovery System (ERC) as standard. The additional hydraulic cylinder helps to increase the handling capacity while reducing fuel consumption. The machine features Liebherr Power Efficiency system (LPE) which optimizes the interaction between the drive components and therefore increases the efficiency and optimizes the engine’s power output.

542 HC-L luffing Jib Crane

The 542 HC-L 18/36 Litronic luffing jib crane has a maximum load capacity of 79,366 lb (36,000 kg). The luffing gear has been optimized dependent on lifting capacity so that shorter adjusting times are possible. At a high crane density, this can be a crucial factor.
The 542 HC-L has infinitely adjustable FC drive units. The entry-level model 542 HC-L 18/36 Litronic includes a 110 kW FC hoist unit, a 110 kW FC luffing gear unit with secondary brake, as well as two 11 kW FC slewing gear units as standard equipment for precise and targeted load handling.
The 542 HC-L is always supplied in the easy-to-use Litronic version. Using the programmable logic controller PLC, the load can be moved at the touch of a button in the same way as with a trolley jib top-slewing crane in a level luffing movement. Another component of the Litronic concept is the tried and trusted MICROMOVE. It permits high-precision positioning of the load without the hoist gear brake engaging, for safe and efficient crane operations.

Premiere at Conexpo: Liebherr Components on display

For the first time on display at Conexpo, Liebherr presents various innovative components in a special pavilion within the Liebherr booth. The exhibits from the mechanical, hydraulic and electric drive systems areas have been developed and manufactured at Liebherr’s various competence centers.
The display includes the latest generation of Liebherr diesel engines. The engine on display complies with the USA EPA Tier 4 final exhaust emission limits that come into effect in 2014. Liebherr uses Selective Catalytic Reduction (SCR) exclusively on these engines, an innovative technology that makes particulate filters unnecessary. The SCR system by Liebherr is particularly outstanding for its small installation space. The hydraulic driveline consists of splitter box and several hydraulic pumps, and it is mounted to the V8 engine on display. This driveline demonstrates the system proficiency of the Liebherr-Components.
The new common-rail fuel injection system, with Liebherr’s own engine control unit are another highlight in the Components pavilion. These systems are standard equipment on Liebherr V4-V12 engines and can be adapted for use on other manufacturers’ diesel engines. Liebherr common-rail systems are notable for their exceptionally low fuel consumption and efficient combustion, both factors reduce exhaust emissions.
