Liebherr showing two specialist waste handlers

Liebherr L542p wheel loader

Company to showcase material rehandler with rising cab and waste-specification wheel loader

THE recycling industry is growing rapidly – and changing. In recent years, many waste-disposal companies have developed from generalists to highly specialized recycling operations, which has brought with it a whole new set of challenges to be met by the machines used in the industry. Liebherr acknowledge this transformation and are developing machines and equipment options to meet every need and application.

At RWM 2014 the company will be exhibiting two machines which visitors will be able to inspect close up: the Liebherr LH22M, a 22-tonne material rehandler with rising cab; and the Liebherr L542p, a 13-tonne wheel loader with a 4 cubic metre bucket in waste specification.

The LH22M Litronic is the smallest machine type in the Liebherr product portfolio that is specially designed for material handling. Combining comfort, power and reliability, and offering excellent fuel efficiency with large loads and at long reaches, the machine is powerful, agile and versatile in its field of application, despite its compact dimensions.

Liebherr say they have managed to achieve this difficult balancing act thanks to their mature in-house engine technology and optimized demand-responsive hydraulics. Compared with the previous generation, fuel consumption has been reduced by up to 30%, yet the new Liebherr handlers have remained top performers in their class.

The LH22M’s exhaust gas after-treatment system features a Liebherr particulate filter, which is fitted as standard, while the service-orientated construction of the machine ensures shorter maintenance periods and minimizes associated maintenance costs.

Meanwhile, designed for economy and environmental friendliness, the new Stage IIIB/Tier 4i L542p wheel loader uses up to 25% less fuel than comparable machines from other manufacturers, under the same operating conditions. Up to 8% of this fuel advantage is achieved thanks to the new ‘Liebherr Power Efficiency’ (LPE) system.

By intelligent management of the individual units, LPE reduces both fuel consumption and component wear, with the engine management under proactive control and with all engine map characteristics and parameters being taken into account. LPE recognizes the performance profile required by the operator and puts it into action with maximum performance output in the most efficient way possible.

Also, thanks to the tried and trusted Liebherr travel drive, tyre wear is reduced by up to 25%, while the service brake is practically free of wear altogether.

For increased productivity, the L542’s cab is particularly spacious and comfortable for the operator. All operating elements are conveniently and ergonomically matched to one another, while the hydraulic cab bearing system substantially reduces interior cab noise and vibration.

The new generation of Stage IIIB diesel engines feature precision common-rail fuel injection, which optimizes the combustion process and reduces pollutant emissions. Exhaust emission control uses a diesel-oxidating catalytic converter combined with a diesel particulate filter. In most situations, the filter can be actively regenerated by burning off deposits during machine operation, allowing the work in progress to continue without interruption.

Moreover, in this wheel loader class the diesel engine has been rotated through 90 degrees and mounted transverse to the direction of travel. Compared with the conventional wheel loader engine configuration, this results in a lower operating weight and a higher tipping load, thereby allowing more material to be moved each operating hour.

Stand: 5P10-R11
