Impressive qualities: Hans Dömkes GmbH continues to rely on Liebherr wheel loaders

Hans Dömkes GmbH recycles over 160,000 tonnes of mineral waste annually, using Liebherr wheel loaders for screening and crushing, and storing the sorted material in various storage areas.

Impressive qualities: Hans Dömkes GmbH continues to rely on Liebherr wheel loaders

For more than ten years, Liebherr wheel loaders have been used at the premises of the recycling company Hans Dömkes GmbH in Duisburg. Three wheel loaders – an L 538, an L 566 XPower® and an L 576 XPower® with High Lift arms – handle some of the material processed at the site. The specialists in recycling building materials state the fuel efficiency and excellent workmanship of the wheel loaders as the main reason for the long-standing business relationship with Liebherr. In addition, Liebherr's sales and service partner for the region, WBI Bau- und Industriemaschinen GesmbH, offers trusty and reliable service.

The recycled building materials are then loaded onto trucks by an L 576 XPower® with High Lift arms. The High Lift variant, available on customer request, offers increased reach and efficient loading at height. The recycled building materials are then reused in road construction and concrete mixing, as well as in gardening and landscaping.

Fuel efficiency of Liebherr wheel loaders as a purchasing criterion
More than a decade ago, Udo Dömkes, Managing Director of Dömkes GmbH, opted for a Liebherr wheel loader, leading to a partnership that continues to this day. "Back then, as now, we were impressed by the much lower fuel consumption yet higher performance compared to other wheel loaders in the same class size. Our XPower wheel loaders currently consume an average of eleven and a half to twelve litres of fuel per hour when heaping, reloading, and when feeding the screening and crushing plants," says the entrepreneur.

The fuel efficiency of the XPower generation of wheel loaders is due to the power-split XPower travel drive, which combines hydrostatic and mechanical propulsion. Hydrostatic power dominates when starting up and during short loading operations. When travelling at higher speeds and uphill, mechanical power comes more into play. Together, both components always transmit 100 percent of the diesel engine power, while only the ratio between them changes. This means the wheel loader always operates at maximum performance and efficiency, whatever it is being used for. The result is fuel savings of up to 30 percent compared to conventionally driven wheel loaders.

Markus Schepers, Liebherr wheel loader operator at Dömkes GmbH, adds: "The XPower drive system not only ensures low fuel consumption, but also a very comfortable ride. When heaping material, the wheel loader automatically and smoothly shifts between travel ranges, depending on how much force is required. This makes the work easier for the operator. In addition, numerous systems provide day-to-day assistance and ensure a safe working environment. An example of this is the active personnel detection with brake assistant, which reacts as soon as anyone comes close to the rear of the wheel loader. An alarm sounds and the brake assist system automatically reduces the speed of the wheel loader."

Impressive machine quality and rapid support
The intelligent installation of the components and cleverly designed access to the engine compartment ensure efficient maintenance work on the Liebherr wheel loaders. All installed parts, which need to be serviced can be reached safely and quickly. This saves time and money. Udo Dömkes is also convinced of this: "The quality of the Liebherr machines speaks for itself. Very rarely do we need a Liebherr service technician on site and when we do, help is guaranteed within 24 hours. This means that downtimes can be minimised. We feel excellently looked after."
