Engineer Sven Heinisch manages the corporate group USUM, founded by his father in 1992, in the town of Steigra (50 km south-west of Halle/Saale). USUM stands for Unstrut-Saale-Umweltschutz (Unstrut-Saale Environmental Protection). The group USUM Grundstoffaufbereitung und Service GmbH operates a roughly seven-hectare industrial site on the recultivated former rubble dump site of an open-cast limestone quarry. Today, the business has a team of eight employees and produces: compost certified for agricultural use by the German Institute for Quality Assurance and Certification (RAL), soil, mineral potash fertiliser and recyclable materials from mineral construction site waste.
Since September 2020, the company has been using a new Hyundai HL965 wheel loader with an operating weight of 20-tonne and 201 kW net power (with a 3.5-m3 bucket) in addition to a new 13-tonne HL940A machine of the same series, with 116 kW net power (2.5-m3 bucket). Both wheel loaders are used for assembling and turning compost piles, loading recyclable materials onto trucks, and general loading operations and cleaning work.
Heinisch bought the new wheel loaders from the Hyundai dealership Tecklenborg Baumaschinen GmbH based in the town of Leisnig and had them custom-equipped to meet his specific needs. "The 45% subsidy we received from a programme for reducing CO2 emissions enabled us to buy these modern, highly economical Hyundai wheel loaders, and trade in two very old vehicles," explains Heinisch. Wheel loader operator Udo Hartung, who operates the HL940A daily through difficult and heavy recycling operations, is also delighted with the high-precision operability of this quiet-running wheel loader. The vehicle's low fuel consumption of some six-litres per hour is also a winning factor.
A climate-controlled operator's cabin is an indispensable feature for often odour-intensive recycling operations. The HL965 wheel loader is additionally equipped with a protective ventilation system from the company SEKA. The SEKA system isn't required on the HL940A as the machine is fitted with the latest-generation cabin technology, however, it was the company's choice as an added comfort benefit for the operator.
Tecklenborg takes charge of all loader service and repair work, and USUM Recycling is highly satisfied with the service they have provided. The wheel loaders are used for up to 1,500 hours annually.
Automatic engine shutdown control keeps fuel consumption and emissions under strict control at the right time. When HL-series loaders are idling, the engine switches off automatically after
