voestalpine AG is a leading global technology and industrial goods group with 500 group companies and locations. It focuses on product and system solutions made from steel and other metals. Under parent company voestalpine Stahl GmbH, its Steel Division is the division that generates the highest revenue. voestalpine Stahl GmbH operates a 100,000 m² scrapyard in Linz with annual throughput of around six million tonnes of steel.
Between 160 and 180 scrap charging boxes are loaded each day for the utilisation of the steelworks. In order to guarantee the five-shift operation runs smoothly 24 hours a day, seven days a week, and to supply the crude steel production with high-quality scrap material, optimal machine availability was a key purchasing criterion. Liebherr scored highly with the reliability of its material handlers and with excellent customer service.
Each LH 60 M Industry will achieve an average of 6,000 operating hours each year, which is why efficiency was extremely important to voestalpine in its choice of machine.
A particular challenge in the specification of the machine was that the grabs had to fit perfectly into the carriages being unloaded and at the same time have a high level of stability. As a result, Liebherr worked with voestalpine to develop and test a new bespoke five-tine grab for the LH 60 M Industry: the GMM 80-5 with a 0.9 m³ capacity and opening width of 2.34 m. The latter corresponds exactly to the width of a truck, meaning that the grab is also adapted to the carriage width.
