Liebherr has reported construction and mining revenues for 2012 of ?5.9 billion, up 9 per cent year-on-year. The result was fuelled by a 28 per cent jump in revenues from the mining division to ?1.3 billion, while revenues from the mobile crane division also recovered after falling last year. Mobile crane revenues were up 12 per cent year-on-year in 2012 to ?1.9 billion. Revenues in the earthmoving and tower cranes and concrete technology divisions remained stable year-on-year at ?2.1 billion and ?580 million respectively. Liebherr said it had invested around ?560 million in its construction machinery and mining product areas during last year - up 26 per cent compared to 2011. More than half of this sum was devoted to the earthmoving division.
