Based on the concept of the 71 K model, the new fast-erecting 81 K lifts loads more than 25% higher at the end of the jib, Liebherr said. The 6t capacity crane has a maximum hook height of 40.4m and 55m at a 30˚ jib angle.
Transport dimensions haven’t change much from the 71 K, but the 81 K now has a 2.75m slewing radius. Tower sections measure 2.4m-long, allowing them to be carried sideways on a truck. These new sections can be used with the 71 K, and vice versa.
