For sale or for lease, building contractors, material handlers, and manufacturers will benefit from the 81K’s ease to use, enhanced lifting capacities, and over‐all versatility. Designed for a variety of job requirements, the 81K adapts to the needs of the user and to the task at hand. The Liebherr 81K represents a natural evolution of the self‐erecting crane. Originally introduced at CONEXPO 2011, the 81K has became an industry standard because of its exceptional adaptability and efficiency.
